Quincey Koziol a6ce3d4e45 [svn-r29850] Description: 
Bring H5DOappend(), H5P[s|g]et_object_flush_cb, and H5P[s|g]et_append_flush
from revise_chunks branch to trunk.  Brings along updated metadata cache
entry tagging, and the internal object flush routine.

Tested on:
    MacOSX/64 10.11.4 (amazon) w/serial, parallel & production
    (h5committest forthcoming)
