[svn-r11384] Purpose:

    Code cleanup

Description:
    Merge back changes from "compact group" work that improve the
infrastructure of the library and may impact others.  In this round of
merging, that includes:
    - Move datatype allocation into single internal routine, instead of
        duplicated code that was spread out in a dozen or so places.
    - Clean up guts of object header routines (H5O_*) to allow for some of
        the fancieroperations that need to be performed on groups, along with
        some general improvements.
    - Added a new error code
    - Some minor cleanups in other code....

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Linux 2.4
    Mac OS X
