[svn-r10978] Purpose:

   Interim checkin of code changes moving management of the is_dirty flag
into the cache code.


Description:

   Prior to this checkin, management of the is_dirty flag was handled
above the level of the metadata cache.  This can no longer be allowed,
as it introduces a race condition in the proposed fix for a cache
coherency bug in PHDF5.


Solution:

   Move management fo the is_dirty flag to the cache code proper.
Entries are now marked as dirty via a flag on the unprotect call.


Platforms tested:
