Description:
    Misc. cleanups to make the code 64-bit hid_t clean.

    Remove code for wrapping hid_t values.

    Revert changes to H5Fget_numobjects and H5Fget_obj_ids, it's better to
cast H5F_OBJ_ALL when needed.

Tested on:
    Mac OSX/64 10.9.3 (amazon) w/C++, FORTRAN, gcc 4.9 & parallel
    (will be h5committested before merge to trunk)
