Audio rework, new jitter buffer
...
Jitter buffer is now based on packets, not on samples. The frames are
dejittered in received form. After reading from jitter buffer, they are
decoded in correct order. If a frame is missing, it is concealed by
repeating audio.

Fix DTMF detection from called end
...
Now DTMF detection called end. Imagine Paypal calls you and asks you to
enter digits. The routing script can then enable dtmf detection on the
called end (after answer) and forward digits via telephone events.

Fix for SIGABRT if redirecting stdout or running osmo-cc-router within systemd
...
If using osmo-cc-router with a configured call routing script and redirecting stdout to a file
(e.g. osmo-cc-router --config cc-router.cfg >logfile), router process aborts upon starting a call with message
"communication with child failed!" because unexpected characters are received by the parent process.
Running the router with systemd causes the same problem. Avoiding any standard file descriptors
after the dup2() within the child fixes it.

Provide CC metering information to endpoints
...
A new routing command 'metering' has been added. It has two parameters to specify metering information:
- connect_units (units charged upon answer, normally '1'; set to '0' to mark the call as free of charge; set to higher value to add a call-setup charge)
- period_decisecs (time period of one unit in 1/10 seconds; set to '0' for a call-setup charge only)
Metering details are encoded within IE_METERING and attached to the next outgoing CC-PROC-REQ/CC-ALERT-REQ/CC-SETUP-RSP message for the call originator.
