* add version string to gsm_bts
* add PCU version string to gsm_bts
* rename GSM_BTS_TYPE_OSMO_SYSMO -> GSM_BTS_OSMOBTS to avoid confusion
  between BTS model and variant
* add variant enum to gsm_bts_model using enum with variants for each

* show connected PCU version (if available) in vty via 'show bts'

This will come in handy when logging details regarding particular BTS
reported via OML, see:

Neels Hofmeyr 6dd0fc685b oap tests: fix after SQN scheme changes from libosmocore
In change-id Iadf43f21e0605e9e85f7e8026c40985f7ceff1a3, libosmocore changes
from incrementing SQN after tuple generation to incrementing SQN before tuple
generation. Thus we now need to pass desired_sqn - 1 to get the same tuples.

Neels Hofmeyr 6d804b1a7e add struct bsc_subscr, separating libbsc from gsm_subscriber
In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will
not make sense to use vlr_subscr in libbsc. Thus we need a dedicated BSC
subscriber: struct bsc_subscr.

Add rf_policy arg to bsc_grace_paging_request() because the bsc_subscr will no
longer have a backpointer to gsm_network (used to be via subscr->group).

Create a separate logging filter for the new BSC subscriber. The implementation
of adjusting the filter context is added in libbsc to not introduce
bsc_subscr_get/_put() dependencies to libcommon.

During Paging Response, fetch a bsc_subscr from the mobile identity, like we do
for the gsm_subscriber. It looks like a duplication now, but will make sense
for the VLR as well as for future MSC split patches.

Naming: it was requested to not name the new struct bsc_sub, because 'sub' is
too ambiguous. At the same time it would be fine to have 'bsc_sub_' as function
prefix. Instead of struct bsc_subscriber and bsc_sub_ prefix, I decided to
match both up as struct bsc_subscr and bsc_subscr_ function prefix. It's fast
to type, relatively short, unambiguous, and the naming is consistent.

Add bsc_subscr unit test.

Neels Hofmeyr a42855f09f cosmetic: rename osmo_msc_data.h to bsc_msc_data.h
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.

Neels Hofmeyr 89a8e722ed logging fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*

Neels Hofmeyr f13b3c968f logging: use central filter and ctx consts from libosmocore
The LCHAN and BTS filter contexts are actually never used, so drop them until
someone adds them properly.

For now use only LOGGING_{FILTER,CTX}_VLR_SUBSCR. Some of these will change to
_BSC_SUBSCR once struct bsc_subscriber is introduced, and later on, struct
gsm_subscriber will be replaced by vlr_subscriber so that the names will match.

messages from experr.

Todo: we're using a "Library" logging category, which is not really what the

given a logging category like DVLR or DGPRS in its initialization API.

Add ts_is_tch() in gsm_data_shared.h/.c and use it to replace a switch on the

This patch is not due to an actual observed failure. A general grep for switch

this patch is not actually tested with real equipment.

Neels Hofmeyr c3f72f63af dyn TS: fix: ts_subslots() for TCH/F_PDCH in PDCH mode
In gsm_data_shared.c, add ts_pchan() to determine actual pchan type for dynamic
and non-dynamic TS.

Use in ts_subslots() to fix the value returned for TCH/F_PDCH in PDCH mode.
Adjust the assertion in channel_test.c accordingly.

Drop GSM_PCHAN_TCH_F_PDCH, which is now handled in ts_pchan().
Explicitly add GSM_PCHAN_PDCH as zero in subslots_per_pchan[] (cosmetic).
Adjust the comment in subslots_per_pchan[].

The fix for the number of subslots affects only one caller: bts_chan_load() in
chan_alloc.c. Before this, it would always include a TCH/F_PDCH in the
load_counter->total, now it is skipped when in PDCH mode. Whether this is the
way bts_chan_load() should handle dynamic TS is a separate discussion, so far
I'm only making sure that the two dyn TS kinds act in the same way:
TCH/F_TCH/H_PDCH is only counted when in TCH mode, and TCH/F_PDCH should match.

Openbsc and osmo-bts each define their own DRSL log constant, so add an int *rc
return code argument and keep the logging part in abis_rsl.c's thin lchan_lookup()
wrapper. Incidentally, this also removes code dup for logging.

To avoid duplicate symbols, the rsl_lchan_lookup() implementation needs to be

this.

* add vty command "authorized-regexp" for setting arbitrary POSIX
  regular expression
* add basic vty test
* add optional "regexp" argument to subscriber-create-on-demand vty
  command

With those in place we can now set the regexp against which MS's IMSI
will be matched.

If IMSI match the regexp than MS is allowed to access the network. If
subscriber is already marked as authorized in HLR than it'll be allowed
regardless of IMSI matching.

The same way we can decide whether to create subscribers on-demand
basesd on IMSI regexp match. Similar to authorization this restriction
can be overridden by manually creating subscriber via vty, ctrl
interface or directly in HLR.

openbsc.

Harald Welte c696cc28d8 gsm_data_shared: compute/sprintf the lchan name only once
We now store the pre-printed lchan name in lchan->name to avoid having

particularly as most of those debug statements are going to be inactive
most of the time.
