Comment:

 (In [11616]) Fixes #2552. Sets the proper bitrate in the RingBuffer after
 it is reset by an OpenFile.

 We add a GetRawBitrate() method to DecoderBase which returns the current
 estimated bitrate of the video if played at normal speed, and add calls in
 the NVP which calls RingBuffer::UpdateRawBitrate() with this value shortly
 after either of the two OpenFile calls in the NVP.

 This should resolve some of the issues with prebuffer pauses after a
 LiveTV program change with HDTV streams on slower frontends.
