[omxplayer] Allow small audio packets to be concatenated to make better use of audio fifo

Some audio codecs produce small packets which causes a high overhead when submitting to GPU, and doesn't make full use of GPU side buffering.
TrueHD in particular can produce packets with 40 samples (so 1200 packets per second) which causes very high overhead.

What this aims to do is to concatenate audio packets until they approach the ideal audio packet size,
and then deal with the awkardness of concatenated planar formats.
[omxplayer] Use media time for determing audio delay and cache time

I've also added caching to the call to OMXMediaTime as the GPU round trip is expensive when called too frequently
Use pass by ref to construct DVDMsgType

This saves doing an extra copy for each call to the constructor, the worst one probably being the PVR channel changes at 168 bytes each.

[Pydocs] Add info for Player and RenderCapture

1) Added information in comments to be pulled into PyDocs describing the
shortcomings when calling xbmc.player.getPlayingFile() for LiveTV.
Specifically that pvr:// url's are not translated into usable filenames
or streams.
2) Added information to xbmc.CapturePlayer regarding the functions
getHeight() and getWidth() which return 0 prior to calling
CapturePlayer.capture(). Also added that getAspectRatio() may be called
prior to issuing a capture() request.
