[svn-r27768] Description:

    Complete revamp of package initialization/shutdown mechanism in the library.
Each package now has a single init/term routine.

    This new way should avoid packages being re-initialized during library
shutdown and is also be _much_ more proactive about giving feedback for
resource leaks internal to the library.

    Introduces a new "module" header file for packages in the library
(e.g src/H5Fmodule.h) which sets up some necessary package configuration macros
for the FUNC_ENTER/LEAVE macros.  (The VFL drivers have their own slightly
modified version of this header, src/H5FDdrvr_module.h)

    Also cleaned up a bunch of resources leaks all across the library and tests,
along with addressing many warnings, as I encountered them.

Tested on:
    MacOSX/64 10.10.5 (amazon) w/serial & parallel
    Linux/64 3.10.x (kituo) w/serial & parallel
    Linux/64 2.6.x (ostrich) w/serial
