Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and
gsm0480_send_releaseComplete() functions, since there will be distinct
subscriber connection structs.
The current functions live in libmsc, so add the same in libbsc in new file
gsm_04_80_utils.c.
To avoid too much code dup, move the message generation part of
gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() to new functions
gsm0480_gen_ussdNotify() and gsm0480_gen_releaseComplete(), placed in libxsc.

Used by libbsc, libmsc as well as osmo-bsc and osmo-bsc_nat.
Moving gsm48_create* to libxsc affects linking of osmo-bsc_nat, resulting in
undefined references to gsm48_extract_mi() and gsm48_paging_extract_mi(); fix
that by placing libfilter.a left of libbsc.a upon linker invocation.

Reincarnate gsm_network_init() as the parts not specific to libbsc.
Move from bsc_network_init() those bits that are not BSC specific (and useful
for upcoming osmo-cscn).
Add libxsc to all linkages that use gsm_network_init().
Note: the only requirement to allow linking gsm_network_init() without libbsc
is to keep the call to gsm_net_update_ctype() out of libxsc. The other items
are kept out of libxsc because it makes sense semantically. But the separation
is not strong in that the BSC specific data members are of course still
omnipresent in struct gsm_network. If bsc_network_init() is not called, these
are not initialized properly -- for now no users of uninitialized members
exist.
So this is just a first step towards a sensible split of the BSC and MSC
gsm_network structs. The long term aim should be to have entirely separate
structs with some common general items.

bsc_network_init() is more fit to live in a BSC specific header.

The gsm_network_init() function initializes a whole lot of BSC specific stuff.
Aiming to move some of it to libxsc, first rename it to bsc_network_init().
This will retain the BSC specific stuff when the move is done.
Adjust all callers.
Future: osmo-cscn will call the more generic part and not the BSC specific
part.

Put mncc_recv_cb_t in xsc.h to avoid header include complications: if placing
right above struct gsm_network, one must include gsm_data.h to use
mncc_recv_cb_t as function parameter in a header, which will include
gsm_data_shared.h, which will include xsc.h (future knowledge). Since I will
need to use mncc_recv_cb_t in xsc.h, including gsm_data.h from there would
introduce an #include loop. Avoid that and define mncc_recv_cb_t in xsc.h to
begin with.

For TCH/F_PDCH, return an invalid chan comb (0) and print an error message

When OM2K sets up the timeslots with the BTS, the dynamic channel state
is not yet resolved to any particular pchan type. Instead of using the
dyn state, always advertise dynamic timeslots as pchan2comb(TCH/F).
In the past, the Ericsson dynamic timeslots were handled as pchan type
TCH/F_PDCH. This is a mistake, as this pchan type is intended for
the ip.access dynamic PDCH way of dynamic channels. In any case, in the
initial state of this pchan type, the timeslot was initialized as
pchan2comb(TCH/F) because the ts->flags do not reflect an active PDCH
yet. In short, this patch does not change the behavior of TCH/F_PDCH
timeslots, only clarifies it.
It would in fact make sense to disallow use of TCH/F_PDCH for OM2K,
but that should probably be a separate patch.
The proper pchan to use for Ericsson dynamic timeslots is
TCH/F_TCH/H_PDCH. These do not use ts->flags, but ts->dyn.* as state,
which first reflects pchan_want == pchan_is == GSM_PCHAN_NONE. Hence
the timeslot was initialized by OM2K as pchan type zero, which is
unknown / invalid. So, instead of using pchan_is, which is not yet
reflecting anything meaningful, always initialize as TCH/F chan comb,
as Ericsson hardware apparently expects it.

In case of the sysmoBTS and receiving a channel activation ack on a channel
that was marked as broken, release it again.
Use a normal release without SACCH deactivation and release the rqd_ta data.
Also add a local variable 'ts' to shorten some lines.
The typical situation where this would occur is with high latency between BTS
and BSC (or NITB). If a channel activation ack does not arrive in time, a
channel is marked broken, and never recovers after that. This patch will
release the channel again, which will remove the BROKEN_UNUSABLE state and
makes lchan available again. Reported by Rhizomatica.
However, in case of packet loss, i.e. when the channel activation ack never
arrives at the BSC, this patch does not provide a resolution of the
BROKEN_UNUSABLE state.
On dynamic timeslots: clearing the dyn ts state could possibly happen in
lchan_free() instead of in rsl_rx_chan_act_ack(). That's to be done in a
separate patch, if at all.

The GTP protocol specification requires us to include the MSISDN IE in
all non-secondary PDP context activations. However, when no real HLR is
used (e.g. via GSUP), we do not have the MSISDN information available
and so far simply sent a zero-length MSISDN IE in GTP. The latter is a
violation of the spec.
So to resolve this, we now send a 15-digit all-zero dummy MSISDN IE, as
described in TS 23.003.

Our existing OM2000 code for initializing all Managed Objects of a BTS
at startup was never complete. Rather than trying to fix the old-style
code, introudce a hierarchy of osmo_fsm's reflecting the full protocol
hand-shake and sequence of bringing up the individual MO's.
If this works out well, it mihgt make sense to convert the TS 12.21 OML
code for other BTS models, too.

Extend both 'show lchan <bts> <trx> <lchan>' and 'show lchan summary' to
include information on dynamic timeslots.
Have one common function that prints " as foo" or " switching foo -> bar" to
the vty, use it in lchan_dump_full_vty() and lchan_dump_short_vty().
In lchan_dump_short_vty(), split the vty_out call in two in order to interleave
the dyn ts info right after the pchan.
The summary hence looks e.g. like this for osmocom style dyn ts:
BTS 0, TRX 0, Timeslot 5 TCH/F_TCH/H_PDCH as PDCH, Lchan 0, Type NONE, State ACTIVE - L1 MS Power: 0 dBm RXL-FULL-dl: -110 dBm RXL-FULL-ul: -110 dBm
or
BTS 0, TRX 0, Timeslot 4 TCH/F_TCH/H_PDCH switching NONE -> PDCH, Lchan 0, Type NONE, State BROKEN UNUSABLE - L1 MS Power: 0 dBm RXL-FULL-dl: -110 dBm RXL-FULL-ul: -110 dBm

count_codecs() is called on every chan act ack, also for channels other than
TCH/F and TCH/H. So this logging happens a lot during normal operation but adds
no real information.
Also, RSL would be the wrong logging category for this -- RSL is about the RSL
communications, not whether our internal code tries to count lchan codecs for
the wrong channel types.

As per TS 23.014, a GSM MSC must implement mobile-originated DTMF
generation. We gate the DTMF signalling messages to MNCC, and expect
the external MNCC handler to deal with it. However, the internal MNCC
handler simply ignored such singalling messages, rather than rejecting
DTMF altogether.
It turns out failure to respond to START DTMF will cause some phones to
behave in interesting ways, particularly with modem
firmware v6.01.00, see https://osmocom.org/issues/1817). In this case
the phone is not able to release the call as the pending response to the
START DTMF is probably keping a reference or lock of some sort.

GSM 04.18, which is the successor of GSM 04.08, describes
additional RR 3g specific message types. This commit adds
log output for those messages. The behaviour is not changed
all affected message types are still forwared to the MSC
as they were before.
See also 3GPP TS 04.18, section 10.4, table 10.4.1

the OML attribute tables are hardcoded. To set variable parameters,
the hardcoded data structure (tlv) is patched on byte level during

- Replace hardcoded OML attribute tables with dynamically

- Add unit tests to check if the OML attribute tables are
generated correctly
- Put OML attribute table generator code in a separate file:
