Sylvain Munaut 5a86e06eb3 auth/ciph: Enable securing of channel directly after paging response 
This protects MT services

Sylvain Munaut 0fbfd1bb52 gsm_04_08: Make gsm48_secure_channel available globally 
Can't declare it in gsm_04_08.h tough ... gsm_cbfn is defined in
gsm_data.h and trying to include that in gsm_04_08 just creates a
huge mess.

Sylvain Munaut e0b06b0293 bsc: Allow to configure Optional Cell Selection params from vty 
The default values are those where the parameters are encoded
as '0' and they're not output in the config file if that case

Make the USSD welcome text configurable.

Holger Hans Peter Freyther cf6f71aa7f mid-call: Make the mid-call behavior the default for switching things off 
When switching the RF off we will always go through the grace
period, add a direct off mode to switch it off directly. Make
the query return a 'g' if we are in the process of switching
things over.

Holger Hans Peter Freyther 70c232f75a mid-call: Implement a timer to go from grace to off. 
Start the timer... switch it off when we do the final
tranistion by a command.

Holger Hans Peter Freyther d283db496f vty: For ipaccess we will dump if the OML connection is present 2010-11-26 00:00:22 +01:00
Holger Hans Peter Freyther dab8e27755 ipaccess: Fix dropping the OML/RSL connection. 
Use the ipaccess_drop_oml and ipaccess_drop_rsl functions
instead of closing the socket and hoping this is picked up
somehow. This just leads to some weird hangs. And gdb was
not really helpful to say where it was coming from.

Holger Hans Peter Freyther 9c838ae069 bsc: Implement paging by creating a dummy subscr for the paging 
In the future we should avoid using a gsm_subscriber at all
and pass the imsi/tmsi to the paging function directly. For
now we can use the old model for paging and go through the
gsm_subscriber. This has the benefit of load balancing on
the BTS and such.

Holger Hans Peter Freyther b79c3c97a2 bsc: The ip.access rtp-payload has no useful meaning 
Sending this as the RTP_PAYLOAD2 will produce a MDCX NACK
as we send the RTP_PAYLOAD in the CRCX. It does not seem to
be necessary to send anything != 0 for the RTP_PAYLOAD2.

Holger Hans Peter Freyther 863a55d44d bsc: Make bsc_queue_for_msc work on the osmo_bsc_sccp_con 
The gsm_subscriber_connection can die before the SCCP connection
so we should work on the osmo_bsc_sccp_con.

Holger Hans Peter Freyther 890dfc58ed bsc: Work on paging and parsing other messages 
The paging is not implemented due bad/missing API in the
BSC API, the rest are simple stubs to be merged from the
on-waves/bsc-master.
