mtp: Allow to send SCCP/ISUP to a specific endpoint
...
For a linkset define where SCCP/ISUP should be send. This config
should probably move up to the application part when real work on
the routing is done. Right now the sccp_opc/sccp_dpc need to stay
inside the mtp_layer3.c to be able to send a TFA for the reachable
OPC and it is easier to keep both (dpc/opc) in the same file.

We are using knowledge of the SS7 application to drop outgoing

ss7: Do not send anything until both linksets in an app are up
...
We need some way to forward the failure of one link to another but
they are not normally routed so we can not send a TFP. Right now we
will simply stop responding until both links are up. This should make
the SLTM fail and trigger a re-alignment on both sides. The key here
is that the 2 * SLTM timeout needs to be higher than it takes to re-align
the link. I'm not sure this code will work.

mtp: Attempt to implement the MTP Restart properly
...
For the SSP functionatilty we will need to have the timers T18
and T20. In the period of T18 we will collect TFP/TFR/TFA for the
reachable nodes of the system. Each of this node will send us a TRA
when it is finished. Right now we assume to only have one node and
stop the T18 after the TRA of this node. Then we would need to send
the TFP/TFR we have collected. On the expiry of the T20 timer we
will need to send our TRA and notify local users.
For more complex routing we will need to have a shared routing
cache and remember which SSNs and OPCs are reachable and have inter
linkset notifications.
