The _clutter_process_event() function may get called while already
servicing a _clutter_process_event() invocation (eg. when generating
ENTER events before emitting TOUCH_BEGIN).

In these cases clutter_get_current_event() would return NULL after
the inner call to _clutter_process_event() has finished, thereafter
making the current event inaccessible during the remaining portion
of the outer event emission.

By stacking the current events in ClutterMainContext instead of
simply replacing them we do not lose track of the real current event.

Also update clutter_get_current_event_time() to be consistent from a
reentrancy perspective.
