This updates our in-tree copy of libvpx to the v1.3.0 git tag (2e88f2f2ec777259bda1714e72f1ecd2519bceb5) libvpx 1.3.0 adds support for VP9. VP9 support is built but not yet exposed with this commit. Our update.sh script is replaced with update.py that can update the build system to a given git commit. - checkout out upstream git - create platform dependend config files - add/remove changed libvpx files - update moz.build - warn about new build categories in libvpx

* VP8 is vpx's newest video compression algorithm that uses motion
|
|
* compensated prediction, Discrete Cosine Transform (DCT) coding of the
|
|
* prediction error signal and context dependent entropy coding techniques
|
|
* based on arithmetic principles. It features:
|
|
* - YUV 4:2:0 image format
|
|
* - Macro-block based coding (16x16 luma plus two 8x8 chroma)
|
|
* - 1/4 (1/8) pixel accuracy motion compensated prediction
|
|
* - 4x4 DCT transform
|
|
* - 128 level linear quantizer
|
|
* - In loop deblocking filter
|
|
* - Context-based entropy coding
