5d324dae11 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.

d82e1adc20 hevc: move splitting the packet into NALUs into a separate function 
This function is independent of the decoding context, so we'll be able

ae05b48655 hevc: eliminate the second call to hls_nal_unit() 
Also, make hls_nal_unit() work only on the provided NAL unit, without
requiring a whole decoding context.

This will allow splitting this code for reuse by the parser.

1b19d0c632 avcodec/hevc: Track long and short term RPS size for VDPAU 
Today, we track the short term RPS size for DXVA, but only if the
SliceHeader RPS is being used. Otherwise it's left uninitialized.

NVIDIA's VDPAU implementation requires that the size be accurately
tracked even if an SPS RPS is being used. In this case, it's really
counting the size of the RPS idx information, but you end up with
mangled output if the value is not accurate.

VDPAU also needs the size of the long term RPS.

da81cc38e8 avcodec/hevc: reduce memory for SAO 
cherry picked from commit 5d9f79edef2c11b915bdac3a025b59a32082f409

SAO edge filter uses pre-SAO pixel data on the left and top of the ctb, so
this data must be kept available. This was done previously by having 2
copies of the frame, one before and one after SAO.

This commit reduces the storage to just that, instead of the previous whole
frame.
