Max cf307fb8ff Move channel state assignment to macro
Previously we've used function so debug print always pointed to the same
place which is not very useful. Replace it with macro so proper
file:line is printed. Also, make sure that we always change state only
through this macro.

Harald Welte a43e0b4d9a Use libvlr in libmsc (large refactoring)
Original libvlr code is by Harald Welte <laforge@gnumonks.org>,
polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>.

This is a long series of trial-and-error development collapsed in one patch.
This may be split in smaller commits if reviewers prefer that. If we can keep
it as one, we have saved ourselves the additional separation work.

SMS:

The SQL based lookup of SMS for attached subscribers no longer works since the
SQL database no longer has the subscriber data. Replace with a round-robin on
the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the
subscriber is currently attached.

If there are many SMS for not-attached subscribers in the SMS database, this
will become inefficient: a DB hit returns a pending SMS, the RAM lookup will
reveal that the subscriber is not attached, after which the DB is hit for the
next SMS. It would become more efficient e.g. by having an MSISDN based hash
list for the VLR subscribers and by marking non-attached SMS recipients in the
SMS database so that they can be excluded with the SQL query already.

There is a sanity limit to do at most 100 db hits per attempt to find a pending
SMS. So if there are more than 100 stored SMS waiting for their recipients to
actually attach to the MSC, it may take more than one SMS queue trigger to
deliver SMS for subscribers that are actually attached.

This is not very beautiful, but is merely intended to carry us over to a time
when we have a proper separate SMSC entity.

Introduce gsm_subscriber_connection ref-counting in libmsc.

Remove/Disable VTY and CTRL commands to create subscribers, which is now a task
of the OsmoHLR. Adjust the python tests accordingly.

Remove VTY cmd subscriber-keep-in-ram.

Use OSMO_GSUP_PORT = 4222 instead of 2222. See
I4222e21686c823985be8ff1f16b1182be8ad6175.

So far use the LAC from conn->bts, will be replaced by conn->lac in
Id3705236350d5f69e447046b0a764bbabc3d493c.

Neels Hofmeyr 218e4b4aa0 move openbsc/* to repos root
This is the first step in creating this repository from the legacy openbsc.git.

Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.

Holger Freyther 3aa8d6c46d [paging] This is paging my phone but it looks completely wrong...
- The paging block calculation is wrong but I have a hard time finding
  the right information. The table of 05.02 (Table 5 of 9) looks good
  but my phone is not happy with that group...

Holger Freyther 2976c40cd1 [paging] Allow call the paging related helper functions
they alread had external linkage

Holger Freyther b01554493f [rsl] Prepare to properly handle the paging command add defines to the RSL
For finding the right paging group one needs to know various
settings that are broadcasted as part of system settings 3. This
includes the CCCH Conf, the BS_PA_MFRMS, BS_AG_BLKS_RES.... The
next step will be to move away from the hardcoded System Settings 3
so one can calculate the paging group...

The actual paging by subscriber needs to be implemented

Holger Freyther 67b4b9a017 Do not call rsl_chan_release directly but use the use_count of the lchan
Call use_lchan early in allocate_loc_updating_req, do not directly call
rsl_chan_release but go through channel alloc to take the use_count into
account.
