Rename the lists release_queue to release_list and event_list to
wait_list.
The prior names release_queue and event_list were ambiguous: in both are event-
like vblanks which can be removed from the lists in random order. In the
release_queue can be flips that are already released but still wait for the
sync or frame callback but normally the release comes later. In the event_list
are queued events waiting for a later msc.

These events aren't reachable after xwl_present_cleanup, so they're
leaked if we don't free them first.
This requires storing the pixmap pointer in struct xwl_present_window.
Luckily, the buffer pointer isn't used for anything, so just replace
that.
v2:
* Bump pixmap reference count in xwl_present_flip and drop it in
xwl_present_free_event, fixes use-after-free in the latter due to the
pixmap already being destroyed.

We were only calling xwl_present_unrealize_window for the toplevel
window, but the list can contain entries from child windows as well,
in which case we were leaving dangling pointers to freed memory.
