[svn-r9022] Purpose: Optimization of the cache code in H5C.
Description: Cache was running too slowly.
Solution: Added a hash table for indexing. Retained the tree, but
only for dirty entries. As we need to flush dirty entries
in increasing address order, this is sufficient.
Updated statistics collection code for the above.
Converted a number of local functions into macros to avoid
the function call overhead.
Added code to disable the clean and dirty LRU lists in serial
mode.
Updated test code to account for the above changes.
Platforms tested: h5committested + serial, parallel, and fp on Eirene.
Misc. update:
