osmo-cbc already supported the transmission of UCS2 characters for quite
some time. However, the cbc-apitool didn't expose this capability so
far.

ASN1C encoding/decoding can get really verbose. Furthermore, it should
only be enabled under really specific conditions, so it makes sense to
have it under its own category.

This patch adds support to set up a CBSP link so that osmo-cbc connects
as a TCP client to the BSC, which runs as a TCP server.
Similary, support to set up a SBc-AP link so that osmo-cbc connects
as a SCTP client to the MME, which runs as SCTP server.
A new "mode (client|server|disabled)" VTY command is added to use one
mother or the other, and also to disable the link and hence the peer
until it is set again. This is useful if the peer is under manintenance
for instance.
client sockets are created automatically when the "peer" vty node is
exited if the link is not yet created, hence creating it at startup or
if moved back from "disabled" mode. If client socket dies, it will
keep attempting reconnect every 5 seconds.

This way it's clear and we have in one place all the related code that
neds to be run at a given time.t

This way we lock the type (proto) of each peer at creation time.
Otherwise, having the possibility of changing the protocol of the peer
makes all the code too complex and there's no good way to prevent the
protocol from being changed at any time creating unexpected issues.
If the user wants to change the protocol, she can do so by removing the
peer and re-adding it through the VTY with the desired protocol.

This patch makes use of the newly introduced sbcap library, and
introduces new code (and extends existing one) to handle all the aspects
of MME peers talking SBc-AP and its underlaying SCTP connection.
This commit doesn't aim to implement all the SBc-AP features, but to
implement a minimal subset of features already available for CBSP in
osmo-cbc, in order to have similar support level for both 2G and 4G
networks.

This example is not any better than just using '-c /dev/null'.
Add some default parameters taken from 'show running-config'.
