Remove hack forcing MPEG1 video to be treated as MPEG2
This hack was added to fix #287, which was a problem with XvMC decoding.
It makes no sense today, and actually break genuine MPEG1 videos.

Fixes #12160

Only use VDPAU hwaccel API for mpeg container
The use of VDPAU hwaccel API was an attempt to fix #11377. However, the underlying problem is a FFmpeg libavformat bug (https://trac.ffmpeg.org/ticket/2915).

FFmpeg 1.2's VDPAU hwaccel is clearly unstable. 24fps AVI would play at half that rate, cause crashes with nouveau or visual distortion with AMD

As the aim is only to fix #11377, only enable the hwaccel API for the mpeg container.

Add a "vdpauhwaccel" setting override to completely disable VDPAU hwaccel under all circumstances

Fixes #12162
