[svn-r720] Changes since 19980922
----------------------
./src/H5F.c
./src/H5Fprivate.h
./src/H5P.c
./src/H5Ppublic.h
./test/chunk.c
./test/dsets.c
The number of slots in the raw data cache can be queried or
set with H5Pget/set_cache(), which now take an extra argument.
The default number of slots is 521 and the default maximum
size is 1MB.
./src/H5Fistore.c
./src/H5Fprivate.h
Finished optimizations. The cache is now a hash and a linked
list instead of an array. The cpu time on my machine for
H5F_istore_lock() has been cut by 60% and H5F_istore_unlock() by
35%.
