Daniel Willmann 5f762597e5 gbproxy_ctrl: Ignore SIG-BVCI in ctrl commands
Both ctrl commands gbproxy-state and number-of-peers should only
operate on PtP-BVCs. This patch avoids a crash in gbproxy-state and
fixes the count of number-of-peers to only include PtP-BVCs.

Daniel Willmann 5e8c0e813c gbproxy_ctrl: Fix crash in nsvc-state ctrl command
ctrl_nsvc_state_cb() expects us to pass a struct nsvc_cb_data so do that
instead of passing only the ctrl_cmd.

Philipp Maier da3af94bf8 gb_proxy: simplify raid data storage
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.

Philipp Maier 55a22b8bc0 gb_proxy_ctrl: use mcc-mnc-lac-rac notation instead mcc,mnc,lac,rac
The notation for the RAI used in the log is not compliant to the spec.

Oliver Smith 29532c2a06 === Split osmo-gbproxy from osmo-sgsn ===
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.

Harald Welte e520964dc2 gbproxy major rewrite for SGSN pool support
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.

Harald Welte 7a0c9ddab0 gbproxy: Remove patching, TLLI-tracking and SGSN2 support
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.

Harald Welte 8b4c794679 gbproxy: convert nse->bvcs from llist_head to hashtable
For the common lookup-by-bvci, this should reduce the computational
complexity significantly.

Harald Welte 2b7b1bbbdc gbproxy: Rename gbproxy_cfg.nses to gbproxy_cfg.bss_nses
We will soon also have a list of sgsn-side NSEs, and we need to
differentiate those.

Harald Welte 560bdb37cc gb_proxy: Rename gbproxy_peer to gbproxy_bvc
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.

Daniel Willmann e50550e409 gbproxy: Add NSE peer that can have multiple gbproxy_peers
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.

Alexander Couzens 951e133d17 Port gbproxy to NS2
Since NS2 has a different abstraction we mock up the prim send/recv
functions and don't test NS like the old tests did.
