  hevc_filter: move some conditions out of loops

Conflicts:
	libavcodec/hevc_filter.c

This is possibly less readable than the variant used before.
Thus please take a look and if people agree its worse, dont
hesitate to revert.

7acdd3a127 hevc_filter: avoid excessive calls to ff_hevc_get_ref_list() 
1) each of the loops run within a single CTB, so the relevant reference
list is constant
2) when that CTB is, or lies on the same slice as, the current one, we
can use a simple access instead of a relatively expensive call to
ff_hevc_get_ref_list()

ad1ee5fa75 avcodec: Undeprecate reordered_opaque 
It allows attaching other external, opaque data to the frame and passing it
through the reordering process, for cases when the caller wants other data
than just the plain packet pts.  There is no way to cleanly achieve this
without the field.

7b588bb691 svq1: do not modify the input packet 
The input data must remain constant, make a copy instead. This is in
theory a performance hit, but since I failed to find any samples
using this feature, this should not matter in practice.

Also, check the size of the header, avoiding invalid reads on truncated
data.
