Export TUN device statistics from the worker process.

Browse Source 
When a worker process terminates in authenticated state, then
export statistics from the tun device (currently bytes_in and
bytes_out). These statistics are sent to main process using an
informational message just prior to process exit. The statistics
are also exported to the disconnect script using the STATS_BYTES_IN
and STATS_BYTES_OUT environment variables.

requires the reload of all certificates/parameters on the worker
process, and imposes a quite high penalty (see the 'exec' branch).
* On worker process exit, send the main process the packet/bytes statistics
of the tun device. That would allow the main process to report them
to the disconnect script. That will most probably require ocserv to
be linked with libnl3, and more system calls to be allowed by seccomp.
* Think for ways for ocserv to co-exist on the same system with
an HTTPS server (while sharing the same port).
