The MS do not show the USSD messages yet. This patch modifies the
implementation to insert a CM Service Accept to finish the
establishment of the MM connection according to 3GPP TS 04.10/3.2.1
before the USSD notification is sent.
This fix has been tested with a Blackberry phone that has shown
an ussd_grace_txt after rf_locked has been set to '1'. Without this
patch, that message wasn't shown. The phone has sent a CC Setup
and other messages before processing the channel release message sent
by the BSC, but these messages have not been forwarded to the MSC (as
expected).

Send an USSD message to the mobile station requesting a connection
for a call or a SMS when the link to the MSC is down or in the
grace period.
The messages can be set (and this feature activated) by setting
bsc/missing-msc-text resp. msc/bsc-grace-text via the vty.
The generation of both messages has been tested manually.

Handle the mr_config request and set the AMR multirate config for
the given MSC. Initialize the mr_config with the AMR5.9 default we
have been using until now.
When we are asked to route calls on a local link and
the link is not available we would crash when trying
to send a packet over a deadline. When we have decided
to move a connection it is guranteed that the current
SCCP connection will vanish, we either migrate to another
MSC or the RSL/subscriber connection will be closed.
Inspect the CC Setup messages and if the dialed number is matching
the regexp of the local MSC the connection will be rerouted. The
original MSC will get a GSM0808 CLEAR REQUEST, a new connection with
a CC Setup message will be opened.
We want to have multiple MSCs but we also have some data
that is only present on a per BSC basis. Right now the
MSC data is not allocated with talloc, so we have some
change in the talloc contexts.

osmo_bsc_api.c:193:28: warning: unused variable ‘sccp’ [-Wunused-variable]
When we got a clear request we did not clear the internal
association between the gsm_subscriber_connection and the SCCP
part. When we got a DTAP message before the CLEAR COMMAND we
will end up in a crash as the ->bts pointer of the connection
has been cleared.

When the BSC is refusing to open an outgoing connection the SCCP
connection was leaked. Use the normal free as the socket should
be either closed or disconnected.
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]

The new structure divides the code into a number of libraries
for the BSC core functionality, MSC core functionality, Abis transport,
TRAU and other bits.
This doesn't introduce any functional code change but simply moves
around files and alters Makefile.am accordingly.
Next step would be to disentangle a lot of the inter-library
dependencies and make the individual bits of code more independent.
