[svn-r19006] Purpose: Improve performance of the the chunk cache
Description:
Previously, the chunk cache would, when looking for a chunk, alwaylook for the
chunk in the b-tree before checking the cache. Reworked the functions that
look up chunks to always check the cache first and avoid the b-tree lookup if
the chunk is in cache.
Tested: jam, linew, amani (h5committest)
