gb_proxy: Add ctrl interface and nsvc-state, gbproxy-state commands
This patch adds a control interface to osmo-gbproxy as well as the first
two commands to query the state of each NSVC and gbproxy peer.
The "nsvc-state" command replies with
nsei, nsvci, local state, role, remote state of all NSVCs.
The "gbproxy-state" command replies with
nsei, bvci, mcc, mnc, lac, rac, and state of each peer.
Entries are separated by a newline '\n' character. If there are no
entries an empty list is returned. This behaviour is similar to that of
the subscriber-list-active-v1 command in osmo-sgsn.
$ ./osmo_ctrl.py -d 127.0.0.1 -p 4263 -g nsvc-state
Got message: b'GET_REPLY 23 nsvc-state 101,101,DEAD,BLOCKED,SGSN,DEAD,UNBLOCKED\n'
$ ./osmo_ctrl.py -d 127.0.0.1 -p 4263 -g gbproxy-state
Got message: b'GET_REPLY 4871085901306801158 gbproxy-state '

src: port openBSC over libosmo-abis
This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.

gb_proxy: Add ctrl interface and nsvc-state, gbproxy-state commands
This patch adds a control interface to osmo-gbproxy as well as the first
two commands to query the state of each NSVC and gbproxy peer.
The "nsvc-state" command replies with
nsei, nsvci, local state, role, remote state of all NSVCs.
The "gbproxy-state" command replies with
nsei, bvci, mcc, mnc, lac, rac, and state of each peer.
Entries are separated by a newline '\n' character. If there are no
entries an empty list is returned. This behaviour is similar to that of
the subscriber-list-active-v1 command in osmo-sgsn.
$ ./osmo_ctrl.py -d 127.0.0.1 -p 4263 -g nsvc-state
Got message: b'GET_REPLY 23 nsvc-state 101,101,DEAD,BLOCKED,SGSN,DEAD,UNBLOCKED\n'

enable telnet VTY bind address config for various programs
Following the 'line vty'/'bind A.B.C.D' command added in libosmocore, use the
configured address to set the telnet bind for the VTY line. It is now possible
to publish the VTY on a specific local interface (including 0.0.0.0 aka "any").
Implement in all of:
osmo-gbproxy
osmo-gtphub
osmo-sgsn
osmo-bsc
osmo-bsc_nat
osmo-bsc_mgcp
osmo-nitb
In some of these main programs, move the telnet initialization below the
configuration parsing.
Historically, this was not a good idea for programs using bsc_init.c (aka
bsc_bootstrap_network()), since they expected a gsm_network struct pointer in
((struct telnet_connection*)vty->priv)->priv, so that telnet had to be either
initialized or replaced by a dummy struct. In the meantime, the gsm_network
struct is not actually looked up in a priv pointer but in the static bsc_vty.c
scope (bsc_gsmnet), so this limitation is mere legacy (even though said legacy
is still there in an "#if 0" chunk).
In the other binaries I have briefly looked at the init sequence dependencies
and found no reason to initialize telnet above the config file parsing. In any
case, I have tested every single one of abovementioned binaries to verify that
they still parse the example config successfully and launch, allowing VTY
connections on the configured address(es). I hope this suffices.
In all of the above, log VTY address and port. LOGL_INFO is disabled by default
in some of the logging scopes, and since it is a single log message right at
program launch, I decided for the slightly more aggressive LOGL_NOTICE.
