This fixes a race condition: Peer sends updated SDP with new address,
but an older RTP packet from the old address is received afterwards.
Thsi triggers learning of this old address is the "correct" endpoint.
Afterwards the peer stops sending RTP until a packet to the new endpoint
is received there, which never happens because the new endpoint has been
discarded in favour of the "learned" old one.

Perform reverse SSRC mapping even if output media is not known, and use
the appropriate media side when looking up SSRCs for received RTCP
timestamps.

This solves problems when the same SSRC is looped through the same call
multiple times in different mono/dialogues, with different parameters.

Transcoding should not be decided based on the name of the codec alone,
but primarily on the payload type. First the PT needs to be compared,
then the codec type must be confirmed.

GLib 2.68 deprecates g_memdup() in favour of g_memdup2() as the former
was using a guint second argument which could lead to integer overflows
(gsize should be used instead).

This makes sure all objects are cleaned up during shutdown even if the
respective timer hasn't run yet.

Some codec handlers hold references to objects held within the
statistics hash table, therefore we must free the statistics after all
codec handlers have been released.

Recent ffmpeg versions have removed AVPacket from the public ABI,
therefore deprecating av_init_packet on statically allocated objects.
The replacement is av_packet_alloc()/av_packet_free().

Expanding the initialiser of the contained array eliminates a stray

We should eventually try to reduce the amount of -Wno-* options, but for

These functions can return negative values to signal errors, therefore
use ssize_t as appropriate type.

get_ssrc_ctx() returns a new reference to the SSRC object, therefore we
must release the referece when we're done with it.

Convert ssrc_ctx_put() and ssrc_ctx_hold() to macros to aide in
debugging reference leaks. Having them as inline functions hides the
actual location of the refcount changes.
Obsolete ssrc_ctx_get() as returning values from macros is awkward and
it was only used in two locations.
Also fix a function invocation mishap: obj_get_o() should be used
instead of __obj_get() as the latter is an internal macro.

This makes the type in line with string(3) functions and eliminates some

The SSRC mapping strategy can change if a re-invite disengages
transcoding, therefore we always need to update the output SSRC mapping
even if the SSRC entry has already existed, to avoid stray SSRC changes.

Make sure the pointers we return from our continuous memory buffer is
always 64-bit aligned as it's used not only for strings, but also for
structs/objects, and such unaligned memory access is undefined on some
archs and flagged as such by ASAN.

Avoid accessing memory via pointers that may not be aligned, which is
undefined behaviour on some archs. Use memcpy for this purpose instead.

Check if the uint64_t pointer is aligned before using it. If unaligned,
go byte by byte. Unaligned pointer access is undefined on some archs and

Since dh_auto_test doesn't execute the test suites through make
directly, but instead runs `make -s -n` and then executes the output,
the integrated build tests fail since the sub-make doesn't return an
error as it should when attempting to build with the wrong .h
alternative, resulting in always the first .h alternative being used.
Fix this by using a wrapper script instead.
Also adjust some other related minor build details.

If we receive an SDP with a DTLS fingerprint, by default we adopt the
hash function used for that fingerprint in subsequent communication with
that peer. However, if the SDP is an answer, and we previously used a
different hash function in the offer towards that peer, then a later
re-invite offer would be sent with a different fingerprint, causing an
unexpected DTLS restart. Instead, make sure we don't change fingerprints
if one was already sent.
