3e551b111b xzless: Update man page slightly.
The xz tool can decompress three file formats and xzless
has always supported uncompressed files too.

b941549573 liblzma: Include the SPDX license identifier 0BSD to generated files.
Perhaps the generated files aren't even copyrightable but
using the same license for them as for the rest of the liblzma
keeps things more consistent for tools that look for license info.

It is built and run only manually so this didn't matter
unless one wanted to regenerate the price_table.c.

76946dc433 Fix SHA-256 authors.
The initial commit 5d018dc035
in 2007 had a comment in sha256.c that the code is based on
Crypto++ Library 5.5.1. In 2009 the Authors list in sha256.c
and the AUTHORS file was updated with information that the
code had come from Crypto++ but via 7-Zip. I know I had viewed
7-Zip's SHA-256 code but back then the C code has been identical
enough with Crypto++, so I don't why I thought the author info
would need that extra step via 7-Zip for this single file.

Another error is that I had mixed sha.* and shacal2.* files
when checking for author info in Crypto++. The shacal2.* files
aren't related to liblzma's sha256.c and thus Kevin Springle's
code in Crypto++ isn't either.

eac2c3c67f Doc: Remove doc/examples_old.
It was good to keep these around in parallel with the newer examples
but I think it's OK to remove the old ones at this point.

97f9ba50b8 liblzma: Check HAVE_USABLE_CLMUL before omitting CRC32 table.

ca9015f4de liblzma: Check HAVE_USABLE_CLMUL before omitting CRC64 table.
If liblzma is configured with --disable-clmul-crc
CFLAGS="-msse4.1 -mpclmul", then it will fail to compile because the
generic version must be used but the CRC tables were not included.

2f1552a91c liblzma: Only use ifunc in crcXX_fast.c if its needed.
The code was using HAVE_FUNC_ATTRIBUTE_IFUNC instead of CRC_USE_IFUNC.
With ARM64, ifunc is incompatible because it requires non-inline
function calls for runtime detection.

1940f0ec28 liblzma: Omit CRC tables when not needed with ARM64 optimizations.
This is similar to the existing x86-64 CLMUL conditions to omit the
tables. They were slightly refactored to improve readability.

761f5b69a4 liblzma: Rename crc32_aarch64.h to crc32_arm64.h.
Even though the proper name for the architecture is aarch64, this
project uses ARM64 throughout. So the rename is for consistency.

Additionally, crc32_arm64.h was slightly refactored for the following
changes:

   * Added MSVC, FreeBSD, and macOS support in
     is_arch_extension_supported().

   * crc32_arch_optimized() now checks the size when aligning the
     buffer.

   * crc32_arch_optimized() loop conditions were slightly modified to
     avoid both decrementing the size and incrementing the buffer
     pointer.

   * Use the intrinsic wrappers defined in <arm_acle.h> because GCC and
     Clang name them differently.

   * Minor spacing and comment changes.

455a08609c liblzma: Refactor crc_common.h.
The CRC_GENERIC is now split into CRC32_GENERIC and CRC64_GENERIC, since
the ARM64 optimizations will be different between CRC32 and CRC64.

For the same reason, CRC_ARCH_OPTIMIZED is split into
CRC32_ARCH_OPTIMIZED and CRC64_ARCH_OPTIMIZED.

ifunc will only be used with x86-64 CLMUL because the runtime detection
methods needed with ARM64 are not compatible with ifunc.

c5f6d79cc9 Build: Add support for ARM64 CRC32 instruction detection.
This adds --enable-arm64-crc32/--disable-arm64-crc32 (enabled by
default) for using the ARM64 CRC32 instruction. This can be disabled if
one knows the binary will never need to run on an ARM64 machine
with this instruction extension.

849d0f282a Speed up CRC32 calculation on ARM64
The CRC32 instructions in ARM64 can calculate the CRC32 result
for 8 bytes in a single operation, making the use of ARM64
instructions much faster compared to the general CRC32 algorithm.

Optimized CRC32 will be enabled if ARM64 has CRC extension
running on Linux.

footer. The license is also copied to statisfy the copyright and so the
link in the documentation can be local.
