Supporting GPRS means we have a number of additional OML objects to
deal with. We need to extend our gsm_bts structure to at least
include the nm_state for each of those objects.
Add support for 1900 nanoBTS by using unified bts_type
GSM_BTS_TYPE_NANOBTS for 900, 1800 and 1900 versions.
Reduce the nanoBTS enum values to one and derive the
version from the user supplied band. In the future we
might want to do auto band detection.
The configuration file needs to be changed to refer
to nanobts instead of nanobts900/nanobts1800.

The LAC can be 16bit of size. the generation of the LAI, struct
gsm_subsriber and the BSC<->MSC was already using it as a
16bit (short) value.
Change struct gsm_bts to parse 16bit and change the vty configuration
parsing code to deal with a short too.
Transfering the cell_identity from BSC to MSC is required for the
on-waves.com support. Allow to set the cell_identity in the cfg
file and patch the system information tables to set it.
This just adds the 04.08 and RSL bits for A5, but not the logic
for performing authentication.
The caller would first set lchan->encr and then call
gsm48_send_rr_ciph_mode(lchan), which encapsulates the 04.08
CIPHERING MODE COMMAND into a RSL ENCRYPTION COMMAND and sends it
to the BTS for execution + forwarding.
The channel allocator can be set in ascending or descending order.
Ascnending means we first try to allocate channels on TRX0, then TRX1, etc.
Descending means we first try to allocate cahnnels on TRXn, then n-1 down to 0.
we now have the full path from the MS into the database (SUBMIT), as well as
back from the database to the MS (DELIVER). The database gets correctly
updated once a SMS has been successfully delivered.
What's still missing is the periodic scan over all undelivered messages,
trying to deliver them to the respective MS. So far, you have to manually
trigger this on the telnet interface with 'sms send pending 1'
* we only need one piece of code to calculate rsl_ie_chan_mode from
our run-time data structures (gsm_lchan)
* add some more channel modes for TCH/H and data
* use enum's to make the compiler warn us about unhandled enum values
* make sure the caller determines the (signalling,speech,data) mode
Up until now, we only supported direct RTP streams between ip.access BTS.
With this commit, the user can specify '-P' to the command line to enable
a RTP/RTCP proxy inside OpenBSC. The nanoBTS will then send all their voice
data to OpenBSC, which will relay it to the respective destination BTS (which
can be the same BTS).
The default behaviour remains unchanged. Without '-P' on the command line,
RTP/RTCP is exchanged directly.
Since a transaction is associated to a gsm_subscriber, and the subsciber
is part of a network, we don't need to have a dedicated transaction->network
pointer.
This changeset factors out gsm_transaction as something independent
of call control in preparation to re-use the code from SMS. A
transaction is uniquely identified by either its callref, or by
a tuple of (transaction_id, protocol, subscriber).

* describe data structures in gsm_04_11.h
* increae LCHAN RELEASE TIMEOUT for case of long SMS
* convert header field in sql table from NUMERIC to BLOB
* initial handling for validity period
* send RP ERROR messages with meaningful RP CAUSE in case of error
* add bts->band field plus corresponding VTY and commandline argument
* add trx->nominal_power and trx->max_power_red fields
* add rsl_chan_bs_power_ctrl() to control TRX RF power for a given TS
* add rsl_chan_ms_power_ctrl() to control MS RF power for a given lchan.
This is Harald's reworked MNCC base, slowly heading towards integration
into master. The key changes are:
* provide much more structure to the data in gsm_mncc
* encode_* and decode_* functions now take a structure rather than tons
of individual arguments (whose order nobody can remember)
* make sure we don't have copies of the same code everywhere by introducing
mncc_set_cause() and mncc_release_ind()
* save horizontal screen space if possible
* make sure we break lines > 80 characters
Implement subscr_get_channel and subscr_put_channel to
a degree that SMS Submit and phone call scheduled at the
same time will deliver both (one after the other).
