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.

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.

There's no need to open ports on non-primary interfaces if ICE is not in
use as these ports will not be used or seen by anyone.
This mostly obsoletes the `save-interface-ports` config option, with the
exception of ICE advertised by the offerer. We currently have no option
to reject ICE from the offerer during the offer phase, so ports would
always be opened on that side.

We must now hold the master lock for reads from the socket as the socket
may get closed after the poller has already fired an event for it.

This is useful for functions which are used both from a timer and from
other callers. These functions would reset the logging context at their
end to free the reference held by the logging context, which would
wrongly reset the logging context when the same function was called from
a different code path. Using a stack with push/pop semantics makes it
safe to use these functions from any code path.
Additionally introduce an explicit reset function that clears the entire
stack regardless of context. This reset function is called at the end of
every work iteration in every worker thread, just in case not everything
was popped from the stack.

Not only check for the presence of a sink, but also check for a sink FD.
Treat a sink without an FD as if there is no sink.

Flag a socket with an error strike when packets are received too fast,
and refuse processing once too many strikes have occurred. This should
prevent forwarding loops from taking down the system.

Distinguish between unconfirming the learned peer address and
retriggering the kernel stream. In particular we don't want to unconfirm
the sinks every time we confirmed our own peer, as that starts an
unconfirm/reconfirm loop.

We may have multiple subscribers, some of which may be dead/unused. We
don't care if we have these since we don't forward to them anyway.

Set NO_KERNEL_SUPPORT when we don't actually kernelise the stream, and

The advertised address might be empty (trickle ICE) so use the FILLED
flag instead to see if the sink is eligible.
