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.
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.
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.
The driver bugs that caused decoded HEVC content to have an incorrect
memory layout have been fully fixed in the 410.xx driver release so
we can start exposing support.
This fixes the grammar of two HLS option descriptions and makes them less
ambiguous.

a thread count of 0 is treated the same as 1, use av_cpu_count() to get
the correct thread count when auto threads is requested.
this matches the fix in libvpxenc:

-1 will be map to error number "EPERM", and will be map to the error
message like "Error while decoding stream #0:0: Operation not permitted",
it's a strange error message when debug update_frame_pool fail,
now only return the error code from av_image_fill_pointers in case
of av_image_fill_pointers failure.

In fmp4 & sub-range mode, the output's duration always smaller than expected,
because the size of the last #EXT-X-BYTERANGE is too small.

Adds an option to specify the number of tile rows and columns, then uses
a uniform tiling if possible and otherwise a fixed tiling with equal-sized
tiles to fill the frame.
Also adds -tile-columns and -tile-rows options to make tilings with
power-of-two numbers of tiles, matching the behaviour of the libvpx/VP9
encoder.
