 		004403c84d Implement F1 UE Ctxt Modif Transmission Action Indicator 
Implement the Transmission Action Indicator F1AP forwarding logic, and
add it to the F1 internal representation structure. After the
transmission interrupt timer (during which SRB1 can send messages), the
UE will be out-of-sync (we assume it's not there anymore).

Jaroslava Fiedlerova 3f51197548 Merge remote-tracking branch 'origin/fix-nssai-f1ap' into integration_2024_w42 (!3054) 
Currently, sD has not been allocated, so the octet string is empty. Fix the
allocation to correctly write&read NSSAIs in UE context setup/modification
request messages.

Robert Schmidt d5274af0ec Bugfix: correctly check for GTP initialization 
The existing check for the initialization of GTP is wrong; GTP returns
-1 if it could not initialize. Correct this, such that the DU will stop
if GTP cannot be initialize.

If we continue, the DU is requested to set up a GTP tunnel; because GTP
is not initialized, it assumes it is in monolithic/no F1, and does not
set up a tunnel. The F1 UE Context setup response encoder then fails
with this assertion:

    Assertion (tnl->teid > 0) failed!
