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.

From a human admin viewpoint it doesn't make sense to count the messages sent:
When we use TMSIs, we first send a LU Accept with a new TMSI, and then expect
the MS to respond with a TMSI Realloc Complete message. When that fails to come
through, the LU actually ends in failure, even though a LU Accept was sent.
If a conn breaks/vanishes during LU, we cancel the LU without sending any reply
at all, so the failed LU would not be counted.
Instead, count Location Updating results, i.e. completion and failures.
(With the new VLR developments, LU counters need to be triggered in completely
different places, and this patch prepares for that by providing sensible
counters.)

we must instruct the L2TP daemon to instruct the SIU to change the Abis

The timer T3186, which is described in 3GPP TS 44.060, is using 3
bits of the si13 mac block. This requires special encoding. In the
case of T3186, the value is encoded by the formula: bits = t/500-1.
Our implementation uses the formula bits=t/500, which is incorrect.

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.

When the IMSI ACL is maintained via the VTY, users may enter IMSIs
without leading zeros. Especially in test environments, where
MCC=001 and MNC=01 is common, it is likely that someone enters the
corresponding IMSI (001010000000001) without the two zeros at the
beginning.
This patch fixes the problem by sanitizing the IMSI, eventually
missing zeros in the beginning will be automatically added.

Add via_ran to gsm_subscriber_connection to indicate whether a conn is coming
in via 2G/GERAN/A-Interface or 3G/UTRAN/Iu-Interface. Prepares for Iu, but
also for libvlr to decide between GSM or UMTS Auth.
Until actual Iu support is merged to master, this indicator will aid VLR unit
testing.
At some point we may also add RAN_GERAN_IU; it's not on the agenda yet, but to
clearly distinguish the names if we want to add it, explicitly name the ones we
have RAN_GERAN_A and RAN_UTRAN_IU.

Remove the fuzzer interface that was partially implemented in
gsm_04_08.c and silent_call.c is causing problems when an
SMS is sent during an active silent call. The reason for this
is that gsm0408_dispatch() in gsm_04_08.c would decide to
rout all uplink traffic to silent_call_rx() in silent_call.c.
silent_call_rx() is a stub function that discards the data.
This patch removes the fuzzer interface code by placing ifdefs
around it, so that it can be re-activated by experimentators.

Similar to a recent patch in osmo-python-tests for VTY based tests, but this is
for the Ctrl tests.
The TestCtrlBase tests gave a constant sleep(2) grace period for the process to
startup. This causes tests to take minutes for no reason at all.
Add code to TestCtrlBase to try and connect right away, retrying up to three
seconds in .1 second intervals. This flies through most tests without any
sleep() at all.

If a pdp context is created a xid request is sent right after
the pdp-context-ack message. The sending of the pdp-context-ack
and the xid message is triggered from the GGSN via the GTP
interface.
When the pdp-context-ack message is not received by the MS, it will
send the pdp-context-request again. A lost pdp-context-ack is resent
by the SGSN directly so that the mechanism described above does
not work for pdp-context-ack resents.
This commit adds code to trigger the sending of xid messages also
for resent pdp-context-ack messages.

On 'auth-policy remote', the SGSN requires GSUP server address and port. If it
was missing, the SGSN would print a VTY warning and run anyway. Make this error
more fatal: print an error (flattened a bit) to stderr and abort the program.
Move validation of the GSUP server data presence out of the VTY command itself
and into the config reading function. This way the GSUP server config can be
given anywhere, including below the auth-policy config (was required above).
Don't care about setting the auth-policy to remote with a telnet VTY, because
in that case the GSUP client won't be started anyway.

* parse extended UMTS RES
* on auth response, validate expected AKA with vector and received res/sres
* add Auth Failure message to receive resync AUTS token and
* send to HLR
* clear out-of-sync auth tuple
* enter new state for when we're waiting for HLR to resync and send new
tuples so that the next Auth Request will be handled

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.
