Andre Puschmann a4abd96ab6 nas: use MME security header when receiving identity request 
this basically avoids sending a integrity protected or ciphered
identity response to a plain identity request

Andre Puschmann 057844d7d6 signal_handler: increase alarm timeout to 5s and use raise instead of exit() 
it seems that exit() causes problems when threads couldn't be stopped
properly, which is the reason why we have to call alarm() in the first place.
therefore, send a SIGKILL to our process and make sure we don't leave any
zombie threads running.

Andre Puschmann d69aa55a42 enb: don't exit enb if rr.cfg for 6 PRBs isn't correct 
we agreed to print the error message but still patch the values to
work for 6 PRBs. Since there is only one option there is not
configuration ambiguity.

Andre Puschmann 9f4e1ba62d srsepc: use received NAS count to calculate MAC 
this is according to 24.301 Sec 4.4.3.3 which says the receiver
should use the sequence number included in the received message
rather a local estimate

Andre Puschmann acc2948b45 nas: fix security handling 
First of all, with this the NAS conformance tests pass with ciphering and
integrity turned on. Before only integrity was working.

Mainly the NAS was applying the integrity protection and/or ciphering
incorrectly because it wasn't taking the secuirty status of the PDUs
into account. Some where already correct, some not. The patch
streamlines the handling for all outgoing messages.

Andre Puschmann 62e4bd9469 log_ptr: fix issue if accessing log_ptr that was reset already 
during deinit of the UE/eNB it could happen that the log_ptr
was already set to null but the stack thread was still accessing
it through log_h->info()

i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them

Andre Puschmann f477c1d2e5 nas: allow starting a attach request procedure even if a PLMN is already selected 
previously the NAS would cancel a attach request procedure if the PLMN
is already selected. PLMN selection, however, in not necessarily happening
before requesting RRC to establish a connection.

Andre Puschmann 94c6034339 nas: rename start_attach_request to start_attach_proc 
this is to better differentiate from "send_attach_request" that
only packs and send the actual attach request message. The
entire attach procedure may include PLMN search, etc.

Andre Puschmann d0480141e5 nas: move re-arming and stopping of attach request related timers 
t3402, t3410 and t3411 are now managed in the sender
function of the attach request. previosly they were only
correctly started in the high-level NAS call start_attach_request()
which may not be called if NAS itself resends the request
