osmo-gbproxy already provides a ctrl interface, we should be able to
change ctrl-related configuration.

bssgp_tx_status() is not aware of the MTU and cannot truncate the PDU if
needed. Use the newer bssgp2_enc_status() which supports truncating the
PDU.

In some logging statements the function bssgp_rim_ri_name() is used
twice. This is wrong since _name() functions use an internal buffer,
which can not be used twice in the same logging statement, so for the
affected log statements the function bssgp_rim_ri_name_buf() must be
used.

BSSGP RIM messages are routed from a source to a destination cell by a
RIM routing information IE. Add parsing for the routing information and
support for relaying RIM messages to the destination cell/PCU. If the
destination cell/PCU is not directly connected to osmo-gbproxy route the
rim message to the first connected SGSN.

The MSC-pooling chapter in OsmoBSC mentions that overlapping NRI ranges will
warn if configured though the VTY interface, but fail when started with
such a config.
The manual for OsmoGbProxy promises a similar behaviour, this patch implements
it.

In BSSGP RIM the routing information IE is appearing twice (source and
destination). The current one dimensional TLV parsing method would only
give us access to the first routing information IE (destination), so
lets increase the dimension to 2, so that we get also IEs that appear
twice.

Instead of storing the raw ra_id in its unparsed binary form, store it

Let's simply copy this function over and become self-contained.
This would allow migrating osmo-gbproxy to a separate repository.

If a radio status message contains a TMSI it should be routed as if it
was a TLLI. Convert the TMSI to (foreign) TLLI so NRI-routing works.
Both foreign and local TLLIs are routed the same.

Some code was missing to support PAGING_REJECT and DUMMY_PAGING_PS over both PTP
and signalling. This commit adds the missing pieces, notably:
* Use and route according to the IMSI cache for paging on PTP
* Ensure DUMMY_PAGING_PS is broadcast if no routing area is included

When SGSN pooling is enabled we need to route some responses based on
IMSI back to the correct SGSN, e.g. PAGING_PS_REJECT.
The IMSI cache keeps track of this IMSI <-> NSE(SGSN) mapping.

When routing a SUSPEND/RESUME we need to keep track of where it came
from so we can send the (N)ACK back to the correct BSS. Use the TLLI
which is present in both messages to cache and retrieve the correct BSS.
A timer runs every two seconds and expires entries that are older than
the timeout (hardcoded to 5 seconds for now).
