glib: Add more GLib main context SystemTap and DTrace probes
Expand the set of available probes, and add a few more output parameters to some of the existing ones to make them more useful. I do not know if this breaks any existing stability guarantees for GLib’s SystemTap tapset, as it is effectively just adding some more local variables in the user’s probe. https://bugzilla.gnome.org/show_bug.cgi?id=759813
