[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.
