gbproxy: Handle old and new P-TMSI/TLLI

Don't replace the current TLLI immediately, store it in an additional
'assigned_tlli' field and discard the old TLLI when both sides have
used the new one (see GSM 04.08, 4.7.1.5).

Add an Attach Complete message to test and check, whether the related
field of the corresponding tlli_info struct are set as expected
during the local TLLI validation cycle.
