7070955d43 libaomenc: Add support for tiles 
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.

fb7925ba2f fate: add api-h264-slice test

0a055f463a lavc/h264dec: don't error out when receiving multiple IDR slices 
This error isn't particularly helpful as checking for mixed IDR/non-IDR
NALUs would need to be done at a higher level to actually be accurate.
Removing the error allows an API user to send individual slice NALUs
(i.e. incomplete frames) so they can take advantage of slice
threading. The ticket which this error was added for (#4408) no
longer segfaults after removing this error (as the bug was likely
fixed more properly elsewhere).

b02490a497 avcodec/libx264: remove FF_CODEC_CAP_INIT_THREADSAFE flag 
Libx264 uses strtok which is not thread safe. Strtok is used in
x264_param_default_preset in param_apply_tune in x264/common/base.c.
Therefore the flag must be removed.

x264 fixed the issue, once the fix is pushed to stable, an #if can be added
to re-enable the flag based on X264_BUILD number.

Fixes ticket #7446.

87588caf8c Revert "avcodec/decode: copy the output parameters from the last bsf in the chain back to the AVCodecContext" 
This reverts commit f631c328e6.

The avcodec_parameters_to_context() call was freeing and reallocating
AVCodecContext->extradata, essentially taking ownership of it, which according
to the doxy is user owned. This is an API break and has produced crashes in
some library users like Firefox[1].

Revert until a better solution is found to internally propagate the filtered
extradata back into the decoder context, or a decision is made to change the
API.
