Keep a running lifetime total of all "gauge" type metrics. Also track
the square of the sums of all "gauge" type metrics in order to determine
the standard deviation.

Starting with release 5.1, ffmpeg obsoletes the `channels` and
`channel_layout` fields, replacing them with a unified `ch_layout`
struct of type AVChannelLayout. Add wrapper defines into the
compile-time build-test headers fix_frame_channel_layout*.h to
accommodate both new and old versions.

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.

To prevent a race condition that might miss updates about call info, set
up the Redis keyspace notifications first and then run loop to restore
calls from the existing data.

Allow override the bitrate if one is already set, as opus_init()
initially sets a default bitrate, which is then overridden by codec-set.

The PT tracker doesn't distinguish between audio/media types and
supplemental types, so in order not to break DTMF handling we must take
all combinations of primary (audio/media) types and supplemental types
as both input types and handler types into account.

To safeguard against non-refcounted objects being left over in a log
info piece (e.g. a string on the stack), add this new function to pop
pieces from the stack until the desired one is removed. This is needed
in case of a unpaired log_info_* without a matching log_info_pop.

The codec answer routine resets the codec storage and so also resets the
clock rate tracker for "touched" codecs. This leads to all codecs seen
as "not touched" in the answer routine, which in turn leads to
supplemental codecs present in the answer SDP that should not be there.
Use the "for transcoding" flag for previously present codecs to retain
the "touched" status across the codec answer routine.

When doing the initial answer, the packet_stream endpoint port isn't

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.

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.
