If a read fails, the current code will free the data but leave the size
non-zero. Make sure the size is zeroed in such a case.

A negative chunk size is illegal and would end up used as
length for memcpy, where it would lead to memory accesses
out of bounds.

This moves work from the configure to the Make stage where it can
be parallelized and ensures that pkgconfig files are updated when
library versions change.

When the input string is too large, so the second condition in if ()
fails, the code will erroneously execute the else branch, indexing the
mac_to_unicode table with a negative index.

When receiving fragmented packets, the first packet declares the size,
and the later ones normally are small follow-on packets that don't repeat
the size and the other header fields. But technically, the later fragments
also can have a full header, declaring a different size than the previous
packet.
If the follow-on packet declares a larger size than the initial one, we
could end up writing outside of the allocation.
This fixes out of bounds writes.

This seems to have been added by mistake in 11de006b, by not
noticing the negation for the existing condition. This block does
not contain any code that accesses the codec field in AVStream.
This function is meant to serve as a complement to compute_pkt_fields2,
which is guarded by FF_API_COMPUTE_PKT_FIELDS2 && FF_API_LAVF_AVCTX.

Supporting the system was a nice joke for the 9 release, but it has
run its course. Nowadays Plan 9 receives no testing and has no
practical usefulness.
The rtmpdh code can use crypto libraries which may require
a process global init. (gcrypt is one of the libraries
where the rtmpdh test code can fail if global init hasn't been
done, depending on gcrypt version.)

Functionally similar to av_packet_add_side_data(). Allows the use of an
already allocated buffer as stream side data.

avctx->pkt_timebase is not correct, leading to A/V desync.

complete STREAMINFO metadata as part of the last packet, so write that
to CodecPrivate instead of the incomplete one available in extradata

aac_adtstoasc makes the aac extradata available only after the first packet
is filtered, and as packet side data.
Assume extradata will be available as part of the first packet if
avpriv_mpeg4audio_get_config() fails the first time due to missing extradata
and reserve space for the OutputSampleRate element in the Tracks master.

This matrix needs to be applied after all others have (currently only
display matrix from trak), but cannot be handled in movie box, since
streams are not allocated yet. So store it in main context, and apply
it when appropriate, that is after parsing the tkhd one.
Fate tests are updated accordingly.

The use of TLSv1_*_method() disallows newer protocol versions; instead
use SSLv23_*_method() and then explicitly disable the deprecated
protocol versions which should not be supported.
