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.

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.

This patch contains further work on several areas for the GMM layer,
like fixes and improvements in existing primitives, initial FSM
implementation, initial Tx and Rx of some GMM messages, etc.

The library itself only contains a bunch of boilerplate to build the
library and have usual initialization, logging, prim APIs.
There's not yet much logic specific in it yet, but will make next
commits easier to review.
