3828eb8519 libfdk-aac: Relicense the library wrappers to 2-clause BSD 
This should make it possible for Fraunhofer to contribute to these
wrappers - they didn't want to contribute to code under LGPL2.1 with
the "or any later version" clause (which allowed using the code
under the LGPL3 license).

15fa856b82 libfdk-aacenc: Enable 7.1 channel encoding 
7.1(wide) and 7.1(wide-side) channel layouts are supported in
fdk-aac since the 0.1.3 release.

The earlier versions of fdk-aac didn't include any library
version defines in the public headers, thus checking for
the AACENCODER_LIB_VL0 define is enough to know that we're
building against a new enough version of fdk-aac.

This change includes contributions by Tim Walker,
Michael Niedermayer and Timothy Gu.

ed4b757177 dxva2_h264: add a workaround for old Intel GPUs 
Old Intel GPUs expect the reference frame index to the actual surface,
instead of the index into RefFrameList as specified by the spec.

This workaround should be set when using one of the "ClearVideo" decoder
devices.

2fcef90bee dxva2_h264: set the correct ref frame index in the long slice struct 
The latest H.264 DXVA specification states that the index in this
structure should refer to a valid entry in the RefFrameList of the picture
parameter structure, and not to the actual surface index.

Fixes H.264 DXVA2 decoding on recent Intel GPUs (tested on Sandy and Ivy)
