phase 1 of somewhat major rearrangement of PERL_OBJECT stuff
(objpp.h is gone, embed.pl now does some of that); objXSUB.h
should soon be automated also; the global variables that
escaped the PL_foo conversion are now reined in; renamed
MAGIC in regcomp.h to REG_MAGIC to avoid collision with the
type of same name; duplicated lists of pp_things in various
places is now gone; result has only been tested on win32
