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.

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.

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

According to 3GPP TS 45.002, section 6.3.2.2.1, in the case of multi-
slot Uplink TBF allocation, a USF (Uplink State Flag) is given for
each PDCH allocated to the MS. Thus we need to indicate a USF value
for each PDCH to the lower layers: add ul_usf[8] to cfg_ul_tbf_req.
According to 3GPP TS 44.060, section 5.2.2, in the case of multi-slot
Downlink TBF allocation, a DL TFI (Temporary Flow Identity) given to
the MS is not limited to the scope of a single PDCH and applies to
all timeslots allocated. We're already doing this fine.

The comment above the invocation of configure_ul_tbf() suggests that
the lower layers need to be notified about the *release* of a tbf_nr.

As seen in TS 23.007 C.6.
We still don't need/want to implement ABM (acknowledged mode), hence
only the interface related parts are implemented, and transmit of SABM
message is left for the future.

This way we guarantee the llist object is always available even before
an XID.req is received (which may not be the case in NET mode).

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.

The DL_TBF for the assignment is not created until later on when the
DL_TBF is first used, only the DL_ASS request is stored as part of the
gpre->tbf_dl_ass_fsm.
Since no DL_TBF existed, the POLL was being stored if the DL_ASS
referred the UL_TBF by means of GlobalTFI->ULTBF.
Instead, let's not require an UL_TBF to be present and simply pass the
GRE along which can be used to send the PKT_CTRL_ACK later on when the
scheduling the poll triggers.
