Gets the #GMainContext with which the source is associated.
You can call this on a source that has been destroyed, provided
that the #GMainContext it was attached to still exists (in which
case it will return that #GMainContext). In particular, you can
always call this function on the source returned from
g_main_current_source(). But calling this function on a source
whose #GMainContext has been destroyed is an error.
