cbs_h264: Add hack for pic_timing with no active SPS
Partially fixes#6896 - the sample stream from that ticket now works, but
more obscure cases can still fail.

This is harmless and should not be a warning - unknown units are passed
through to the write functions unchanged, and no other code will interact
with them.
This removes the arbitrary limit on the allowed number of slices and
parameter buffers.

This refactor splits up the main mediacodec decode loop into two
send/receive helpers, which are then used to rewrite the receive_frame
callback and take full advantage of the new decoding api. Since we
can now request packets on demand with ff_decode_get_packet(), the
fifo buffer is no longer necessary and has been removed.
This change was motivated by behavior observed on certain Android TV
devices, featuring hardware mpeg2/h264 decoders which also deinterlace
content (to produce multiple frames per field). Previously, this code
caused buffering issues because queueInputBuffer() was always invoked
before each dequeueOutputBuffer(), even though twice as many output
buffers were being generated.
With this patch, the decoder will always attempt to drain new frames
first before sending more data into the underlying codec.

This effectively copies the side data elements from src instead of
potentially merging them with those already existing in dst.
This by extension also removes the only dependency on existing values
in the dst packet.

When ff_h264_decode_mb_cavlc() failed due to wrong sl->qscale values,
e.g. dquant out of range, set the qscale to be a valid value before
returning -1 and exiting the function. The qscale value can be used
later e.g. in loop filter.

In a recent commit the default was changed from 0 (component) to 5
(unspecified), however some standards require using 0. With this option, the
user will be able to do so.

This number is definitely required when frame threading is enabled, so
add it here rather than forcing all users to handle it themselves.
DXVA2 contained this addition in specific code as well (therefore being
added twice in the internal case) - just remove it from there.
AVCodecContext.extra_hw_frames is added to the size of hardware frame
pools created by libavcodec for APIs which require fixed-size pools.
This allows the user to keep references to a greater number of frames
after decode, which may be necessary for some use-cases.
It is also added to the initial_pool_size value returned by
avcodec_get_hw_frames_parameters() if a fixed-size pool is required.
