libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

This patch fixes:
CC gb_proxy_main.o
gb_proxy_main.c: In function ‘main’:
gb_proxy_main.c:224: warning: implicit declaration of function ‘logging_vty_add_cmds’
And a similar problem in osmo-bsc_nat.
This was introduced in by myself in patch:
"bsc: change bsc_vty_init to take logging categories as parameter"

The reason for this is quite simple: We want to make sure anyone
running a customized version of OpenBSC to operate a network will
have to release all custom modifiations to the source code.
This uses the osmo_daemonize() function of libosmocore >= 0.1.18,
and is now implemented for bac_nat, osmo-bsc, bsc_hack, osmo-gbproxy
and bsc_mgcp. This means only osmo-sgsn is missing, which currently
has no option parsing at all.
Almost all parameters about the SGSNs NS-VC can be specified in the NS
protocol node. All that needs to remain in the gbproxy config node
is "nsip sgsn nsei XXX".
We want the VTY and telnet code to be independent from the BSC
application(s). As a side note, we also like to eliminate static
global variables for 'struct gsm_network' all over the code.
As such, telnet_init() is now passed along a "private" pointer,
which getst stored in telnet_connection.priv. This telnet_connection
is then stored in vty->priv, which in turn gets dereferenced if
anyone needs a reference to 'struct gsm_network' from the BSC vty
code.
Also:
* vty_init() now calls cmd_init()
* the ugliness that telnet_init() calls back into the application by means of
bsc_vty_init() function has been removed.
* telnet_init() now returns any errors, so the main program can exit
e.g. if the port is already in use.
This enables us to make the VTY completely independent of any
compile-time program-specific information, i.e. one step closer
to using VTY as a shared library from multiple programs.
Some BSS that connect to the proxy do not continue to perform the
RESET procedure after a timeout. In order to resurrect them, we
simply start a RESET procedure.
Every NS-VC now has a set of counters for incoming and outgoing
number of packets and bytes.
We also split the VTY part of the gprs_ns.c implementation into gprs_ns_vty.c
to make sure the protocol can actually be used without the VTY code being
present.
With persistent NS-VC configuration (configured through VTY),
we can respond properly to BSS with a somewhat strange NS
implementation Such as the BSplus. It enables us to respond
with a proper NS-RESET (including NSVCI/NSEI) when receiving
a NS-ALIVE or other PDU for a BLOCKED/DEAD NS-VC after our
end of the connection is rebooted.
In order to reuse the existing bssgp_tx_* functions without pulling
in the dependencies of gprs_bssgp.c, we have to move those functions
to gprs_bssgp_util.c
Furthermore, we can remove gbprox_nsi and replace it with bssgp_nsi,
and we can do proper processing of BVC-RESET messages coming from
the SGSN on the signalling BVC. In that case we need to send RESET
messages to all the BSS.
