b7e1821284 hevc: move SliceHeader and LongTermRPS back to hevcdec.h 
They are no longer necessary there and have nothing to do with parameter
sets, so do not belong in hevc_ps.h.

This effectively reverts 4aaace8b25.

939a4db227 lavc/hevc: Add poc_msb_present filed in LongTermRPS 
delta_poc_msb_present_flag is needed in find_ref_idx() to
indicate whether MSB of POC should be taken into account.

Details in 8.3.2.

0d83fcc07b lavc/hevc_ps: parse constraint flags for HEVC REXT 
Parse all the constraint flags according to ITU-T Rec. H.265 (02/2018).

They have to be passed to hw decoders to determine the exact profile for Range
Extension HEVC.

f4ea930a11 avcodec/hevc_ps: Expose all SPS and PPS range extension flags 
We need all the flags to be exposed to be able to pass them on to
HW decoders. I did not attempt to nuance any of the warnings about
flags being unsupported as there's no way, at the point we extract
flags, to say whether an HW decoder is being used.

b1374e925c hevc: Improve stream constraint values in common header 
Add comments to describe the sources of the constraint values expressed here,
and add some more related values which will be used in following patches.

Fix the incorrect values for SPS and PPS count (they are not the same as those
used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere.

(cherry picked from commit b88da98b34)

f6e2f8a9ff hevcdec: move parameter set parsing into a separate header 
This code is independent from the decoder, so it makes more sense for it
to to have its own header.
