[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%.
