[svn-r22708] Description:

    Bring r22707 from trunk to 1.8 branch:

    Bring back some more cleanups from the plist_encode_decode branch, clean up
some formatting and compiler errors, and add a few more property comparison
routines that we've skipped implementing in the past.

Tested on:
    Mac OSX/64 10.7.4 (amazon) w/debug
    (Too minor to require h5committest)
