avplay: remove a warning

Set the data field in the flush_pkt to the pointer to the actual packet.
The field needs to contain a valid unique pointer, no read nor writes
are ever made to it.

h264_refs: Do not print check_opcodes() return value

The return value provides no useful information and removing the printing
avoids the following warning:
libavcodec/h264_refs.c:788:15: warning: 'i' may be used uninitialized in this function [-Wuninitialized]
aac: check the maximum number of channels

Broken bitstreams could report a larger than specified number of
channels and cause outbound writes.

doc/filters: apply various general fixes to vidstabdetect docs

Adopt generally used conventions, extend and clarify explanations.
lavfi/transpose: apply grammar consistency fixes to transpose dir option
lavfi/mp: remove mp=tinterlace wrapper

From various tests, there is no evidence that the filter is faster than
the native tinterlace, and it has several more limitations and a few
bugs.
