This requires bleeding-edge libavcodec.

The acceleration plugin now returns the expected pixel format instead
of checking it. That way, the avcodec module can check it directly.

This works as long as each acceleration plugin supports only one pixel
format (otherwise a table would be required).

This is a manual backport of commit-id: 1962cd3095652e676cea7830da863cc6f2b621d6

It is really 2.0.7 now.

Remove the dependency on video_output/opengl.{c,h} and cleanup an unused variable.

This reverts commit 91f15717.

Conflicts:
	modules/codec/avcodec/vaapi.c
	src/video_output/video_output.c

Rename functions and structures.

Reuse as much code as possible from vaapi-xcb implementation. Most of
the routines can be shared and are placed inside common.{c,h}. The
video output has been moved to modules/video_output/vaapi/, but is
still build from modules/codec/avcodec/Modules.am. This is because
the video output shares the same libva connection as the decoder.
Since this is mandatory for some GPU implementations such as AMD Fusion.

Ignore wholly translucent rows at the top and bottom of the subtitle page

Only create an overlay large enough for the remaining rows and only only ask
zvbi to render those rows.

One happy side effect is that now --vbi-text no longer outputs header text
for some teletext streams (although --vbi-text is still unusable imho).

Reducing the size of the overlay allows stutter free playback of teletext
subtitles on significantly slower hardware.
