If there is a single group of SPS/PPS before an IDR frame, but no
SPS/PPS after that, we will miss the chance to reset
idr_sps_seen/idr_pps_seen. The result is missing SPS/PPS for all
IDR frames except the first one.

This is a POC for adding hevc alpha layer decoding support. I'd like to
know:
1. Is there any plan/interesting to add fullly support inside our hevc
decoder? If the answer is yes, then the patchset is less useful.
2. What does the current method break?

It can be used to decode selected independent non-base layer. One
use case is alpha layer decoding.
