* commit 'c923cdad6e515c842f3795a5b6d754ad94021e09':
HDFFV-10571: Minor format changes.
HDFFV-10571: Minor change - reformatting the error check.
HDFFV-10571: Minor change - adding the error check right after decoding of chunk dimension for safeguard.
HDFFV-10571: Minor change - revised the comment to be clearer.
HDFFV-10571 Divided by Zero vulnerability. Minor fix: I added an error check to make sure the chunk size is not zero.

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.

The function H5VM_power2up() returns the next power of 2 for n.
When n exceeds 2^63, it overflows and becomes 0 causing the infinite looping.
The fix ensures that the function checks for n >= 2^63 and returns 0.

More minor whitespace cleanup
Fixed a minor comment typo in H5R.c
* Reverted removal of H5I_REFERENCE to avoid breaking binary compatibility. * Added a quick H5I_REFERENCE smoke check to test_misc19() in tmisc.c.
Added missing free() call to test_misc19().
Purged the unused H5I_REFERENCE from the library.

Fix for HDFFV-10160 Modifications to fix the assertion/abort failure when the application does not close the file.
Fixed a bug in autotools Fortran processing where a test for the presence of a C long double type always returned true.
Updated the --enable-debug/production handling in configure.ac so that it more reliably indicates that the configure option can no longer be used. Previously, using --enable-debug="", etc. would not trigger an error (even though such usage is unlikely).
Added awk processing to remove extraneous whitespace from H5_ flags in configure.
