Quincey Koziol 7143164de9 [svn-r22608] Description:
Switch propert list/class iteration from internal to external form of
iteration, cleaning up and simplifying the code a bit.

    Bring other general improvements from plist_encode_decode branch back to
trunk.

    Clean up many warnings.


Tested on:
    Mac OSX/64 10.7.4 (amazon) w/gcc 4.7, debug and C++ & FORTRAN
    (too minor to require h5committest)
