[svn-r7460] Purpose:

    Update

Description:
    Added extra parameter to the H5AC_protect() function that indicates
    if the cache being asked for is going to be written to or just read
    from. Those AC_protect calls that were H5AC_find calls are now
    read-only. The rest are writes.

Platforms tested:
    Linux (h5committest not needed due to size and small impact)

Misc. update:
