Add dtrace and systemtap support for gobject
This adds static markers and systemtap tapsets for: * type creation * object lifetimes (creation, ref, unref, dispose, finalize) * signal creation and emission Signal emissions and finalization marker have a corresponding *_end (or *-end in dtrace) version that is when the corresponding operation is finished. https://bugzilla.gnome.org/show_bug.cgi?id=606044
