mgcp: hack RAB success from nano3G: patch first RTP payload
The ip.access nano3G needs the first RTP payload's first two bytes to read hex
'e400', or it will reject the RAB assignment. Add flag
patched_first_rtp_payload to mgcp_rtp_state to detect the first RTP payload on
a stream, and overwrite its first bytes with e400. This should probably be
configurable, but seems to not harm other femto cells (as long as we patch only
the first RTP payload in each stream). Only do this when sending to the BTS
side.

Since the VLR development marks a move away from the 'openbsc' name, now is a
good opportunity to also change the default config file name to the more
accurate and obvious 'osmo-nitb.cfg'.

libvlr now delegates subscriber management to osmo-hlr, so the database no
longer represents a HLR. It basically only stores SMS, so reflect that fact in
the default database name.

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 development collapsed in one patch. The original
history may still be available as branch neels/vlr_orig.
TODO: This commit may be split in several smaller changes before merging to
master.
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.

This option allows to enable or disable TCH/F allocation on the
TCH/F_TCH/H_PDCH timeslots. Until now, source code modification
was required to enable this feature.

With the OsmoMSC program coming up, the name osmo_msc_data becomes even
more confusing than it already is. Clearly indicate it as libbsc's data of
a remote MSC by prefixing with bsc_.
Also, the Osmocom community has in the meantime agreed to have the osmo_
prefix only in libosmocore, to avoid naming conflicts in case things are
moved there. So while renaming anyway, also drop the osmo_ prefix.

Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores
parameters to log_vty_command_* functions. Hence parameter of
logging_vty_add_cmds() is ignored too. As we depend on much later
libosmocore version anyway, we can simplify code somewhat by removing
parameters which will be ignored anyway.

Call vty_init() before handle_options() to make sure the host.app_info is
populated before --version potentially tries to print it.
The segfault was introduced by 2c05f75bbf3d9a69eee1fe78eb5552acf1d7671d in a
recent MSC-split merge.

Now that bsc_network_alloc() is separate, move it to before the VTY init (a
subsequent patch will pass the gsm_network instance as a parameter to
vty_init()).
bsc_hack.c: drop the comment that says about the VTY init: "This needs to
precede handle_options()" -- it is not accurate. Actually move the
handle_options() above both vty_init() and the bsc_network_alloc() calls, to be
able to decide which mncc callback to pass to bsc_network_alloc. It would make
sense to set this later on, but that would require further refactoring of the
bsc_network_init() and gsm_network_init() signatures, so not in this patch.

For patch clarity, keep some code dup to be removed in a subsequent patch. In
the same sense don't change the fact that mncc_sock_init()'s return value is
ignored.
The global gsm_network instance 'bsc_gsmnet' is basically only used by the VTY,
and a future patch will "hide" that global in a vty .c file. In a nutshell, I
want to
- first allocate a gsm_network,
- then initialize the VTY passing the gsm_network pointer,
- and then read the config file using the initialized VTY.
So far, bsc_bootstrap_network() allocates the gsm_network and reads the config
file right away, which only works by sharing the extern bsc_gsmnet pointer,
which I would like to uncouple.

Add an explicit gsm_network pointer instead of using the bsc_gsmnet global.
This allows passing a gsm_network struct from the main() scope, which helps to
decouple libmsc from libbsc.

Decouple the talloc context allocations from global tall_bsc_ctx pointer.
It appears that talloc_ctx_init() was intended for general use, since it is
located in libcommon. It is currently used only by osmo-nitb; but the upcoming
osmo-cscn will use it as well.
Instead of defining in osmo-nitb main file, add definition in gsm_data.h.

To avoid two phones picking mismatching TCH pchans, never pick TCH/F on dynamic
TS in osmo-nitb.
Add gsm_network flag dyn_ts_allow_tch_f, set to true by default in
gsm_network_init().
Set this flag to false in osmo-nitb's main().
See http://osmocom.org/issues/1778
Reasoning about ways to solve this:
* a compile time switch doesn't work because libbsc is first compiled and then
linked to both osmo-nitb and osmo-bsc.
* we could test net->bsc_api == msc_bsc_api(), but I have the so-called MSC
split waiting on branch sysmocom/cscn, which will result in msc_bsc_api() not
being linked in the osmo-bsc binary.
* have a function am_i_nitb() with different implementations in osmo-nitb and
osmo-bsc, but then we'd need to add implementations to all tests and other
binaries linking lchan_alloc().
* have a flag in struct bsc_api, but so far there are only function pointers
there.
Having a "global" flag in gsm_network allows to add a VTY command in case we
decide to keep this feature (#1781), has no linking implications and is nicely
explicit.
Tested that osmo-bsc still picks TCH/F on dyn TS indirectly, since I have no
standalone MSC available: when compiling osmo-nitb with the line that sets
dyn_ts_allow_tch_f = false commented out, TCH/F is picked as described in
OS#1778; and by printf-verifying that dyn_ts_allow_tch_f == true in osmo-bsc
main(), only osmo-nitb should have TCH/F disabled.

Make the SMPP bind address configurable (used to be harcoded as "0.0.0.0").
Add VTY command
smpp
local-tcp A.B.C.D <1-65535>
while keeping the old command 'local-tcp-port <1-65535>'. Both the old and the
new command immediately change the SMPP listening address and port.
Add a LOGL_NOTICE log when the SMPP listening address and/or port change.
However, to be useful, this patch has to go somewhat further: refactor the
initialization procedure, because it was impossible to run the VTY commands
without an already established connection.
The SMPP initialization procedure was weird. It would first open a connection
on the default port, and a subsequent VTY port reconfiguration while reading
the config file would try to re-establish a connection on a different port. If
that failed, smpp would switch back to the default port instead of failing the
program launch as the user would expect. If anything else ran on port 2775,
SMPP would thus refuse to launch despite the config file having a different
port: the first bind would always happen on 0.0.0.0:2775. Change that.
In the VTY commands, merely store address and port if no fd is established yet.
Introduce several SMPP initialization stages:
* allocate struct and initialize pointers,
* then read config file without immediately starting to listen,
* and once the main program is ready, start listening.
After that, the VTY command behaves as before: try to re-establish the old
connection if the newly supplied address and port don't work out. I'm not
actually sure why this switch-back behavior is needed, but fair enough.
In detail, replace the function
smpp_smsc_init()
with the various steps
smpp_smsc_alloc_init() -- prepare struct for VTY commands
smpp_smsc_conf() -- set addr an port only, for reading the config file
smpp_smsc_start() -- establish a first connection, for main()
smpp_smsc_restart() -- switch running connection, for telnet VTY
smpp_smsc_stop() -- tear down connection, used by _start() twice
And replace
smpp_openbsc_init()
smpp_openbsc_set_net()
with
smpp_openbsc_alloc_init()
smpp_openbsc_start()
I'd have picked function names like "_bind"/"_unbind", but in the SMPP protocol
there is also a bind/unbind process, so instead I chose the names "_start",
"_restart" and "_stop".
The smsc struct used to be talloc'd outside of smpp_smsc_init(). Since the smsc
code internally uses talloc anyway and employs the smsc struct as talloc
context, I decided to enforce talloc allocation within smpp_smsc_alloc_init().
Be stricter about osmo_signal_register_handler() return codes.

Add ctrl_vty_init() calls and feed the ctrl_vty_get_bind_addr() return value to
ctrl_interface_setup() in the following programs:
osmo-bsc
osmo-bsc_nat
osmo-nitb
osmo-sgsn
For osmo-sgsn, move the control interface setup invocation below the config
parsing, so that the ctrl_vty_get_bind_addr() can return the configured
address.

Abort upon unknown options and missing option arguments. This came to my
attention while rewiring the -m and -M options: passing -M without argument
would launch nitb with wrong configuration. So, rather exit immediately.
If there are legacy options that should be ignored, they deserve an own 'case:'
in the option switch. There are none that I'm aware of though.

Strictly speaking, the unix domain socket location is not a name but a path.
The MNCC socket is called path, so it is confusing to call the ctrl socket
a 'name'.

The old -m option without argument is still available and marked deprecated,
to not make users' lives more difficult than necessary.

Currently every subcriber object directly refers to the gsm_network
which contains a flag shared by every related subscriber
(keep_subscr). This adds a dependency on gsm_network even if only the
function defined in gsm_subscriber_base.c are used.
This patch adds a new struct gsm_subscriber_group which contains the
keep_subscr flag and a back reference to the network object. The
latter is not dereferenced in gsm_subscriber_base.c, so it can safely
be set to NULL when only that part of the gsm_subscriber API is being
used. It also changes that API to use gsm_subscriber_group instead of
gsm_network parameters.
Since there are some places where a pointer to the gsm_network is
needed but where only a gsm_subscriber is available, a 'net' back
pointer is added to the group struct, too. Nevertheless subscr group
and network could be separated completely, but this is not the topic
of this commit.

Make sure that bsc_gsmnet->bsc_data->rf_ctrl is initialized for

for the NITB.

As bsc_gsmnet is NULL at the time we call smpp_openbsc_init(),
we later run into segfaults with subscribers that don't have a
subscr->net set.
However, we cannot delay smpp_openbsc_init() until after
bsc_bootstrap_network(), as we then fail to parse the SMPP specific
VTY/config file options...

This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.
