Andre Puschmann f31a7d1d02 epc,nas: add handler for PDN connectivity request 
COTS phones seem to send standalone PDN connectivity request
messages even after the initial attach was complete. We don't fully support
them in the EPC but instead of logging a warning we can just send
a reject at least to keep the logs clean.

Pedro Alvarez f9a2850d74 gnb,ngap: Added interface so the NGAP can pass a NAS message to the RRC 
upon starting the RRC Security Mode command. This allows the gNB to
pass this message only after the SM procedure is complete.

Also made sure that the RRC notifies the NGAP upon the end of the
reconfiguration procedure, to make sure that the NGAP sends the UE
context setup response.
