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.

Don't increase the index pointer before using it. This fixes slots 1 and
2 being filled before slot 0, which ends up filling slots 0 and 2 first
(due to swapping with slot 0), leaving slot 1 empty.

When ports are closed early (while the call is still running), we must
first update a slave rtpengine with this new information (that these
ports are now closed) before actually releasing the ports ourselves. Not
doing so leads to a race condition where the master instance re-uses a
port that was just closed before the slave instance knows about the port
being closed.
We implement this using a thread-local list to keep track of ports that
were released while processing a control message, and process this list
to actually close the ports only after Redis has been updated.
Additional calls to the function to close the ports are placed in
strategic locations to make sure this is triggered in every code path.

Despite this code being called from userspace, we must disable
interrupts while having ssrc_stats_lock acquired, as the same lock is
acquired elsewhere from within an interrupt context.

This prevents empty mixed output files from being created when mixed

Provide a standard output format if no other outputs are configured, so

DTX and delay buffers and their timers are shut down during the codec
negotiation phase, which also happens for the offer side while
processing an answer. If the codec negotiation routine determines that
the existing codec handlers can be kept intact, we must restart the DTX
and delay buffers that have previously been shut down.
Buffer objects are never freed during a shutdown, therefore we simply
need to restore the contained references to indicate that these buffers
are active again.

Instead of always generating a new ICE foundation string for every
learned peer-reflexive candidate, try to use the same foundation string
for candidates that belong together. We use the priority number plus the
component ID for this to see if we've learned a candidate with a fitting
priority number before. If we have then re-use the same ICE foundation
string. This allows ICE to complete with only learned prflx candidates
and without (or before) re-invite to communicate the correct ICE
foundations.

`flags` being NULL is not really a use case we have right now, but it

Initialising the other members of this struct is not really necessary as
they're not used in the hash lookup. But let's do it anyway.

Keep track of how many streams have been added to the DB for each call.
Then at the end of the call, if there are no corresponding streams in
the DB, delete the entry for the call instead of marking it as complete.
This eliminates DB entries for calls that were cancelled or failed.

Since we're creating a dummy sfd to hold the SRTCP context when we don't
have an actual RTCP port, we must make sure to remember and re-use this
dummy sfd during a re-invite. Otherwise we end up creating a duplicate
dummy sfd, which is detected as a different sfd and thus triggers an ICE
restart.

Setting the mux flag when rtcp-mux is given is fine, but we must still
provide an RTCP endpoint in case rtcp-mux ends up not being used, either
through an implicit RTCP endpoint or through a=rtcp.
