App and SM itself 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.

At that point in time we may still need it, for instance to send the
primitive to the upper layers. Still, we want it to be t the correct
state when that happens. Hence, delay freeing the object to happen in
next loop iteration, so that it is still available to submit the
primitive, and even skip freeing the object if the SM SAP user decides
to re-activate the PDP context in a synchronous code path from the
primitive callback.

There's no use in keeping them in inactive state.
This allows upper layers recreating them upon next SMREG-PDP_ACT.req.

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.
