057ea2a982 avformat: Add format_whitelist
This allows restricting demuxers to a list of needed ones for improved security
Note, some demuxers themselfs open other demuxers, these are only restricted if
AVOptions are forwarded to them. Please check that your code does that.

c37d179295 avformat: add format_probesize to allow tuning the maximum amount of bytes to identify the filetype
Currently probesize is cliped at 1mb before being used for format detection.
Alternatively this cliping could be removed but this would then tie various
things like stream analysis to the file detection.

0c1959b056 lavf: add AVFMT_FLAG_BITEXACT.
Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's
codec context.

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.

d9ae1031f5 lavf: improve handling of sparse streams when muxing
Currently ff_interleave_packet_per_dts() waits until it gets a frame for
each stream before outputting packets in interleaved order.

Sparse streams (i.e. streams with much fewer packets than the other
streams, like subtitles or audio with DTX) tend to add up latency and in
specific cases end up allocating a large amount of memory.

Emit the top packet from the packet_buffer if it has a time delta
larger than a specified threshold.

Original report of the issue and initial proposed solution by
mus.svz@gmail.com.
