Make split condition depend on ~0, not 0.
Otherwise we could end up splitting on one-byte blocks, which is pretty
dumb.

Report the block size when splitting each block.

Add a README

Add some comments so nobody thinks I think fgetc/fputc are fast.

Add a comment to stupidsum_add() so people don't think I'm an idiot.
Yes, I know shift-and-xor is a supremely lame algorithm.

Rename hsplit/hjoin to hashsplit/hashjoin.

Add a trivial hjoin, the reverse of hsplit.

Aha, fixed a bug causing the split points not to resync.

Actually hash stuff, and add a basic 'make test'.
Unfortunately the test fails: after the first difference, it never manages
to resync.

Extremely cheesy initial implementation of rolling-sum-based splitting.
The checksum algorithm is crap, and we don't actually generate the output
files yet, so I'm guessing it's still junk.
