Before, a VO could easily refuse to respond to VOCTRL_REDRAW_FRAME, which means the VO wouldn't redraw OSD and window contents, and the player would appear frozen to the user. This was a bit stupid, and makes dealing with some corner cases much harder (think of --keep-open, which was hard to implement, because the VO gets into this state if there are no new video frames after a seek reset). Change this, and require VOs to always react to VOCTRL_REDRAW_FRAME. There are two aspects of this: First, behavior after a (successful) vo_reconfig() call, but before any video frame has been displayed. Second, behavior after a vo_seek_reset(). For the first issue, we define that sending VOCTRL_REDRAW_FRAME after vo_reconfig() should clear the window with black. This requires minor changes to some VOs. In particular vaapi makes this horribly complicated, because OSD rendering is bound to a video surface. We create a black dummy surface for this purpose. The second issue is much simpler and works already with most VOs: they simply redraw whatever has been uploaded previously. The exception is vdpau, which has a complicated mechanism to track and filter video frames. The state associated with this mechanism is completely cleared with vo_seek_reset(), so implementing this to work as expected is not trivial. For now, we just clear the window with black.
