Rename current subscr_con_allocate() and subscr_con_free to bsc_*,
and add two separate msc_subscr_con_allocate() and _free().
The msc_subscr_con_free() ignores all lchan members.
In libbsc use bsc_*, in libmsc use msc_*.

Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS
structures will be available on the MSC level. To simplify, drop the ability to
manage several time zones in a core network and place the time zone config on
the network VTY level, i.e. in gsm_network. If we are going to re-add fine
grained time zone settings, it should probably be tied to the LAC.
Adjust time zone VTY config code (to be moved to libxsc in subsequent commit).
Adjust time zone Ctrl Interface code.

Implement connection_for_subscr() from a completely different angle: instead of
looking up lchans in bts structs, look up the subscriber in the global list of
gsm_subscriber_connection. static lchan_find() is thus obsoleted.
All callers of connection_for_subscr() live in libmsc, so move to libmsc.
The move and edit are done in a single commit since the old and new
implementation have nothing in common.
Future: osmo-cscn will use this, without bts being present.
Remove implementation of connection_for_subscr() from channel_test.c -- it is
possible that the abort() in there was intended for a regression test, but
actually it seems the implementation was merely added for linking reasons, and
the abort() added to guard against the NULL return value: no comment nor the
commit log indicate that the abort() is test critical; the addition was the
only change in channel_test.c for that commit; at the same time a
connection_for_subscr() call was added in libmsc.

Keep only BSC specific bits of the 'network' VTY node in bsc_vty.c, move more
general VTY commands to xsc_vty.c.
Add arg to xsc_vty_init() to pass a config_write_net() function. Pass a libbsc
specific config_write_net() function.
Future: upcoming omso-cscn will re-use the VTY bits moved to libxsc and pass a
different config_write_net() function.

Move gsmnet_from_vty() and the bsc_gsmnet global to xsc_vty.c.
Rename bsc_gsmnet to vty_global_gsm_network and make it static to xsc_vty.c, to

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.

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.

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
that hints at the proper pchan type to use instead: TCH/F_TCH/H_PDCH

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.

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.

This reverts commit 308cb0719dca3ba8eed1eff2a2124d44f34d9a28.
Problems in this commit:
openbsc/src/libbsc/chan_alloc.c:523: case GSM_PCHAN_TCH_F_PDCH:
This is actually wrong, GSM_PCHAN_TCH_F_PDCH use ts->flags, not ts->dyn below
(due to historical reasons and could be unified).
560: if (only_count_tch && !chan_is_tch(ts))
This has exactly one effect: it excludes GSM_PCHAN_TCH_F_PDCH when in PDCH
mode, because for all other PDCH (plain PDCH and TCH/F_TCH/H_PDCH in PDCH mode)
below ts_subslots() returns 0 and skips the for() loop. I consider this a bug
in TCH/F_PDCH, to be fixed in an upcoming commit.
I don't see why we need the only_count_tch argument, because this should
normally only count TCH, weren't it for the TCH/F_PDCH bug.
If dyn TS should be counted differently, we should do this in a different way.
