bsc_api: Move gsm48_rcvmsg into the BSC API and dispatch.
...
The next step in the way to the BSC API. We have a clear a
new connection was opened signal now... and the MSC could
use it...

bsc_api: Make paging/silent call work with the subscriber_connection
...
Do not use the lchan for the paging but operate on the
subscriber_connection, change the signals too to not carry
the lchan but the subscriber connection... the silent call
and vty code still assume there is a lchan inside the
subscriber connection.

bsc_api: Move BSC API between MSC and RSL code...
...
The lowlevel BSC paging API is a simple wrapper around
the RSL command. The BTS will automatically repeat these
messages but if we end up with two MSC inputs we will
need to count these messages somewhere...

si13: Use the correct pseudo length for the SI13 message
...
The GSM04.08 Section 10.5.2.19 specifies the L2 Pseudo Length
and the length does not include rest octets, so we will need
to use a zero for the length.
The patch is coming from Dieter Spaar.

nat: Allow to specify multiple entries in the access-list...
...
Inside the access-list we have a list of entries that have
either one allow or one deny rule... we do not allow to remove
a single rule but one has to remove the whole list, in that case
talloc will handle cleaning all entries.
Right now the matching is O(n*m) as we traverse the list
(multiple times) and run the regexp multiple times. One
way to make it faster would be to concat all regexps into
one.

[nat] Introduce the concept of access-list
...
One can set one access-list to one BSC and one
access-list to one NAT. The matching of IMSIs
remains the same for now, also applying the
white/blacklist. Access lists can not be deleted
for now and no perf opt is done (e.g. one could
cache the result of the last lookup in the bsc
struct).

[nat] Add the notion of a "local" connection.
...
A local connection is only between the MUX and the real BSC. We will
not forward anything to the MSC. This will be needed for the IMSI
filtering as sending a CREF is not liked by every BSC...

[nat] Do not access the con after the removal

In case of a RLC message we will destroy the SCCP connection. This means
that accessing the con and con->bsc will access old memory. Keep the status
local and move the con into an inner scope.
