Delay allocating the structures until really needed.
First do checks agains the opened connection, and if an issue is
detected simply close the fd.
Next, fetch or allocate the related peer.
Finally, create the link from the fd.
This makes it easier to add early extra checks later when peers will
contain info on link_mode (client|server|disabled) later on.

* link -> srv_link to avoid confusing with cbsp/sbcap links
* clients -> links, since it holds links, which in the future will be
both TCP/SCTP clients and servers.

Rename osmo_*_cbc -> cbc_*_mgr:
Now they only hold TCP/SCTP server related conns, but will also hold
TCP/SCTP client conns in the near future.
Rename osmo_cbc_*_client -> cbc_*_link:
The term "client" is confusing, since it doesn't exist in CBSP/SBcAP,
and will later support connecting to server at TCP/SCTP level.
Let's use "link" instead, similar to what's used in osmo-bsc which
already supports both TCP client and server modes.

Let's create missing header files and move stuff around to have a clear
view of who implements what.

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.
