416e719bea More archaic-checksum improvements. This makes the len vars clearer 
and ensures that only the flist code gets the 2-byte digest len.

de94193353 Remove bypassed checksums in --inplace to improve speed. 
When checking a checksum that refers to a part of an --inplace file that
has been overwritten w/o getting SUMFLG_SAME_OFFSET set, we remove the
checksum from the list.  This will speed up files that have a lot of
identical checksum blocks (e.g. sequences of zeros) that we can't use
due to them not getting marked as being the same.  Patch provided by
Michael Chapman.

adc2476fa2 Output numbers in 3-digit groups by default (e.g. 1,234,567). 
Also improved the human-readable output functions, including
adding the ability to output negative numbers.

951e826b75 Added the --info=FLAGS an --debug=FLAGS options, which allows

a2c770dc21 Switching over to a dynamic hash method for really large files. 
This code has been reported to be better for large files than the
file-chunking code that was included in pre3.

often when overwriting a shorter file.

0f78b81511 - Updated the address for the FSF in the opening comment. 
- Standardized the format of the opening comment, including adding a
  brief description of what's in the file for those that lacked it.
- Added some missing copyright lines.
- Some minor whitespace tweaks (in a few of the files).

48cce779a2 Decided to drop the dynamically sized hash table for now. This was 
due to timing tests showing that the per-byte modulus calculation
slowed down regular sized files.  Kept the other improvements
because they lessened our memory use and actually sped up the code.

900cfcb584 - Fixed a problem with the new gettag2() macro by getting rid of the 
need for it.
- Fixed a really old bug in the verbose output where it would output
  the wrong sum value (off by one).
- Renamed the tag_hit variables & debug output to hash_hit.

d9bca0c32f This is Shachar Shemesh's patch for making the hash-table code 
work better with large files.  I further modified it to eliminate
the extra level of indirectness (and the qsort()), which saves
memory.

information during the checksum scan of the already-sent data.

0394e34a69 Moved the end_progress() call from match.c to sender.c so that we 
report progress on 0-length files when pushing files (the receiver
already called it, so we already produced progress on a 0-length
file when pulling).
