[svn-r18910] Description:

	Remove 'size' parameter from H5AC2_set()/H5C2_insert_entry(), to align
better with trunk.  Use the 'image_len' cache client callback to retrieve the
size of an inserted entry.  Also, add flags to the cache client class structure,
to indicate several client behaviors: speculative loads & compressed storage
on disk (which were previously dependent on the 'image_len' callback only
being used to detect size changes during load (deserialize) operations).

Tested on:
        Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in debug mode
        Mac OS X/32 10.6.3 (amazon) in debug mode
        Mac OS X/32 10.6.3 (amazon) w/C++ & FORTRAN, w/threadsafe,
                in production mode
