2544c7ea67 avfilter/vf_scale_cuda: Switch to using ffnvcodec
This change switches the vf_scale_cuda filter from using the
full cuda sdk to using the ffnvcodec headers and loader.

Most of the change is a direct mapping, but I also switched from
using texture references to using texture objects. This is supposed
to be the preferred way of using textures, and the texture object API
is the one I added to ffnvcodec.

5f47bfd50a configure: Add an explicit check and option for nvcc
The use of nvcc to compile cuda kernels is distinct from the use of
cuda sdk libraries and linking against those libraries. We have
previously not bothered to distinguish these two cases because all
the filters that used cuda kernels also used the sdk. In the following
changes, I'm going to remove the sdk dependency from those filters,
but we need a way to ensure that nvcc is present and functioning, and
also a way to explicitly disable its use so that the filters are not
built.

97f47fd601 mov: Fix start_time for streams with empty edits in the middle
Empty edits can occur at any position within the edit list except for at
the end. Empty edits in the middle should not impact the reported stream
start_time or the video PTS adjustment, so only include empty edits at
the start of the list in empty_edits_sum_duration.

This avoids making invalid HTTP Range requests for a byte range past the
known end of the file during a seek. Those requests generally return a HTTP
response of 416 Range Not Satisfiable, which causes an error response.

9d5ca71ec2 vaapi_encode: Do not zero access unit structures
Following b8c45bbcbc they contain allocated
unit arrays which will get leaked.  These operations were inconsistently
applied and never actually needed (the old uninit left them in the correct
state), so just drop them entirely.

b8c45bbcbc libavcodec/cbs: Stop needlessly reallocating the units array
Currently, a fragment's unit array is constantly reallocated during
splitting of a packet. This commit changes this: One can keep the units
array by distinguishing between the number of allocated and the number
of valid units in the units array.

The more units a packet is split into, the bigger the benefit.
So MPEG-2 benefits the most; for a video coming from an NTSC-DVD
(usually 32 units per frame) the average cost of cbs_insert_unit (for a
single unit) went down from 6717 decicycles to 450 decicycles (based
upon 10 runs with 4194304 runs each); if each packet consists of only
one unit, it went down from 2425 to 448; for a H.264 video where most
packets contain nine units, it went from 4431 to 450.

The function typedefs we were using are only present when using the

8cf757ee8d ffmpeg_filter: initialize sub2video.end_pts together with last_pts
This way re-initializations properly update end_pts, enabling
sub2video_heartbeat to call sub2video_update as expected to re-init
the sub2video AVFrame's contents and to feed a frame into the filter
chain.

This then fixes memory usage ballooning due to framesync waiting
for secondary input in case of no actual subtitle samples being present
for a while in source after a re-init occurs.
