This hopefully helps on scrollin bigger playlists as view is not always
back on top.

This fixes playback for wall-e bluray (and maybe others)

Should be now the same as it would be in fullscreen.

Avoid repeating the same implementation several times:
 incorrectly (switcher and mux didn't lock)
 redundantly (avcodec_register_all can be called several times)

Move libavXXX init at the top of a few functions, just in case.

Check uses of vlc_avcodec_(un)lock and factorize

Also, this commit reenables resize to native video size, if video starts.

Now, the vout should have the same functionality as all the other. At least in
fullscreen, zoom should work now like in other vouts.
Furthermore, this commit tells the core our current size on every resize,
so we get a sharp osd screen every time. For zoom / ar / crop / size handling,
the code was simplified in order to remove duplicated lines and to make the
code more readable.

Should also close #307.
