HDFFV-10601: Adding the new hdf5/tools/test/perform/chunk_cache.c to MANIFEST.
HDFFV-10601: Some compiler doesn't support clock_gettime(). So I changed to use gettimeofday (HDgettimeofday in the HDF5 library).
* commit 'cd13d24e5140578a880aebe4e2d8b899179d0870':
HDFFV-10601: I added error checking to the HDF5 functions.
HDFFV10601: Adding performance test to verify the improvement.
HDFFV-10601: I changed to a better way to calculate the number of chunks in a dataset.

1. H5D__chunk_hash_val: When the number of chunks in the fastest changing dimension is larger than the number of slots in the hash table, H5D__chunk_hash_val abandons the normal hash value calculation algorithm and simply uses the scaled dimension. This will cause chunks a selection that cuts across chunks in dimensions other than the fastest changing to all have the same hash value, and they will therefore always evict each other from the cache, having an obvious major performance impact. Eliminated the check for the number of slots in this function and always use the full algorithm.
2. H5D__chunk_init: When the scaled dimensions (number of chunks in each dimension) are calculated in H5D__chunk_init, a simple divide ("/") operator is used with the dataset size in elements and the chunk size in elements. While this is fine when the dataset size is an exact multiple of the chunk size, in other cases, since "/" rounds down, it results in a scaled dimension one less than it should (it ignores the partial edge chunk). This has trickle down effects on hash value calculation that can cause excess hash value collisions and therefore performance issues. Changed the calculation to (((dataset_size - 1) / chunk_size) + 1).
Tested the build with Autotool and CMake.
