Anssi Hannula 8f4a5d225c dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRA 
DTS-HD HRA streams do not always have an XBR extension in the extension
substream. Instead they can have only XXCh and X96 extensions in
there and still be considered DTS-HD HRA.

This is also confirmed with Onkyo TX-SR607 receiver which recognizes
such a stream as HiRes Audio.

Jason Garrett-Glaser f14bdd8e75 H.264: Partially inline CABAC residual decoding 
Improves CABAC performance about ~1.2%.

Trick originates from x264 and has also been used in ffvp8.  It's useful because
coded block flags are usually zero, so it helps to have the early termination
inlined into the main function.

Frank Barchard 925aa96915 Second hunk from secrity fix from google. 
The hunk is not fully understood but it just makes a check tighter so its
safer for us to apply until it is fully understood.

Might fix issue 2550 (and Chrome issue 68115 and unknown CERT issues).
Our bugtracker issue though should stay open until this has been fully
investiagted
