Bump version and soname for 5.2.5.

"make dist" updates the .po files and the fuzzy strings would
result in multiple very wrong translations.

+# Very limited CMake support for building some parts of XZ Utils
+#
+# Building static liblzma with MSVC should work. Building shared liblzma.dll
+# with MSVC may or may not work (building liblzma_w32res.rc might be broken).
+# Building liblzma on a few other platforms should work too but it
+# is somewhat experimental and not as portable as using ./configure.
+#
+# On some platforms this builds also xz and xzdec, but these are
+# highly experimental and meant for testing only:
+#   - No large file support on those 32-bit platforms that need it
+#   - No replacement getopt_long(), libc must have it
+#   - No sandboxing support
+#   - No translations
+#   - No xz symlinks are installed
+#
+# Other missing things:
+#   - No xzgrep or other scripts or their symlinks
+#   - No tests (no test failures either!)
+#
+# NOTE: Even if the code compiles without warnings, the end result may be
+# different than via ./configure. Specifically, the list of #defines
+# may be different (if so, probably this CMakeLists.txt got them wrong).
+#
+# This file provides the following installation components (if you only
+# need liblzma, install only its components!):
+#   - liblzma_Runtime
+#   - liblzma_Development
+#   - xz (on some platforms only)
+#   - xzdec (on some platforms only)
+#
+# To find the target liblzma::liblzma from other packages, use the CONFIG
+# option with find_package() to avoid a conflict with the FindLibLZMA module
+# with case-insensitive file systems. For example, to require liblzma 5.2.5
+# or a newer compatible version:
+#
+#     find_package(liblzma 5.2.5 REQUIRED CONFIG)
+#     target_link_libraries(my_application liblzma::liblzma)

+
+                The reasons to use this option:
+
+                  - It makes liblzma slightly smaller.
+
+                  - It might improve SHA-256 speed if the implementation
+                    in the operating is very good (but see below).
+
+                External SHA-256 is disabled by default for two reasons:
+
+                  - On some operating systems the symbol names of the
+                    SHA-256 functions conflict with OpenSSL's libcrypto.

+                    other OSes that provide a function "SHA256_Init" might
+                    also be affected. FreeBSD 11 has the problem fixed.
+                    NetBSD had the problem but it was fixed it in 2009
+                    already. OpenBSD uses "SHA256Init" and thus never had

+          versions or compilers other than GCC and Clang. The configure
+          option --enable-unsafe-type-punning can be used to (mostly)
+          restore the old behavior but it shouldn't normally be used.
+
+        - Improved API documentation of lzma_properties_decode().
+
+        - Added a very minor encoder speed optimization.
+
+    * xz:
+
+        - Fixed a crash in "xz -dcfv not_an_xz_file". All four options
+          were required to trigger it. The crash occurred in the
+          progress indicator code when xz was in passthru mode where
+          xz works like "cat".
+
+        - Fixed an integer overflow with 32-bit off_t. It could happen
+          when decompressing a file that has a long run of zero bytes
+          which xz would try to write as a sparse file. Since the build
+          system enables large file support by default, off_t is
+          normally 64-bit even on 32-bit systems.
+
+        - Fixes for --flush-timeout:
+            * Fix semi-busy-waiting.
+            * Avoid unneeded flushes when no new input has arrived
+              since the previous flush was completed.
+
+        - Added a special case for 32-bit xz: If --memlimit-compress is
+          used to specify a limit that exceeds 4020 MiB, the limit will
+          be set to 4020 MiB. The values "0" and "max" aren't affected
+          by this and neither is decompression. This hack can be
+          helpful when a 32-bit xz has access to 4 GiB address space
+          but the specified memlimit exceeds 4 GiB. This can happen
+          e.g. with some scripts.
+
+        - Capsicum sandbox is now enabled by default where available
+          (FreeBSD >= 10). The sandbox debug messages (xz -vv) were
+          removed since they seemed to be more annoying than useful.
+
+        - DOS build now requires DJGPP 2.05 instead of 2.04beta.
+          A workaround for a locale problem with DJGPP 2.05 was added.
+
+    * xzgrep and other scripts:
+
+        - Added a configure option --enable-path-for-scripts=PREFIX.
+          It is disabled by default except on Solaris where the default
+          is /usr/xpg4/bin. See INSTALL for details.
+
+        - Added a workaround for a POSIX shell detection problem on
+          Solaris.
+
+    * Build systems:
+
+        - Added preliminary build instructions for z/OS. See INSTALL
+          section 1.2.9.
+
+        - Experimental CMake support was added. It should work to build
+          static liblzma on a few operating systems. It may or may not
+          work to build shared liblzma. On some platforms it can build
+          xz and xzdec too but those are only for testing. See the
+          comment in the beginning of CMakeLists.txt for details.
+
+        - Visual Studio project files were updated.
+          WindowsTargetPlatformVersion was removed from VS2017 files
+          and set to "10.0" in the added VS2019 files. In the future
+          the VS project files will be removed when CMake support is
+          good enough.
+
+        - New #defines in config.h: HAVE___BUILTIN_ASSUME_ALIGNED,
+          HAVE___BUILTIN_BSWAPXX, and TUKLIB_USE_UNSAFE_TYPE_PUNNING.
+
+        - autogen.sh has a new optional dependency on po4a and a new
+          option --no-po4a to skip that step. This matters only if one
+          wants to remake the build files. po4a is used to update the
+          translated man pages but as long as the man pages haven't
+          been modified, there's nothing to update and one can use
+          --no-po4a to avoid the dependency on po4a.
+
+    * Translations:
+
+        - XZ Utils translations are now handled by the Translation
+          Project: https://translationproject.org/domain/xz.html
+
+        - All man pages are now included in German too.
+
+        - New xz translations: Brazilian Portuguese, Finnish,
+          Hungarian, Chinese (simplified), Chinese (traditional),
+          and Danish (partial translation)
+
+        - Updated xz translations: French, German, Italian, and Polish
+
+        - Unfortunately a few new xz translations weren't included due
+          to technical problems like too long lines in --help output or
+          misaligned column headings in tables. In the future, many of
+          these strings will be split and e.g. the table column
+          alignment will be handled in software. This should make the
+          strings easier to translate.
+
+
+5.2.4 (2018-04-29)
+
+    * liblzma:
+
+        - Allow 0 as memory usage limit instead of returning
+          LZMA_PROG_ERROR. Now 0 is treated as if 1 byte was specified,
+          which effectively is the same as 0.
+
+        - Use "noexcept" keyword instead of "throw()" in the public
+          headers when a C++11 (or newer standard) compiler is used.
+
+        - Added a portability fix for recent Intel C Compilers.
+
+        - Microsoft Visual Studio build files have been moved under
+          windows/vs2013 and windows/vs2017.
+
+    * xz:
+
+        - Fix "xz --list --robot missing_or_bad_file.xz" which would
+          try to print an uninitialized string and thus produce garbage
+          output. Since the exit status is non-zero, most uses of such
+          a command won't try to interpret the garbage output.
+
+        - "xz --list foo.xz" could print "Internal error (bug)" in a
+          corner case where a specific memory usage limit had been set.
+
+
+5.2.3 (2016-12-30)
+
+    * xz:
+
+        - Always close a file before trying to delete it to avoid
+          problems on some operating system and file system combinations.
+
+        - Fixed copying of file timestamps on Windows.
+
+        - Added experimental (disabled by default) sandbox support using
+          Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL.
+
+    * C99/C11 conformance fixes to liblzma. The issues affected at least
+      some builds using link-time optimizations.
+
+    * Fixed bugs in the rarely-used function lzma_index_dup().
+
+    * Use of external SHA-256 code is now disabled by default.
+      It can still be enabled by passing --enable-external-sha256
+      to configure. The reasons to disable it by default (see INSTALL
+      for more details):
+
+        - Some OS-specific SHA-256 implementations conflict with
+          OpenSSL and cause problems in programs that link against both
+          liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0
+          are affected.
+
+        - The internal SHA-256 is faster than the SHA-256 code in
+          some operating systems.
+
+    * Changed CPU core count detection to use sched_getaffinity() on
+      GNU/Linux and GNU/kFreeBSD.
+
+    * Fixes to the build-system and xz to make xz buildable even when
+      encoders, decoders, or threading have been disabled from libilzma
+      using configure options. These fixes added two new #defines to
+      config.h: HAVE_ENCODERS and HAVE_DECODERS.
+
+
+5.2.2 (2015-09-29)
+
+    * Fixed bugs in QNX-specific code.
+
+    * Omitted the use of pipe2() even if it is available to avoid
+      portability issues with some old Linux and glibc combinations.
+
+    * Updated German translation.
+
+    * Added project files to build static and shared liblzma (not the
+      whole XZ Utils) with Visual Studio 2013 update 2 or later.
+
+    * Documented that threaded decompression hasn't been implemented
+      yet. A 5.2.0 NEWS entry describing multi-threading support had
+      incorrectly said "decompression" when it should have said
+      "compression".

-4. Translating the xz tool
---------------------------
+4. Translations
+---------------
 
-    The messages from the xz tool have been translated into a few
-    languages. Before starting to translate into a new language, ask
-    the author whether someone else hasn't already started working on it.
+    The xz command line tool and all man pages can be translated.
+    The translations are handled via the Translation Project. If you
+    wish to help translating xz, please join the Translation Project:
 
-    Test your translation. Testing includes comparing the translated
-    output to the original English version by running the same commands
-    in both your target locale and with LC_ALL=C. Ask someone to
-    proof-read and test the translation.
+        https://translationproject.org/html/translators.html
 
-    Testing can be done e.g. by installing xz into a temporary directory:
-
-        ./configure --disable-shared --prefix=/tmp/xz-test
-        # <Edit the .po file in the po directory.>
-        make -C po update-po
-        make install
-        bash debug/translation.bash | less
-        bash debug/translation.bash | less -S  # For --list outputs
-
-    Repeat the above as needed (no need to re-run configure though).
-
-    Note especially the following:
-
-      - The output of --help and --long-help must look nice on
-        an 80-column terminal. It's OK to add extra lines if needed.
-
-      - In contrast, don't add extra lines to error messages and such.
-        They are often preceded with e.g. a filename on the same line,
-        so you have no way to predict where to put a \n. Let the terminal
-        do the wrapping even if it looks ugly. Adding new lines will be
-        even uglier in the generic case even if it looks nice in a few
-        limited examples.
-
-      - Be careful with column alignment in tables and table-like output
-        (--list, --list --verbose --verbose, --info-memory, --help, and
-        --long-help):
-
-          * All descriptions of options in --help should start in the
-            same column (but it doesn't need to be the same column as
-            in the English messages; just be consistent if you change it).
-            Check that both --help and --long-help look OK, since they
-            share several strings.
-
-          * --list --verbose and --info-memory print lines that have
-            the format "Description:   %s". If you need a longer
-            description, you can put extra space between the colon
-            and %s. Then you may need to add extra space to other
-            strings too so that the result as a whole looks good (all
-            values start at the same column).
-
-          * The columns of the actual tables in --list --verbose --verbose
-            should be aligned properly. Abbreviate if necessary. It might
-            be good to keep at least 2 or 3 spaces between column headings
-            and avoid spaces in the headings so that the columns stand out
-            better, but this is a matter of opinion. Do what you think
-            looks best.
-
-      - Be careful to put a period at the end of a sentence when the
-        original version has it, and don't put it when the original
-        doesn't have it. Similarly, be careful with \n characters
-        at the beginning and end of the strings.
-
-      - Read the TRANSLATORS comments that have been extracted from the
-        source code and included in xz.pot. If they suggest testing the
-        translation with some type of command, do it. If testing needs
-        input files, use e.g. tests/files/good-*.xz.
-
-      - When updating the translation, read the fuzzy (modified) strings
-        carefully, and don't mark them as updated before you actually
-        have updated them. Reading through the unchanged messages can be
-        good too; sometimes you may find a better wording for them.
-
-      - If you find language problems in the original English strings,
-        feel free to suggest improvements. Ask if something is unclear.
-
-      - The translated messages should be understandable (sometimes this
-        may be a problem with the original English messages too). Don't
-        make a direct word-by-word translation from English especially if
-        the result doesn't sound good in your language.
-
-    In short, take your time and pay attention to the details. Making
-    a good translation is not a quick and trivial thing to do. The
-    translated xz should look as polished as the English version.
+    Several strings will change in a future version of xz so if you
+    wish to start a new translation, look at the code in the xz git
+    repostiory instead of a 5.2.x release.

-    not be the most convenient way taking into account what components

+    from readme.1st too).
 
     For a more manual method, first select a mirror from
-    <http://www.delorie.com/djgpp/getting.html>. You need
-    the following files:

+# SYNOPSIS
+#
+#   AX_CHECK_CAPSICUM([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro searches for an installed Capsicum header and library,
+#   and if found:
+#     - AC_DEFINE([HAVE_CAPSICUM]) is called.
+#     - AC_DEFINE([HAVE_SYS_CAPSICUM_H]) is called if <sys/capsicum.h>
+#       is present (otherwise <sys/capability.h> must be used).
+#     - CAPSICUM_LIB is set to the -l option needed to link Capsicum support,
+#       and AC_SUBST([CAPSICUM_LIB]) is called.
+#     - The shell commands in ACTION-IF-FOUND are run. The default
+#       ACTION-IF-FOUND prepends ${CAPSICUM_LIB} into LIBS. If you don't
+#       want to modify LIBS and don't need to run any other commands either,
+#       use a colon as ACTION-IF-FOUND.
+#
+#   If Capsicum support isn't found:
+#     - The shell commands in ACTION-IF-NOT-FOUND are run. The default
+#       ACTION-IF-NOT-FOUND calls AC_MSG_WARN to print a warning that
+#       Capsicum support wasn't found.
+#
+#   You should use autoheader to include a definition for the symbols above
+#   in a config.h file.
+#
+#   Sample usage in a C/C++ source is as follows:
+#
+#     #ifdef HAVE_CAPSICUM
+#     # ifdef HAVE_SYS_CAPSICUM_H
+#     #  include <sys/capsicum.h>
+#     # else

+// Separate functions for aligned reads and writes are provided since on
+// strict-align archs aligned access is much faster than unaligned access.
+//
+// Just like in the unaligned case, memcpy() is needed to avoid
+// strict aliasing violations. However, on archs that don't support
+// unaligned access the compiler cannot know that the pointers given
+// to memcpy() are aligned which results in slow code. As of C11 there is
+// no standard way to tell the compiler that we know that the address is
+// aligned but some compilers have language extensions to do that. With
+// such language extensions the memcpy() method gives excellent results.
+//
+// What to do on a strict-align system when no known language extentensions
+// are available? Falling back to byte-by-byte access would be safe but ruin
+// optimizations that have been made specifically with aligned access in mind.
+// As a compromise, aligned reads will fall back to non-compliant type punning
+// but aligned writes will be byte-by-byte, that is, fast reads are preferred
+// over fast writes. This obviously isn't great but hopefully it's a working
