In the past, we used a FIFO structure (first in, first out) - which
obviously cannot deal with packet re-ordering on the IP side.
This patch introduces a new "RIFO" as a replacement for the FIFO.
The RIFO is able to reconstruct E1 frame ordering by using the
reduced frame number from the TDMoIP messages, at least as long
as the related frame number range is within the current RIFO depth.

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.
