45b18fbb9a rsd: limit number of channels
Negative values don't make sense and too large values can cause
overflows. For AV_CODEC_ID_ADPCM_THP this leads to a too small extradata
buffer being allocated, causing out-of-bounds writes.

3047b0a4a3 icodec: correctly check avio_read return value
It can read less than the requested amount, in which case buf contains
uninitialized data, causing problems like segmentation faults later on.

Also make sure that image->size is positive, so that it can't match a
negative error code.

0009cf348a avformat: prevent triggering request_probe assert in ff_read_packet
If probe_codec is called with pkt == NULL, it sets probe_packets to 0
and request_probe to -1.
However, request_probe can change when calling s->iformat->read_packet
and thus a probe_packets value of 0 doesn't guarantee a request_probe
value of -1.
In that case calling probe_codec again is necessary to prevent
triggering the assert.

f3c1a76ffd avformat/allformats: Making av_register_all() thread-safe.
When multiple threads tries to call av_register_all(), the first thread sets
initialized to 1 and do the register process. At the same time, other thread might
also call av_register_all(), which returns immediately because initialized is set to 1
(even when it has not completed registering codecs). We can avoid this problem
if we set initialised to 1 while exiting from function.

Leaking this private structure opens up the possibility that it may
be re-used when parsing later packets in the stream. This is
problematic if the later packets are not the same codec type (e.g.
private allocated during Vorbis parsing, but later packets are Opus
and the private is assumed to be the oggopus_private type in
opus_header()).
