[svn-r11686] Purpose:

    New feature

Description:
    Add in baseline "object copy" code from Peter [in the form of a new API
routine: H5Gcopy()].  There's still some work to do (like handling variable-
length datatypes and possibly support for references) and it hasn't been tested
on mounted files yet, but the core functionality is there and working
correctly.

    I've also got a set of patches to update the 1.6 branch with tweaks to
keep the branches mostly in sync, but Elena will kill me if I import them
before the 1.6.5 release is out... :-)

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    h5committested
