The CellIdentifier IE of a BVC-RESET contains RA-ID and CID. We only
printed the forer, but not the latter. Let's fix that.

Prepare tracking the SDU from NS. Initialize with a conservative default.
The value is not yet updated, that will happen in a later patch.

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.

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.

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.

In order to support SGSN pooling we need to configure the various NRI
parameters such as the bitlen, NULL NRI, and which NRIs are assigned to
which SGSN.

* allow to print not only BSS-side BVCs, but also SGSN-side
* differentiate between SIG and PTP BVC
* print the actual BVC FSM state name instead of just UNBLOCKED/nothing

When there are multiple SGSNs inside a pool, we need to decide
how much of the per-BVC capacity advertised by the BSS in its
BVC-FLOW-CONTROL we should announce to each of the pool members.
A conservative approach would be to advertise 1/num_sgsn, but
there may also be use case where over-provisioning (announcing more
than an equal share of the capacity) is useful.
Hence, let's introduce "pool bvc-flow-control-ratio <1-100>" in order
to allow the administrator to decide.

Rewrite of a large part of osmo-gbproxy in order to prepare
for SGSN pool support. The amount of changes are of such fundamental
nature that it doesn't make sense to try to split this into hundreds
of individual changesets.

Those features were introduced a long time ago for one specific use
case at one specific user, and they are not needed anymore. They
complicate the code base significantly and are hard to maintain with
all the upcoming modifications regarding SGSN pool supoprt.

We will soon also have a list of sgsn-side NSEs, and we need to
differentiate those.

I cannot really read the code while it contains its historical weird
naming. A "peer" used to be a strange amalgamation of NSE + BVC,
while in reality we can have any number of BVC on top of each NSE.
We recently started to split the peer into a gbproxy_nse_peer + gbproxy_peer.
This takes it one step further and renames gbproxy_peer to gbproxy_bvc,
as that's really what it is.

The gbproxy_nse is created when the signalling BVC is resetted. When
we delete all bvcs of an nsei we need to remove it as well.

Since gbproxy doesn't use bssgp_rcvmsg from libosmocore we need to
implement our own filtering.

We want this level of indirection to support multiple BVCs per NSE. The
current code assumes that an NSE only has one BVC which breaks messages
on the signalling BVC which should only be sent once to an NSE
regardless of the number of BVCs it contains.

Since NS2 has a different abstraction we mock up the prim send/recv
