d74377e62b liblzma: Fix a memory leak in error path of lzma_index_dup().
lzma_index_dup() calls index_dup_stream() which, in case of
an error, calls index_stream_end() to free memory allocated
by index_stream_init(). However, it illogically didn't
actually free the memory. To make it logical, the tree
handling code was modified a bit in addition to changing
index_stream_end().

Thanks to Evan Nemerson for the bug report.

88d7a7fd15 tuklib_cpucores: Add support for sched_getaffinity().
It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better
than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity()
gives the number of cores available to the process instead of
the total number of cores online.

As a side effect, this commit fixes a bug on GNU/kFreeBSD where
configure would detect the FreeBSD-specific cpuset_getaffinity()
but it wouldn't actually work because on GNU/kFreeBSD it requires
using -lfreebsd-glue when linking. Now the glibc-specific function
will be used instead.

Thanks to Sebastian Andrzej Siewior for the original patch
and testing.

51baf68437 xz: Fix copying of timestamps on Windows.
xz used to call utime() on Windows, but its result gets lost
on close(). Using _futime() seems to work.

74f8dad9f9 liblzma: Disable external SHA-256 by default.
This is the sane thing to do. The conflict with OpenSSL
on some OSes and especially that the OS-provided versions
can be significantly slower makes it clear that it was
a mistake to have the external SHA-256 support enabled by
default.

Those who want it can now pass --enable-external-sha256 to
configure. INSTALL was updated with notes about OSes where
this can be a bad idea.

The SHA-256 detection code in configure.ac had some bugs that
could lead to a build failure in some situations. These were
fixed, although it doesn't matter that much now that the
external SHA-256 is disabled by default.

MINIX >= 3.2.0 uses NetBSD's libc and thus has SHA256_Init
in libc instead of libutil. Support for the libutil version
was removed.

d0e018016b Build: Avoid SHA256_Init on FreeBSD and MINIX 3.
On FreeBSD 10 and older, SHA256_Init from libmd conflicts
with libcrypto from OpenSSL. The OpenSSL version has
different sizeof(SHA256_CTX) and it can cause weird
problems if wrong SHA256_Init gets used.

Looking at the source, MINIX 3 seems to have a similar issue but
I'm not sure. To be safe, I disabled SHA256_Init on MINIX 3 too.

NetBSD has SHA256_Init in libc and they had a similar problem,
but they already fixed it in 2009.

Thanks to Jim Wilcoxson for the bug report that helped
in finding the problem.

8173ff8790 liblzma: Make Valgrind happier with optimized (gcc -O2) liblzma.
When optimizing, GCC can reorder code so that an uninitialized
value gets used in a comparison, which makes Valgrind unhappy.
It doesn't happen when compiled with -O0, which I tend to use
when running Valgrind.

Thanks to Rich Prohaska. I remember this being mentioned long
ago by someone else but nothing was done back then.

2296778f3c xz: Make xz buildable even when encoders or decoders are disabled.
The patch is quite long but it's mostly about adding new #ifdefs
to omit code when encoders or decoders have been disabled.

This adds two new #defines to config.h: HAVE_ENCODERS and
HAVE_DECODERS.

97a3109281 Build: Build LZMA1/2 presets also when only decoder is wanted.
People shouldn't rely on the presets when decoding raw streams,
but xz uses the presets as the starting point for raw decoder
options anyway.

lzma_encocder_presets.c was renamed to lzma_presets.c to
make it clear it's not used solely by the encoder code.

dc6b78d7f0 Build: Fix configure to handle LZMA1 dependency with LZMA2.
Now it gives an error if LZMA1 encoder/decoder is missing

be LZMA2 implicitly enabling LZMA1 but it would need more code.

46d76c9cd3 Build: Don't omit lzma_cputhreads() unless using --disable-threads.

49427ce7ee Fix typo in German translation.
As pointed out by Robert Pollak, there's a typo in the German
translation of the compression preset option (-0 ... -9) help text.
"The compressor" translates to "der Komprimierer", and the genitive
form is "des Komprimierers". The old word makes no sense at all.

608d6f06c9 Update German translation, mostly wrt orthography
Provide an update of the German translation.
* A lot of compound words were previously written with spaces, while
  German orthography is relatively clear in that the components
  should not be separated.
* When referring to the actual process of (de)compression rather than the
  concept, replace “(De-)Kompression” with “(De-)Komprimierung”.
  Previously, both forms were used in this context and are now used in a
  manner consistent with “Komprimierung” being more likely to refer to
  a process.
* Consistently translate “standard input”/“output”
* Use “Zeichen” instead of false friend “Charakter” for “character”
* Insert commas around relative clauses (as required in German)
* Some other minor corrections
* Capitalize “ß” as “ẞ”
* Consistently start option descriptions in --help with capital letters

Acked-By: Andre Noll <maan@tuebingen.mpg.de>

* Update after msgmerge

db190a832c Revert "xz: Use pipe2() if available."
This reverts commit 7a11c4a8e5.
It is a problem when libc has pipe2() but the kernel is too
old to have pipe2() and thus pipe2() fails. In xz it's pointless
to have a fallback for non-functioning pipe2(); it's better to
avoid pipe2() completely.

Thanks to Michael Fox for the bug report.

25263fd9e7 Fix the detection of installed RAM on QNX.

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.
