3ce3e79769 xz: Check for filter chain compatibility for --flush-timeout.
This avoids LZMA_PROG_ERROR from lzma_code() with filter chains
that don't support LZMA_SYNC_FLUSH.

ceca379017 xzgrep: exit 0 when at least one file matches.
Mimic the original grep behavior and return exit_success when
at least one xz compressed file matches given pattern.

Thanks to Pavel Raiskup for the patch.

da1718f266 liblzma: Use lzma_alloc_zero() in LZ encoder initialization.
This avoids a memzero() call for a newly-allocated memory,
which can be expensive when encoding small streams with
an over-sized dictionary.

To avoid using lzma_alloc_zero() for memory that doesn't
need to be zeroed, lzma_mf.son is now allocated separately,
which requires handling it separately in normalize() too.

Thanks to Vincenzo Innocente for reporting the problem.

4d5b7b3fda liblzma: Rename the private API header lzma/lzma.h to lzma/lzma12.h.
It can be confusing that two header files have the same name.
The public API file is still lzma.h.

1555a9c566 Build: Fix the combination of --disable-xzdec --enable-lzmadec.
In this case "make install" could fail if the man page directory
didn't already exist at the destination. If it did exist, a
dangling symlink was created there. Now the link is omitted
instead. This isn't the best fix but it's better than the old
behavior.

6de61d8721 Update INSTALL.
Add a note about failing "make check". The source of
the problem should be fixed in libtool (if it really is
a libtool bug and not mine) but I'm unable to spend time
on that for now. Thanks to Nelson H. F. Beebe for reporting
the issue.

Add a note about a possible need to run "ldconfig" after
"make install".

54df428799 xz: Rename a variable to avoid a namespace collision on Solaris.
I don't know the details but I have an impression that there's
no problem in practice if using GCC since people have built xz
with GCC (without patching xz), but renaming the variable cannot
hurt either.

Thanks to Mark Ashley.

5876ca27da Docs: Add example program for threaded encoding.
I didn't add -DLZMA_UNSTABLE to Makefile so one has to

ad96a871a1 Windows: Add config.h for building liblzma with MSVC 2013.
This is for building liblzma. Building xz tool too requires
a little more work. Maybe it will be supported, but for most
MSVC users it's enough to be able to build liblzma.

C99 support in MSVC 2013 is almost usable which is a big
improvement over earlier versions. It's "almost" because
there's a dumb bug that breaks mixed declarations after
an "if" statements unless the "if" statement uses braces:

https://connect.microsoft.com/VisualStudio/feedback/details/808650/visual-studio-2013-c99-compiler-bug
https://connect.microsoft.com/VisualStudio/feedback/details/808472/c99-support-of-mixed-declarations-and-statements-fails-with-certain-types-and-constructs

Hopefully it will get fixed. Then liblzma should be
compilable with MSVC 2013 without patching.

MSVC 2013 doesn't like them. Maybe they aren't so good

5ad1effc45 xz: Fix use of wrong variable.
Since the only call to suffix_set() uses optarg
as the argument, fixing this bug doesn't change
the behavior of the program.

dd750acbe2 xz: Make --block-list and --block-size work together in single-threaded.
Previously, --block-list and --block-size only worked together
in threaded mode. Boundaries are specified by --block-list, but
--block-size specifies the maximum size for a Block. Now this
works in single-threaded mode too.

Thanks to James M Leddy for the original patch.

ba413da1d5 xz: Take advantage of LZMA_FULL_BARRIER with --block-list.
Now if --block-list is used in threaded mode, the encoder
won't need to flush at each Block boundary specified via
--block-list. This improves performance a lot, making
threading helpful with --block-list.

The flush timer was reset after LZMA_FULL_FLUSH but since
LZMA_FULL_BARRIER doesn't flush, resetting the timer is
no longer done.

0cd45fc2bc liblzma: Support LZMA_FULL_FLUSH and _BARRIER in threaded encoder.
Now --block-list=SIZES works with in the threaded mode too,
although the performance is still bad due to the use of
LZMA_FULL_FLUSH instead of the new LZMA_FULL_BARRIER.

6b44b4a775 Add native threading support on Windows.
Now liblzma only uses "mythread" functions and types
which are defined in mythread.h matching the desired
threading method.

Before Windows Vista, there is no direct equivalent to
pthread condition variables. Since this package doesn't
use pthread_cond_broadcast(), pre-Vista threading can
still be kept quite simple. The pre-Vista code doesn't
use anything that wasn't already available in Windows 95,
so the binaries should run even on Windows 95 if someone
happens to care.

72975df6c8 Build: Create liblzma.pc in a src/liblzma/Makefile.am.
Previously it was done in configure, but doing that goes
against the Autoconf manual. Autoconf requires that it is
possible to override e.g. prefix after running configure
and that doesn't work correctly if liblzma.pc is created
by configure.

A potential downside of this change is that now e.g.
libdir in liblzma.pc is a standalone string instead of
being defined via ${prefix}, so if one overrides prefix
when running pkg-config the libdir won't get the new value.
I don't know if this matters in practice.

Thanks to Vincent Torri.
