Original commit message from CVS:
Cleaned up INFO system some more, added API to select categories, modified
the printout function to print cleanly for GST_INIT info (the default min)
and spew function:line debug_string [element] for everything else.
Eventually could make even that configurable easily enough, just check
against another bitmap instead of checking for == GST_INIT.
