[svn-r15388] Description:

	Convert object header cache client to use the new metadata journaling
cache, which included adding a new client for handling continuation chunks.
Added "real" protect calls around modifying chunks in object headers.

	Switched a few more metadata cache library API routines to drop the
file pointer, when it is not needed (pinning/unpinning entries, etc.)

	Fixed bug in journaling cache handling of 'image_len' callbacks and
also changed cache to retry deserializing entries when the entry's size is
larger than the speculative size initially tried.

	Retrying for 'image_len' callbacks has problems with the 'multi' VFD,
so the h5dump and FORTRAN 'multi' tests are commented out, until the changes to
the 'multi' VFD from the file free space branch are brought back into the
trunk.

	Currently, the 'h5recover' tool has a bug which requires it to be run
twice before replaying the journal "sticks".  However, this is from an earlier
checkin, since the code in the branch already has this behavior... :-(

Tested on:

        FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode
