As soon as an OCTOI connection gets into ACTIVE state, send a
ECHO_REQ every 10s and compute the RTT at the time of receiving
the response.
Contrary to the initial idea, the stat item contains the RTT (round trip
time) measured in micro-seconds. Changing this is not a problem as so
far the RTT was always reported as '0', and 0ms == 0us.

This introduces initial support for operation as OCTOI (Osmocom
Community TDMoIP) server and client operation.
Various features are still absent (user authentication, support for
re-ordered packets), but this version is already able to provide
services to clients with dynamic IP addresses as well as servers.
The bulk of the OCTOI / E1oIP code is implemented as a shared library,
to facilitate the development of other servers and clients in the
future, and also to minimize the impact on the existing osmo-e1d code
base.
