1329c08ad6 hevc: Validate the number of long term reference pictures 
This would overflow if the stream contained a value greater than the
maximum allowed by the standard (32).

b88da98b34 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.

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.

c359d624d3 hevcdec: move decoder-independent declarations into a separate header 
This way they can be reused by other code without including the whole
decoder-specific hevcdec.h
Also, add the HEVC_ prefix to them, since similarly named values exist
for H.264 as well and are sometimes used in the same code.

4abe3b049d hevc: rename hevc.[ch] to hevcdec.[ch] 
This is more consistent with the rest of libav and frees up the hevc.h
name for decoder-independent shared declarations.

1ecb63cd1c hevc: set profile based on the profile compatibility flags if needed 
This fixes retrieving a valid profile for many of the FATE conformance samples,
allowing them to be properly decoded by the HWAccel after adding a profile check.

8c399bd5ce dxva2_hevc: properly signal the num_delta_pocs from the SPS RPS 
ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS,
and not the final computed value from the slice header RPS, as this calculation
is done internally by the driver again.

b9f76d19d8 hevc_ps: make sure failing to decode an SPS always returns an error 
Some of the goto err clauses do not set the error code. It seems better
to fall back on INVALIDDATA instead of adding it everywhere explicitly.
