Fix ticket #7297
The current setting for send-expect-100 option is either
enabled if applicable or forced enabled, no option to force
disable the header. This change is to expand the option setting
to provide more flexibility, which is useful for rstp case.

Similarly to the previous changes, we don't need to synchronise
after a memcpy to device memory. On the other hand, we need to
keep synchronising after a copy to host memory, otherwise there's
no guarantee that subsequent host reads will return valid data.
We're also doing a sync here after copying the frame to be passed
on down the pipleine. And it is also unnecessary.
I was able to demonstrate a 33% speedup removing the sync from
an example transcode pipeline.
I put this call in by habit, rather than because there was any
actual need. The filter is simply processing frames one after
the other and has no need to synchronise.
malakudi on the devtalk forums noticed a slowdown when using nvenc
with temporal/spatial aq and that the slowdown went away if the
sync call was removed. I also verified that in the basic encoding
case there's an observable speedup.
I also verified that we aren't doing unnecessary sync calls in any
other filter.
The following are the newly added options:
arnr_max_frames, arnr_strength, aq_mode, denoise_noise_level, denoise_block_size,
rc_undershoot_pct, rc_overshoot_pct, minsection_pct, maxsection_pct, frame_parallel,
enable_cdef, enable_global_motion, and intrabc.
Also added macros for compiling for aom 1.0.0 and fixed the default values.

cbs trace qsv vps header failed due to some reasons:
1. vps_temporal_id_nesting_flag is not set but spec required it must to
be 1 when vps_max_sub_layers_minus1 is equal to 0.
2. vps_num_hrd_parameters is not set and written.
3. other issues in ff_hevc_encode_nal_vps() (fixed in pervious commit_id: 520226b683).
Reproduce: ffmpeg -hwaccel qsv -v verbose -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal.mp4 -vframes 1

Right now, the code check for no filter description, but if we use a
filter_complex, the code will use the AVFrame.duration which could be
wrong in case of using fps filter.
How to reproduce the problem:
ffmpeg -f lavfi -i testsrc=duration=1 -vf fps=fps=50 -vsync 1 -f null -
output 50 frames
ffmpeg -f lavfi -i testsrc=duration=1 -filter_complex fps=fps=50 -vsync 1 -f null -
output 51 frames
With this commit, the same command will always output 50 frames.

There are many problems of current qsv trellis option:
1. Duplicated with AVCodecContext definition
2. MFX_TRELLIS_XXX is introduced by MSDK API 1.17
Currently Without MSDK API checking thus may cause compilation issue.
3. user is inclined to enable trellis when set "-trellis 1", but
actually it is to disable since MFX_TRELLIS_OFF is equal to 1.
4. It is too complex for user to enable trellis for every frame(I/P/B).
Just simply remove the private option, and switch to the AVCodecContext
definition. Compatibility should not a big problem (except can't exact map)
since the option name is same as AVCodecContext.

The lensfun filter wraps the lensfun library which performs
transformations on videos to correct for lens distortion. Often this
results in areas in the input being mapped to areas that fall outside
the boundaries of the output. The library has a parameter called scale
which is a scale factor applied to the output video. By decreasing it it
is possible to regain the areas of the video which would otherwise have
been lost. There is a special value of 0 which indicates that the
library should automatically determine a scale factor that results in
the output frame being filled (i.e. little or no black/unmapped areas).
This patch adds a corresponding scale option to the lensfun filter which
is passed through to the library. The existing behaviour of using the
automatic value of 0 is retained as the default behaviour, while other
values will be passed through to the library.
