gtk2-perl thread safe

[Ross McFarland <rwmcfa1 neces com>]

gtk2-perl should now be able to run safely with perl ithreads. the
changes are confined to Glib. using the new threadsafe facility,
Glib::Object->set_threadsafe, in conjunction with the gdk x locking
mechinsms you should now be able to write truly threaded gtk2-perl apps.
documentation and tests are yet to come. 

muppet committed part of the fix this morning and i put in the second
portion a bit ago. it's by no means safe to run this in production at
this point. there should be an unstable set of releases with this in it
before too long.

* GObject.xs: code to allow gobject tracking which and
threadsafeness. needs lots of testing, documentation, and needs a way to
tell if thread support was compiled into perl. right now it's enabled
(if compiled in) by calling Glib::Object->set_threadsafe.
