    Xlib/XCB: Fix _XReadEvents to always enqueue a new event, even if an error occurs
    
    Commit c337f9de7cfd89f983f83956b7457a274dd412f3 broke the invariant that
    _XReadEvents always enqueues at least one event even if an error occurred,
    because the one call to xcb_wait_for_event would then return an error, not an
    event, and nothing else ensured that process_responses would obtain an event.
    Fix this by reverting most of c337f9de7cfd89f983f83956b7457a274dd412f3 and
    f417570735aac865eb6b576d1ea76b5bfcd8573b and implementing the correct fix.  In
    process_responses, wait_for_first_event now serves as a flag, cleared when
    actually handling an event.
