[svn-r773] Changes since 19981019
----------------------
./src/H5Fistore.c
Improved the hash function so it mixes bits better. This
results in a few percent improvement in raw data chunk cache
efficiency because there are fewer collisions.
./test/chunk.c
Added #define's for chunk preemption `w0' value and number of
slots in cache.
./src/H5B.c
Added some more comments to H5B_insert_helper() and
H5B_remove_helper() and also point to some additional
documentation.
