avfilter/vf_cuda_yadif: Avoid new syntax for vector initialisation

This requires a newer version of CUDA than we want to require.

avcodec/nvdec: Increase frame pool size to help deinterlacing

With the cuda yadif filter in use, the number of mapped decoder
frames could increase by two, as the filter holds on to additional
frames.

avfilter/vf_yadif_cuda: CUDA accelerated yadif deinterlacer

This is a cuda implementation of yadif, which gives us a way to
do deinterlacing when using the nvdec hwaccel. In that scenario
we don't have access to the nvidia deinterlacer.

libavfilter/vf_yadif: Make frame management logic and options shareable

I'm writing a cuda implementation of yadif, and while this
obviously has a very different implementation of the actual
filtering, all the frame management is unchanged. To avoid
duplicating that logic, let's make it shareable.

From the perspective of the existing filter, the only real change
is introducing a function pointer for the filter() function so it
can be specified for the specific filter.

avfilter/f_loop: switch to activate

avfilter/f_loop: make sure duration of frame is never zero

avfilter: add tpad filter

avformat/dashenc: Disable writing CODECS tag for HEVC streams

For HEVC streams, only the FourCC tag is written without profile, level etc.,
This is breaking playout support in native Safari.
Native Safari playout expects the full info in CODECS tag or None at all.
