smpp_try_deliver could fail with rc < 0. In such cases don't send the MS the rp
error sms rejected (cause 21). A rejected message should not be sent again. The
spec 04 11 recommends sending cause 41 Temporary failure in unknown cases.
Add also a log message and rate counter for such cases.

DEVELOPMENT HACK: Our current HLR does not support 3G authentication tokens. A
new HLR/VLR implementation is being developed. Until it is ready and actual
milenage authentication is properly supported, we are hardcoding a fixed Ki and
use 2G auth.

In gsm48_gmm_sendmsg(), redirect to iu_tx() for both cases of MM context
present or not.
In gsm48_rx_gmm_att_req(), compose an MM context marked as Iu for messages
coming in from a ue_conn_ctx (passed in msg->dst). Also make sure cid is
initialized to avoid introducing a compiler warning.
In gsm48_rx_gmm_ra_upd_req(), look up an Iu MM context based on the presence of
the ue_conn_ctx in msg->dst.
In sgsn-test, add libiu and libasn1c, libosmo-sigtran, libosmo-ranap, which are
now needed for an --enable-iu build.

As the NITB has an internal SIGABRT handler that prints a talloc report,
let's also print a stack backtrace at the same point.

For Iu connections, msg->dst will point to the ue_conn_ctx, and we need to make
sure to keep msg->dst intact when copying from/to msgb and from/to MM context.

Bit 4 is reserved in 3GPP TS 04.08 so exclude it from the type.
In 3GPP TS 24.008 it indicates if a follow-on request is pending by the
MS, but only in Iu mode. According to the spec it is not required to
react to that request with a follow-on proceed so this field can be
ignored for now.
See 3GPP TS 24.008 Ch. 4.4:
"Unless it has specific permission from the network (follow-on proceed)
the mobile station side should await the release of the RR connection
used for a MM specific procedure before a new MM specific procedure or
MM connection establishment is started."
as well as Ch. 4.4.4.6:
"If the network wishes to prolong the RR connection to allow the mobile
station to initiate MM connection establishment (for example if the
mobile station has indicated in the LOCATION UPDATING REQUEST that it
has a follow-on request pending) the network shall send "follow on
proceed" in the LOCATION UPDATING ACCEPT and start timer T3255."

With this commit the already existing XID mechanism has been
modified to suit the needs for the upcomming SNDCP-XID patches.
This commit should not break anything since it does not alter
the current behaviour (incoming XID is still just echoed, on
GMM-Reset a basic XID message is still echoed)

In rsl_lchan_mark_broken(), call rsl_lchan_set_state() so the state transition
gets logged in the debug log.
Remove logging for the broken channel at the callers, instead log the error
actually in rsl_lchan_mark_broken() itself, with the reason message passed by
the caller anyway. (Removes code dup and ensures it's always logged.)

Actually schedule an activation timer for the activation part of a dyn TS
switchover. It needs to be restarted because the channel release procedure in
the first part of a switchover actually removes the activation timer.
Change-Id: Ibf50d13ba10298464a8b07e34716763161438990
The dyn_ts_switchover_*() functions made the impression that they act on a
specific lchan of a timeslot. The assumption that we would remember to use e.g.
lchan[1] across a PDCH deactivation is brain damaged to begin with; and
factually we always use lchan[0] anyway (the only case for using lchan[1] would
be when switching to TCH/H, but the channel allocator will always return
lchan[0] for that).
Instead of the brain damaged lchan args, use a ts arg across all
dyn_ts_switchover_*() functions, with one exception: The
dyn_ts_switchover_complete() actually receives an RSL activation ack message on
a specific lchan and needs to evaluate its lchan type. This will always be
lchan[0] as it is now, but we should stick with the lchan the message was sent
for.
For PDCH, a check to use lchan[0] already existed, when composing the ACT
message in rsl_chan_activate_lchan_as_pdch(). Replace with an assertion.
Adjust all callers to pass ts instead of lchan.
In dyn_ts_switchover_start(), there was a dead code check that jumps to
switchover_complete() in case the pchan already matches. This never hits,
because we only call dyn_ts_switchover_start() when pchans mismatch. So avoid
guessing at passing lchan[0] to dyn_ts_switchover_complete() by not calling it
at all but logging an error instead.
In rsl_chan_activate_lchan(), we remember some values before going into
switchover from PDCH. Explicitly store them in lchan[0], because after a PDCH
release we have always and will activate no other than lchan[0].
In dyn_ts_switchover_continue(), move the check for any existing lchan->rqd_ref
further above, and more correctly check all lchans that were so far valid on
the TS, instead of just one.
This partly prepares for a subsequent commit to fix the act_timer use for dyn
TS: with the old lchan arg, we might schedule an activation timer on lchan[1]
but receive an ack on lchan[0] (for PDCH), leading to an act_timer expiry.

For TCH/F_TCH/H_PDCH dynamic timeslots, the ts->pchan does not lead to a
meaningful value from the subslots_per_pchan[] array. Use the ts_subslots()
function instead, which checks for dyn pchan.

Add web application exposing Control Interface over web. All of SET, GET
and TRAP are fully supported.
Notice: TRAP is converted into 'Server-sent events' according to RFC
6202, see also https://www.w3.org/TR/eventsource/ - this requires
corresponding client.
Due to use of special prefix modified version of python
eventsource-client is necessary ATM.
