d474f2986e Improve performance of file_checksum() 
Previously files were hashed in blocks of CSUM_CHUNK (64) bytes. This
causes significant overhead. The CSUM_CHUNK define cannot be changed as
md5.c depends on it, but there is no obvious reason to use it in
file_checksum(). By using CHUNK_SIZE (32 kB) instead, in some test
cases throughput more than doubles.

4f92fd8ddd Some more checksum improvements 
- Add/improve --debug=CSUM2 messages.
- Add an "xxh64" alias for "xxhash" name because we should be
  getting a few more xxhash variations in the future.
- Tweak the matching code to handle entries that have multiple
  names.
- Tweak some of the vars/defines.

5fa4209ca0 AVX2 optimized version of get_checksum1() for x86-64 
Additionally restructures build switches and defines from SSE2 to SIMD,
to allow potential reuse should patches become available with SIMD
instructions for other processor architectures.

(Some minor tweaks of Jorrit's patch to avoid requiring GNU make and to
avoid C++ comments in .c files.)

4f6c8c6652 Checksum negotiation & more bits for compat_flags 
- Add checksum negotiation to the protocol so that we can easily add new
  checksum algorithms and each will be used when both sides support it.
- Increase the size of the compat_flags value in the protocol from a
  byte to an int.

70c6b408dc SSE2/SSSE3 optimized version of get_checksum1() for x86-64 
Requires compilation using GCC C++ front end, build scripts have been
modified accordingly. C++ is only used when the optimization is enabled
(g++ as compiler, x86-64 build target, --enable-sse2 is passed to
configure).

(Wayne made a few tweaks, including making it disabled by default.)

c5fabfb068 Set Copyright years and make them easier to update 
I replaced git-set-file-times with an improved version that I wrote
recently (in python3). A new script uses it to figure out the
last-modified year for each *.[ch] file and updates its copyright.
It also puts the latest year into the latest-year.h file for the
output of --version.
