Lasse Collin 1238381143 xz: Add support for sandboxing with Capsicum.
The sandboxing is used conditionally as described in main.c.
This isn't optimal but it was much easier to implement than
a full sandboxing solution and it still covers the most common
use cases where xz is writing to standard output. This should
have practically no effect on performance even with small files
as fork() isn't needed.

C and locale libraries can open files as needed. This has been
fine in the past, but it's a problem with things like Capsicum.
io_sandbox_enter() tries to ensure that various locale-related
files have been loaded before cap_enter() is called, but it's
possible that there are other similar problems which haven't
been seen yet.

Currently Capsicum is available on FreeBSD 10 and later
and there is a port to Linux too.

Thanks to Loganaden Velvindron for help.

Lasse Collin 29a087fb5a Fix bugs and otherwise improve ax_check_capsicum.m4.
AU_ALIAS was removed because the new version is incompatible
with the old version.

It no longer checks for <sys/capability.h> separately.
It's enough to test for it as part of AC_CHECK_DECL.
The defines HAVE_CAPSICUM_SYS_CAPSICUM_H and
HAVE_CAPSICUM_SYS_CAPABILITY_H were removed as unneeded.
HAVE_SYS_CAPSICUM_H from AC_CHECK_HEADERS is enough.

It no longer does a useless search for the Capsicum library
if the header wasn't found.

Fixed a bug in ACTION-IF-FOUND (the first argument). Specifying
the argument omitted the default action but the given action
wasn't used instead.

AC_DEFINE([HAVE_CAPSICUM]) is now always called when Capsicum
support is found. Previously it was part of the default
ACTION-IF-FOUND which a custom action would override. Now
the default action only prepends ${CAPSICUM_LIB} to LIBS.

The documentation was updated.

Since there as no serial number, "#serial 2" was added.

Lasse Collin 6e845c6a3e Add m4/ax_check_capsicum.m4 for detecting Capsicum support.
The file was loaded from this web page:
https://github.com/google/capsicum-test/blob/dev/autoconf/m4/ax_check_capsicum.m4

Thanks to Loganaden Velvindron for pointing it out for me.

Lasse Collin 3717885f9e Bump version to 5.3.0alpha and soname to 5.3.99.
The idea of 99 is that it looks a bit weird in this context.
For new features there's no API/ABI stability in devel versions.

Lasse Collin 25263fd9e7 Fix the detection of installed RAM on QNX.
The earlier version compiled but didn't actually work
since sysconf(_SC_PHYS_PAGES) always fails (or so I was told).

Thanks to Ole André Vadla Ravnås for the patch and testing.

Lasse Collin 4c544d2410 Fix CPU core count detection on QNX.
It tried to use sysctl() on QNX but
  - it broke the build because sysctl() needs -lsocket on QNX;
  - sysctl() doesn't work for detecting the core count on QNX
    even if it compiled.

sysconf() works. An alternative would have been to use
QNX-specific SYSPAGE_ENTRY(num_cpu) from <sys/syspage.h>.

Thanks to Ole André Vadla Ravnås.

Lasse Collin 7f0a4c50f4 xz: Make arg_count an unsigned int to silence a warning.
Actually the value of arg_count cannot exceed INT_MAX
but it's nicer as an unsigned int.

Lasse Collin 117d962685 liblzma: Fix a compression-ratio regression in LZMA1/2 in fast mode.
The bug was added in the commit
f48fce093b and thus
affected 5.1.4beta and 5.2.0. Luckily the bug cannot
cause data corruption or other nasty things.

Lasse Collin ae984e31c1 xz: Fix the fcntl() usage when creating a pipe for the self-pipe trick.
Now it reads the old flags instead of blindly setting O_NONBLOCK.
The old code may have worked correctly, but this is better.

Lasse Collin d935b0cdf3 tuklib_cpucores: Use cpuset_getaffinity() on FreeBSD if available.
In FreeBSD, cpuset_getaffinity() is the preferred way to get
the number of available cores.

Thanks to Rui Paulo for the patch. I edited it slightly, but
hopefully I didn't break anything.

Lasse Collin b9a5b6b7a2 Add a few casts to tuklib_integer.h to silence possible warnings.
I heard that Visual Studio 2013 gave warnings without the casts.

Thanks to Gabi Davar.

Thanks to Torsten Rupp for reporting this. I had

Lasse Collin 4170edc914 xz: Don't fail if stdout doesn't support O_NONBLOCK.
This is similar to the case with stdin.

Thanks to Brad Smith for the bug report and testing
on OpenBSD.

Lasse Collin f0f1f6c723 xz: Don't fail if stdin doesn't support O_NONBLOCK.
It's a problem at least on OpenBSD which doesn't support
O_NONBLOCK on e.g. /dev/null. I'm not surprised if it's
a problem on other OSes too since this behavior is allowed
in POSIX-1.2008.

The code relying on this behavior was committed in June 2013
and included in 5.1.3alpha released on 2013-10-26. Clearly
the development releases only get limited testing.

Lasse Collin d2d484647d Tests: Don't hide unexpected error messages in test_files.sh.
Hiding them makes no sense since normally there's no error
when testing the "good" files. With "bad" files errors are
expected and then it makes sense to keep the messages hidden.

Lasse Collin aae6a6aeda Update Solaris notes in INSTALL.
Mention the possible "make check" failure on Solaris in the
Solaris-specific section of INSTALL. It was already in
section 4.5 but it is better mention it in the OS-specific
section too.

Lasse Collin 6060f7dc76 Bump version and soname for 5.2.0.
I know that soname != app version, but I skip AGE=1
in -version-info to make the soname match the liblzma
version anyway. It doesn't hurt anything as long as
it doesn't conflict with library versioning rules.

Lasse Collin 0152f72bf6 Windows: Update the build script and README-Windows.txt.
The 32-bit build is now for i686 or newer because the
prebuilt MinGW-w64 toolchains include i686 code in the
executables even if one uses -march=i486.

The build script builds 32-bit SSE2 enabled version too.
Run-time detection of SSE2 support would be nice (on any OS)
but it's not implemented in XZ Utils yet.
