This introduces a new LOGP() macro together with LOGL_* definition to
support multiple log levels (severities) throughout the codebase.
Please note that the actual logging system does not use them yet,
in this patch we simply introduce the new macros at the caller site.
With this commit, we can successfully hand over a channel from one cell to
another cell. We implement asynchronous intra-BSC (but inter-BTS) handover.
Changes:
* introduce new DHO log category
* extend rsl_chan_activate_lchan() with argument for HO reference
* introduce actual minimal handover decision making in handover_decision.c
* various fixes to bsc_handover_start() in handover_logic.c
Before this commit, OpenBSC used templates for the SYSTEM INFO
1, 2, 3, 4, 5 and 6 messages. Those templates were patched in
various places to reflect the network config like ARFCN.
Now, we actually generate those SI messages ourselves, using
values from the configuration file, and even calculating neighbor
cell lists.
All bts'es that you have configured in OpenBSC will end up in
the neighbor cell list - which should be more than sufficient for
the current small-single-site networks.
- Make sure that on runtime the Radio Carrier can be
locked and unlocked. The vty code calls into the
Abis NM to lock/unlock the channel and the state is
stored there.
- Make sure that on start the Radio Carries remains
offline and we are not starting it. On start the
radio carrier is either locked or unlocked. This means
the RSL will not connect until the RF is unlocked. It
will connect then. To see RSL bringup failures one
needs to parse the RSL nack message.
- When the TRX is locked on startup the RSL link will
only be established after it will be unlocked.
On cold start the RSL link will not be brought up. Wait for the
Software to be Activated before starting the RSL link. This is
working reliable on the BTS I have tested with.
This is a partial revert of 8406ec2437 and
was discussed on the mailinglist.
bsc_init.c still contained a hard-coded channel configuration,
i.e. CCCH_combined on TS0 of C0, and TCH/F on all other channels.
Now it correctly uses the value as specified in the config file.
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.

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.
Do not advertize to broadcast on a different frequency, this
was only useful for the HAR2009. The frequency list of the cell
probably needs to migrate into the vty config file.

Share the initialization and bootstraping of the network by moving
the code to a new file and making boostrap_network and shutdown_net
external.
Cleanup the header list after the move and remove trailing whitespace.
