From: Zhao Zhili <zhilizhao at tencent.com>

v2:
1. It works with x265 streams
2. Remove the requirement on SEI. SEI alpha channel information is
required on the producer side but not for decoder.

Zhao Zhili (3):
  avcodec/hevc: Rewrite scalability_mask_flag parse in decode_vps_ext
  avcodec/hevc/ps: Add basic HEVC_SCALABILITY_AUXILIARY support
  avcodec/hevc: Add alpha layer support
