1389b4c18d idct8x8: Fix undefined negative shifts 
The original code left-shifts negative values, which is undefined
in the C99 specification (the one used during normal Libav compilation).
This change multiplies by (1 << shift), which is functionally equivalent,
but has defined behavior.

With this change, fate-idct8x8 compiled with --fsanitize=undefined works.

8958c5c64d 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.

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.
