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.

Personally, I need the decoder to back out if get_format() returns no
usable pixel format. This didn't work because the error code was not
propagated down the call chain. This in turn happened because the
variable declaration removed in this patch shadowed the variable, whose
value is returned at the end of the function. Consequently, failures of
decode_nal_unit() were ignored in this place.

Additionally always set the software pixel format, so it's available
even if ff_get_format() is not called later. This will be useful for
exporting stream parameters from init().
hevc seems to be the only place where the C implementation
of the av_clip function is explicitly selected, precluding
platform-specific optimizations

The buffer pointers would be otherwise overwritten, causing a
leak on e.g. PERSIST_RPARAM_A_RExt_Sony_1.

Use edge emu buffers
And enable the code unconditionally
Speed difference without USE_SAO_SMALL_BUFFER and with the new code:

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.
