1b45405d44 tests/fate-run: add testing with a random number of threads 
Useful for discovering bugs that depend on a specific thread count.

Use like THREADS=randomX for a random thread count from 1 to X, with
X=16 when not specified. Note that the thread count is different for
every test.

d694c25b44 avutil/random_seed: add av_random_bytes() 
Uses the existing code for av_get_random_seed() to return a buffer with
cryptographically secure random data, or an error if none could be generated.

ac4247270c avdevice/decklink_enc: add support for SMPTE 2038 VANC packet output 
Support decoding and embedding VANC packets delivered via SMPTE 2038
into the SDI output.  We leverage an intermediate queue because
data packets are announced separately from video but we need to embed
the data into the video frame when it is output.

Note that this patch has some additional abstraction for data
streams in general as opposed to just SMPTE 2038 packets.  This is
because subsequent patches will introduce support for other
data codecs.

Thanks to Marton Balint for review/feedback.

73a2252f1d avfilter/vf_bwdif_cuda: CUDA accelerated bwdif deinterlacer 
I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
