bdiff: switch to lyhash
lyhash is a very simple and fast hash function that had the fewest
hash collisions on a 3.9M line text corpus and 190k line binary corpus
and should have significantly fewer collisions than the current hash
function.

bdiff: simple splitlines optimization
Christoph Spiel <cspiel@freenet.de> [Thu, 27 Sep 2007 23:57:57 -0500] rev 5363
I have spotted the biggest bottleneck in "bdiff.c". Actually it was
pretty easy to find after I recompiled the python interpreter and
mercurial for profiling.
In "bdiff.c" function "equatelines" allocates the minimum hash table
size, which can lead to tons of collisions. I introduced an
"overcommit" factor of 16, this is, I allocate 16 times more memory
than the minimum value. Overcommiting 128 times does not improve the
performance over the 16-times case.
