Instead of storing the raw ra_id in its unparsed binary form, store it
as a parsed struct. Also store the cell-id on cell allocation for later
use.

libosmocore yet. See OS#5009 for creating the proper first release.

Don't comment out the pdf glob, it works as intended when building the
package on OBS. I had disabled it, because with dpkg-buildpackage,
override_dh_auto_configure from debian/ruls gets ignored, leading to
--enable-manuals missing in ./configure, and to the pdf file not being
present. But apparently, dpkg-buildpackage just always ignores this,
it's the same with other Osmocom repositories.

Adjust the build system, packaging etc. to split osmo-gbproxy into its
own git repository. Remove tests and configs that aren't related to
osmo-gbproxy.

The call gprs_ns2_dynamic_create_nse has been removed because it
was a workaround for the old/dropped vty api.

Change the whole vty configuration for NS to be more flexible
and support more setups. Old configurations are invalid.

The last remaining functin of the SGSN code base we used was
gprs_gb_parse_tlli().
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.

The range of SUSPEND/RESUME timers T3/T4 is up to 10s so we should keep
the cache entries valid for this time.

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).
