[svn-r18862] Description:

	Add 'get_load_size' client callback to determine the image size for
reading a metadata cache entry from the file.

	Remove the 'size' parameter from the H5[A]C_protect() calls.

	General cleanups to align with code on trunk.

Tested on:
        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
        Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in production mode
