54f5352e07 nat: Close SCCP connections when the USSD Provider is closed. 
Send a RLSD down to the BSC in case the USSD Provider is gone. It
is not sending a Clear Command and ut depends if the BS+ will
like this kind of behavior. At least the data on the NAT will
be freed soon afterwards due the RLC message.

07dfc70276 nat: Make clear where the RLSD is send to 
Add a _msc to the method as we will send a RLSD to the
MSC and will add a method to send it down to the BSC
as well.

0586b0fa47 [vty] First set of fixes for the oml/rsl con dropping 
The code had wrong documentation in the VTY, it crashed
when OML or RSL was not up yet. These issues are fixed
right now.

2484ceb2be [vty] Add ipa specific command to provoke failures to test OML/RSL reconnect 
We need to simulate OML/RSL failure in an easy and fast way
and adding a command to do so seems like a good way to achieve
this. The command is a bit misplaced, in one way it is no config
and does not belong into the config node but then again it does
not belong into the VIEW_NODE either as it is manipulating content.

On this merge I have changed it to the ENABLE_NODE.

Extract the IMSI from the first message as well and safe it
in the connection structure. The problem is that we do not
have this structure at this point, so we will allocate the
imsi as child of the bsc_connection and then move/steal it.

Split the trace based on SCCP Connections, in case an error is
detected, the trace will be stored instead of being deleted and
the full log can be viewed afterwards.

Right now only LU Rejects are recognized, but this can be extended
to other things as well.

1fd60631f7 nat: Change the order of the DENY/ALLOW rule for the BSC. 
Currently it is not is not easily possible to disable
everyone and then only allow certain SIMs. By changing
the order we can do:
	access-list imsi-deny  only-something ^[0-9]*$
	access-list imsi-allow only-something ^123[0-9]*$

and still keep the usecase of only forbidding certain
SIMs on certain LACs. Adjust test case, test that the
other cases are still functional.
