22c4f33991 avfilter/avfiltergraph: Simplify adding filter to graph
By reallocating the array of pointers to the AVFilterContexts
before allocating the new AVFilterContext one can avoid freeing
the new AVFilterContext in case the array could not be reallocated.

Also switch to av_realloc_array() while just at it.

09408539f4 checkasm/hevc_pel: Fix stack buffer overreads
This patch increases several stack buffers in order to fix
stack-buffer-overflows (e.g. in put_hevc_qpel_uni_hv_9 in
line 814 of hevcdsp_template.c) detected with ASAN in the hevc_pel
checkasm test.
The buffers are increased by the minimal amount necessary
in order not to mask potential future bugs.

ff80090374 avutil/utils: Remove racy check from avutil_version()
avutil_version() currently performs several checks before
just returning the version. There is a static int that aims
to ensure that these tests are run only once. The reason is that
there used to be a slightly expensive check, but it has been removed
in 92e3a6fdac. Today running only
once is unnecessary and can be counterproductive: GCC 10 optimizes
all the actual checks away, but the checks_done variable and the code
setting it has been kept. Given that this check is inherently racy
(it uses non-atomic variables), it is best to just remove it.

c20577806f avformat/aacdec: enable probesize-sized resyncs mid-stream
Before adts_aac_resync would always bail out after probesize amount

Now just query the current position when entering resync, and at most
advance probesize amount of data from that start position.

3f11eac757 avcodec/encode: Set AV_PKT_FLAG_KEY based upon AV_CODEC_PROP_INTRA_ONLY
Currently, the AV_PKT_FLAG_KEY is automatically set for audio encoders;
yet this is wrong, as both MLP and TrueHD have non-keyframes. So set it
based upon AV_CODEC_PROP_INTRA_ONLY (from the corresponding
AVCodecDescriptor) instead. This also sets it for some video codecs,
which is intended.

TrueHD/MLP is one of the audio formats with keyframes. Currently,
the generic encoding code just sets the keyframe flag for all
returned packets, yet this is wrong for these encoders and will
be changed in a future commit. So set the flag here for those
packets that ought to have it.

abort encoding with "DTS is invalid." when no B-frames are
generated.
