dvdplayer: move extradata cleanup to CDVDDemuxStream destructor
dvdplayer: keep temporary stream pointer in ffmpeg AddStream
dvdplayer: keep ffmpeg demuxer indexes in continous order
demuxer ffmpeg: handle pmt changes
GUIEpgGridContainer: split Render() into Process() / Render()
GUIEpgGridContainer: get rid of GetRulerCacheOffsets() method which is just duplicated GetProgrammeCacheOffsets()
GUIEpgGridContainer: get rid of unused now (and never should be used) m_renderTime
GUIEpgGridContainer: fix memory freeing for ruler items
GUIEpgGridContainer: fix memory freeing for programme items

[players] Fix dts time after seek

DllAvCodec: map avcodec_encode_audio2
Improve compatibility with C++11 (Visual Studio 2012, Intel C++ compiler 13.0)
DllAvCodec: map avcodec_fill_audio_frame
DllAvCodec: map avcodec_free_frame.

This makes xbmc require FFmpeg 1.0
AEEncoderFFmpeg: switch to avcodec_encode_audio2 and convert input audio to a format accepted by the encoder if AE does not handle it. Fixes transcoding to AC3 for passthrough (e.g. HDMI).

Without this, with ffmpeg 1.1 and later, xbmc segfaults when trying to transcode
to AC3.

It would be better to have AE to support planar formats but this fallback will be useful in case there are even other audio formats introduced in FFmpeg and is simpler for now.
[rbp] Remove unnecessary gl ifdef

I'm not sure why this was originally added.
I couldn't think of a reason why the Pi would want things done differently here,
so I tried without the ifdef. I can't see any difference in behaviour,
so I think we're better off removing it.
[musicdb] fix: unchecked access to albumartists/artists causes us to crash when they're empty
