Filtering by IMSI in osmo-bsc is a legacy use case with questionable
usefulness. Remove.
Do not keep deprecated VTY commands: those could be dangerous, since
(presumably non-existing) users might assume that the filtering would still be
in place. Rather fail to start osmo-bsc for config with an IMSI ACL.
The IMSI filtering did, if present, provide the logging with an IMSI to print
for the bsc_subscriber. TMSIs should have ended up in logging likewise, which
has never been implemented. The proper way to learn the IMSI would be by the
Common Id message from the MSC. Furthermore, the upcoming MSC pooling feature
will extract the mobile identity again, and will hence make sure that both IMSI
and TMSI identities, as available, end up in the bsc_subscriber and will be
logged again.
So long, IMSI ACL, and thanks for all the fish.

Move all of libbsc/ into osmo-bsc/, and separate/move some implementations to
allow linking from utils/* and ipaccess/* without pulling in unccessary
dependencies.
Some utilities use gsm_network and gsm_bts structs, which already include data
structures for fairly advanced uses. Move initialization that only osmo-bsc
needs into new bsc_network_init() and bsc_bts_alloc_register() functions, so
that the leaner tools can use the old gsm_* versions without the need to link
everything (e.g. handover and lchan alloc code).
In some instances, there need to be stubs if to cut off linking "just before
the RSL level" and prevent dependencies from creeping in.
- abis_rsl_rcvmsg(): the only program currently interpreting RSL messages is
osmo-bsc, the utils are merely concerned with OML, if at all.
- paging_flush_bts(): ip.access nanobts models call this when the RSL link is
dropped. Only osmo-bsc actually needs to do anything there.
- on_gsm_ts_init(): the mechanism to trigger timeslot initialization is related
to OML, while this action to take on init would pull in RSL dependencies.
utils/ and ipaccess/ each have a stubs.c file to implement these stubs. Tests
implement stubs inline where required.
From src/utils/, src/ipaccess/ and tests/*/, link in .o files from osmo-bsc/.
In order for this to work, the osmo-bsc subdir must be built before the other
source trees. (An alternative would be to include the .c files as sources, but
that would re-compile them in every source tree. Not a large burden really, but
unless linking .o files gives problems, let's have the quicker build.)
Minor obvious cleanups creep in with this patch, I will not bother to name them
individually now unless code review asks me to.
Rationale:
1) libbsc has been separate to use it for osmo-nitb and osmo-bsc in the old
openbsc.git. This is no longer required, and spreading over libbsc and osmo-bsc
is distracting.
2) Recently, ridiculous linking requirements have made adding new functions
cumbersome, because libbsc has started depending on osmo-bsc/*.c
implementations: on gscon FSM and bssap functions. For example, neither
bs11_config nor ipaccess-config nor bts_test need handover_cfg or BSSMAP
message composition. It makes no sense to link the entire osmo-bsc to it, nor
do we want to keep adding stubs to each linking realm.

Move gsm_data.c and handover_cfg.c to libbsc, where they belong.
This leaves libcommon utterly empty, drop it.

There still is a lot of dead code that we inherited from the NITB
days, let's remove more of it.
libtrau will be re-introduced as part of osmo-mgw later.

* check GPRS state: if GPRS is enabled for the BTS but NSE, CELL or both
NSVC are locked than report it as degraded
* check TRX usability: use already available function to check that TRX
is actually usable when reporting OML status via CTRL
* fix tests linking: libbsc is using gsm48_create_mm_serv_rej() which is
defined in libcommon-cs but neither libbsc itself nor tests using it
are actually linked against libcommon-cs

osmo-bsc currently negotiates the RTP stream directly with the
BTS and reports back the RTP IP/Port on the BTS. This works fine
for a single BTS, but for Handover the port/ip pointing to the
MSC side must not change, so an entity in between the BTSs and
the MSC is required.
Integrate the mgcp-client and use osmo-mgw to switch the RTP
streams.

This is the OsmoBSC project. Disabling the build of the BSC would be
somewhat odd, so let's remove the option.
Also, OsmoBSC depends on libosmo-sccp now, so we must unconditionally
depend on it. As a result, we can remove the --enable-nat option,
as this was only to avoid a mandatory libosmo-sccp requirement in
historical times.

Rewire build and includes to libosmo-legacy-mgcp.
Drop osmo-bsc_mgcp and related python tests, now found in osmo-mgw.git.
libosmo-legacy-mgcp is installed from osmo-mgw, hence add the dependency to
jenkins.sh (so far using the pre_release branch).

Remove libiu here, use the functions from libosmo-ranap instead, by applying
the ranap_ / RANAP_ prefix.
Corresponding change-id in osmo-iuh.git is I6a3f7ad15be03fb94689b4af6ccfa828c25f45c0
To be able to run the msc_vlr tests for RAN_UTRAN_IU without Iu client headers
available, add iu_dummy.h, containing mere function signatures that match
iu_dummy.c and a mostly empty struct ranap_ue_conn_ctx.
Make sure we can build with and without --enable-iu: include osmo-iuh headers
only with --enable-iu.

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.

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.

this small tool is used to enable layer 1 and 2 on a given isdn card.
the card can be used to retrieve clock signal from a network. layer 2
(PTP) is required to keep layer 1 without interruption. this tool works
on e1 and s0 cards. to use the clock signal with other cards,
interconnection with a clock-slave-card is required.

It will define -DVTY_CRYPT_PW= if crypt is found. If -lcrypt is
needed, $(LIB_CRYPT) will be -lcrypt.
Compiles on OS X and Linux and reenables crypt.

This will be used for generic registration and dispatching
of any kind of event. We will have different areas (like
with the debug interface) and each layer can define their
own struct for the event message... This is not tested yet
channel to another one (simple voice call switching)
* add a way more generic E1 input layer, abstracting out the misdn
low-level interface. This also adds infrastructure for multiple TRX
in one BTS, as well as multiple BTS on one E1 link
* add a E1 subchannel multiplexer for sending multiple 16kbit sub-channels
one one 64kBps E1 channel
* add TRAU IDLE frame generation
* terminate bsc_hack in case there is a E1 / mISDN init error
* introduce 'e1_config.c' file with static configuration of our
E1 setup (which TRX/BTS is configured for which TEI/SAPI/E1). This should
later become a config file rather than a compiled C file.
WARNING: all this compiles but is not tested yet. Expect fix-up committs over
the next hours or so
You can request to open a channel to a MS and the paging layer
will call you once the channel is allocated. Internally the CCCH
Load Indication will be handled and retry to page a terminal.
This might turn into a complete wire protocol with special
client software. For now it will be a simple client interface
that you can use with telnet to do certain things.
This is using flex to implement the parsing. Implementation
and more commands will follow.
One can use add_timer or schedule_timer to add a timer. After
the timeout time has been reached the callback will be called.
One can call add_time/schedule_timer and del_timer from within
the callback.
