SHA256 would make libarchive based application to give:
archive_read_extract(): Lzma library error: Corrupted input data
(Internally this is LZMA_DATA_ERR)
However, the libmd version of SHA256 is supposed to give same result
as the bundled version do, and xz(1) is not affected.
As a precaution, revert the SHA256 portion of r281316 for now until
we figure out why it breaks libarchive interoperability as we can't
yet rule out this change have introduced an ABI breakage.
- Update xz to 5.2.1, where the most visible change is that it
fixed a compression-ratio regression in fast mode LZMA1 and
LZMA2 and used cpuset_getaffinity() for CPU cores detection.
- Make liblzma use the base system SHA256 implementation instead of
the bundled one.
- Additional annotation in config.h for FreeBSD specific tweaks.
- Refresh symbols in XZprivate_1.0 to reflect reality.
Relnotes: yes
MFC after: 1 month (TBD)
This brings support for multi-threaded compression. This brings close
N times faster compression where N is the number of CPU cores.
Because of this, liblzma now depends on libthr.
Soon libarchive will be modified to use the new lzma API.
Thanks to antoine@ for the exp-run.

memory access functions to the ones used for aligned accesses, so do
not define TUKLIB_FAST_UNALIGNED_ACCESS.
