cc5e4bb484 hevc: make avcodec_decode_video2() fail if get_format() fails 
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().

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.
