The "Radio Priority" received in GMM Attach Accept are for SMS and TOM8
SAPs only. For GMM/SM unitdata transferred to LLC, use highest
radio_prio=1.

TS 24.007 and TS 24.008 seem to lack providing an explicit way to pass
information between GMM and SM (GMMSM interface) when a RAU process
happens in GMM (rx RAU Accept).
This lack of primitive can easily be spotted by looking at TS 24.007
Appending C.15, or even better, at the 3rd page of "C.16(cont’d)" around
the "STOP Trams" timer, where the info is magically available in SM when
being received at GMM.

This can be used for users receiving the GMMRR_ASSIGN_REQ primitive to
find out if it's a creation, update or deletion of a TLLI.

This even is triggered by the GSM itself due to internal timeouts as a
consequence of lower layers not resolving the request (with accept or
reject events).

Basic implementation of gprs_gmm_decode_network_name() was cherry-picked
from osmocom-bb 2dfa84e73dca455900e6522f61f5c610077783b7
decode_network_name().

This information will be needed once the GRR layer starts listening for
paging requests, which identify MS by either PTMSI or IMSI.

This event doesn't show up as an explicit primitive in TS 24.007 GMMRR
SAP, but it is clearly needed to (re)arm the READY timer in GMM layer as
per TS 24.008 section 4.7.2.1.1:
"""
The READY timer is started:
- in the MS when the GMM entity receives an indication from lower layers that an LLC frame other than LLC
NULL frame has been transmitted on the radio interface;
"""

3GPP TS 44.064 loosely defines "QoS params" on each primitive by listing
the fields, which are a bit different on each primitive.

Upper layers (SM or app) may need access to PTMSI or TLLI.
PTMSI:
- App may want to store it somewhere in order to reuse it next time
it wants to GMM Attach.
TLLI:
- App will need the TLLI to identify the MS when sending/receiving
primitives over SN SAP (app<->SNDCP).
- SM layer will need the TLLI to communicate over SNSM SAP (SM<->SNDCP),
as well as relay the information to the app if the GMM Attach happens
implicitly over SMREG-Act_Pdp_Ctx.req -> GMMSM-Establish-Req.

Newer gcc errors about "cause" being uninitialized, but cause is
guaranteed to be set in the "case GPRS_GMM_MS_EV_LOW_LVL_FAIL" path, it
just fails to find out.
Since the approach used previously is a bit hacky, let's simplify it.

The GMM layer doesn't really have to differentiate between SM
connections, everything is sent over the LLC "GMM" SAPI.
However, we still want to identify/related a given MS if there are
multiple MS using the stack.

Update the state in the FSM before triggering paths implemented by the
user which may also again interact with the FSM. If the state is not
updated earlier, then the new interactions may encounter the FSM in an
unexpected state with regards to the event received.

New GMM-GMMREG-SIM_AUTH.ind/rsp primitives are added to allow GMM
resolving authentication request received from the network.
The user of the GMMREG SAP is responible for doing the resolution using
its SIM.

Otherwise if a test includes {layer_name}_private.h from several
libraries to use private APIs it will fail due to colliding g_ctx
pointers of different types.

This patch itnroduces all the boilerplate required to build and package
a new libosmo-gprs-sm.so library, which aims to contain the SM layer
implementation.
A minimal implementation is provided together with a unit test,
showcasing Activation of a PDP Context and requesting implicit GPRS
attach to GMM if it is not yet attached.
This commit also adds/improves code in GMM layer implementing the GMMSM
SAP which is used to interact SM<->GMM.
