Add the control interface with no hierachy right now and implement
the first command to list IMSI + Context Address of active sessions.
sgsn_cmd_handle could share more code with bsc variant.
Fixes: SYS#264, SYS#265

elements.
Original code was inconsistent about lengths and could lead to out
of bounds write. Lengths were also inconsistent with the TS 24.008.
Fixes: Coverity CID 1040714.

The MS Radio Access Capability IE can be _very_ long in some recent
high-end mobile phones, way beyond the old 14-byte limit. We increase
our array to 52 bytes, and make sure not to overflow that buffer.

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]

If the GGSN restarts, its restart counter will increase. We can
detect that and accordingly release/delete all PDP contexts for
that GGSN.

* separate the LLME and LLE state in the LLC layer
* introduce gprs_llgmm_assign() function for LLGMM-ASSIGN.req primitive
* change QoS profile to match 'real' SGSN
* Update the new TLLI when assigning a P-TMSI
The result now is that the LLC layer is notified of TLLI changes, which in turn
means it doesn't allocate a new LLE structure every TLLI change, which again
in turn means that the UI frame sequence number does not reset to zero.
As a result, MS should no longer ignore frames based on wrong UI sequence number.

Our state transitions and timers now reflect 04.08 for GMM much
better than before. Also, we allocate a new P-TMSI on every ATTACH
and RA UPDATE, as some phones seem to get confused if they don't
get a P-TMSI.

* store LLC SAPI as part of PDP ctx
* store NSEI + BVCI as part of MM ctx
* export gsm48_tx_gsm_act_pdp_acc() and call it from sgsn_libgtp.c
* create and use gsm48_tx_gsm_act_pdp_rej for error cases
* print SAPI as part of VTY show pdp

We never want to support multiple sgsn's within one process, so
there is no point in passing them around all the time.

libgtp of the OpenGGSN project will allow us to speak the GTPv0/v1
protocol of the interface between SGSN and GGSN.
This commit includes code for the main libgtp integration (file
descriptor, select loop, timer) as well as code to encode/send
a CREATE PDP CONTEXT request.

libosmocore already uses them, it's time (at least for new code)
in openbsc to do the same.

This branch contains the partial SGSN/GGSN implementation that
was originally developed as part of the gprs branch.
