Distinguish between two different types of "gauge" type metrics: Actual
gauges which (at least conceptually) have a single continuous value, and
metrics which are comprised of discretely sampled values, possibly from
multiple sources.
Real gauges with continuous values don't have mean/average/deviation
values directly associated with them, as calculating these requires
sampling or some other analysis.
Sampled metrics on the other hand do have these associated values.
Clarify which function does what and where each value comes from.

Rename structs and variables to make it clear that these min/max values
are min/max per-sec rate values.
Carry mins and maxes separately from averages. This changes the meaning
of $command_ps_avg away from an "average of averages" to an actual
average, which is more accurate.
Calculate this average based on per-interval differences and interval
duration (stats_rate_min_max_avg_sample).
Side effect: As rtpe_latest_graphite_interval_start is now set in
print_graphite_data instead of in graphite_loop_run, the test now
reports a different "interval calls duration".

Perform accumulation of stats only once (i.e. increasing an actual
counter) and report stats based on differences to previous values,
instead of carrying multiple stats counters for each metric and
resetting each counter to zero whenever stats are reported.
`rtpe_stats` is the global master accumulator.
`_intv` variables are intermediate and local storage for values sampled
from `rtpe_stats` at regular intervals.
`_rate` and `_diff` variables hold stats calculated from `rtpe_stats`
and the respective `_intv` variable whenever the sampling and reporting
occurs.
`stats_counters_calc_diff` is used to calculate stats as differences
between `rtpe_stats` and the last sampled `_intv`
`stats_counters_calc_rate` does the same but calculates a per-second
rate, based on a microsecond duration.
Eliminate now-useless struct global_stats_ax

Use dedicated functions and different code paths for the different use
cases, instead of just a single function which does if/else all the
time.

In order to rewrite certain session-level SDP lines, we need to
reference a packet_stream which contains the correct information. But we
cannot simply rely on the first media section having a usable packet
stream, as the first media section could have been rejected. Iterate
media sections until we find a usable one.

This fixes the payload counts not being tracked correctly when payload
types repeat after the tracker rolls over.

The SRTP decryption context is associated with the local socket. Use the
socket that a packet was actually received on for the decryption context
instead of using the one that it was expected to be received on.

(cherry picked from commit 8c3452e50b7aa4f5b7122dbd7221e34143467885)
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.

Our own Janus WS client would create a single WS session and then create
all rooms under this one session and run all publishes and subscribers
under the same session. This is not a restiction imposed by Janus
though, which allows participation in one room by multiple sessions.
Remove this restriction to more closely mirror Janus behaviour.

Apparently Janus allows a single handle to be both controller and
publisher, and possibly also both publisher and subscriber. Remove the
limitation that forces one handle to only take one role.
