avutil/hcontext_cuda: Remove unnecessary stream synchronisation

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.

avcodec/cuviddec: Remove unnecessary stream synchronisation

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.

avfilter/vf_yadif_cuda: Remove unnecessary stream synchronisation

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.

lavc/qsvenc_h264: remove the privite option trellis

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.

avfilter/vf_lensfun: add scale parameter

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.

avformat/rtsp: Add https tunneling support

Add https based tunneling for RTSP/RTP. Tested on Axis and Bosch cameras.
Https is widely used for security consideration.

avcodec/av1_parser: don't abort parsing the first frame if extradata parsing fails

The first frame contains the sequence header, which is needed to parse every
following frame.

This fixes parsing streams with broken extradata but correct packet data.

  arm: Implement a NEON version of 422 h264_h_loop_filter_chroma

Merged-by: James Almer <jamrial@gmail.com>

lavd/v4l2-common: Add an entry for Z16.

lavfi/colorspace_common: add ifdef check to be more compatible.

Some filters may not need to do linearize/delinearize, thus
will even not define them. Add ifdef check, so they could easily
re-use the .cl file.

lavu/opencl: replace va_ext.h with standard name

Khronos OpenCL header (https://github.com/KhronosGroup/OpenCL-Headers)
uses cl_va_api_media_sharing_intel.h. And Intel's official OpenCL driver
for Intel GPU (https://github.com/intel/compute-runtime) was compiled
against Khronos OpenCL header. So it's better to align with Khronos.

avfilter/af_astats: add support for selecting measured statistics

set_metadata with many entries is not very efficient, and with small audio

calculations (like peak) can be even further optimized.

output, so factorizing calculations and output might not worth the hassle.
