When a receiving socket doesn't match the socket we were expecting, make
sure that the receiving socket is actually one of the sockets we want to
use at this point before blindly switching the socket.
This fixes a race condition after a re-invite: A new set of sockets has
been opened, but an old/delayed RTP packet still arrives on one of the
old ports. In this case we don't want to switch the local socket.

Prevent a wrongly advertised (too small) a=ptime from producing too
small buffers to hold encoded packets by flagging codecs with a fixed or
minimum frame size as such.
This is relevant to libavcodec only as the code determines the expected
frame size from the clock rate and the ptime.

1) Read dtxb->start while the lock is held (not strictly necessary as
the read should be atomic anyway)
2) Expect that dtxb->start can be larger than rtpe_now.tv
The latter can happen as `rtpe_now` in a timer thread is faked to be
exactly the time when the timer was supposed to run, and not the actual
current time, which means that a newly added packet can have a later
time stamp than the "now" the timer thread is using.

Usually supplemental RTP types (DTMF) are listed after the primary audio
codecs. In the case of the order being reversed, fix `single-codec` so
that it doesn't strip the actual audio codec that is listed after the
DTMF type.

In some cases it's possible that some packets still arrive in userspace
immediately after a stream has been pushed to the kernel, for example if
some packets are already in the queue or if there is some processing
delay (e.g. writing to Redis). Allow for a short delay before counting a
stream as userspace if it has been pushed to the kernel.

On bookworm and later, libasan reports a false positive in combination
with pthread_cleanup_push() (see [1]). Work around this by not using the
thread cleanup handler when running the asan build, and instead use a
shorter thread sleep time.

Legacy UDP/TCP control protocols don't provide information about RTP
payload types, therefore don't pretend that we know that this is RTP.
Setting the RTP flag without knowing the payload types has the undesired
side effect that unknown payload types (all of them) would not be
handled by the kernel module.

If an offer is going to a side that is already known to support
rtcp-mux, don't try to offer a fallback RTCP port. Do this by pretending
that rtcp-mux=require is set, which leads to the correct behaviour. This
is needed because the RTCP fallback port might already be closed, so
trying to include it in the offer would require opening a new set of
ports, which is undesirable.

Zero SSRC are technically invalid, but the code accepts them as valid
and therefore sets up things like crypto contexts for zero SSRCs.
Consequently it's possible to have a zero SSRC first in the list of
SSRCs and other valid SSRCs later in the list, which means we can't use
the presence of a non-zero SSRC first in the list as a flag to determine
whether SSRC tracking is in use or not. Use an explicit flag instead.

Keyspace notifications are set up before existing calls are restored
(restore_thread). Therefore the following scenario is possible:
NOTIF THREAD: receives SET, creates call
RESTORE THREAD: executes KEYS *
NOTIF THREAD: receives another SET:
NOTIF THREAD: does call_destroy(), which:
adds ports to late-release list
RESTORE THREAD: comes across call ID, does GET
RESTORE THREAD: creates new call
RESTORE THREAD: wants to allocate ports, but they're still in use
NOTIF THREAD: now does release_closed_sockets()
Use a multi-A multi-B lock to protect the two code sections from each
other and make sure that notification threads have always released all
ports before a restore thread attempts to allocate any.
