tests: don't hardcode length values of expected encoding gsm_7bit_encode:
...
make sure to return the number of actually written bytes gsm_7bit_decode:
calculate length of resulting septets from input length before decoding
The input length to gsm_7bit_decode reflects the number of encoded bytes
to be decoded. As the decoding is done on the input in septetes we need
to take this into account and recalculate the length.

[GPRS] BSSGP/SGSN: Implement Gb-Interface Paging
...
We now have a function that generates BSSGP PS and CS paging request.
It is called from the libgtp code when we receive a GTP packet from
the GGSN for a MM context that is in SUSPEND state. We then issue
a PS paging request to the Cell with the BVCI where the last RA update
was being performed.
TODO: We still don't enqueue the GTP packet (and transmit it on paging
complete), and we don't rate-limit the paging requests, i.e. every GTP packet
will trigger another paging request.
We probably also need some kind of logic that marks the phone as UNREGISTERED
if it doesn't respond to paging requests for some time.

[GPRS] Major LLC / TLLI handling fixes
...
* 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.

a pointer to the MM ctx from GMM through LLC into BSSGP :(
