For unconnected BTS, the channel load would report a "bogus channel load
sample" every second (on RLL debug). Instead, skip unusable BTS.
This follows up on commit 6cee893a0f2c4e53155a2631aff12a5f615b973d /

'Make "waiting indicator" of IMMEDIATE ASSIGN REJECT dynamic.'
Port of omo-bsc commit f802f7fd7aec1d91084231a80bbce6f2ed7bd299
Change-Id: Icd50d101244641a6ffdde17e60d7a89719225c65
The IMMEDIATE ASSIGN REJECT message contains a wait indicator which
tells an MS requesting a channel to wait for a specified amount of
time before trying to request a channel again, i.e. the wait indicator
controls the T3122 timeout value in the MS.
Previously, the wait indicator was fixed to 10 seconds.
This is not sufficient if there are a lot of MS requesting channels
because the MS will retry too soon. Instead of using a fixed value,
maintain a dynamic wait indicator value based on average channel load.
The load (used vs. available channels on a BTS) is sampled once per
second, and once 8 samples have been collected we update a BTS-specific
T3122 wait indicator based on the measured load.
While the wait indicator could go up to 255 seconds, this initial
implementation keeps it in the range from 10 to 128 seconds.
Further experimentation and testing will show whether higher wait
indicator values are desirable, if the sampling rate needs to change,
or if the function mapping the load measurement to a wait indicator
value should change (currently we map the load average linearly into
the range [10, 128] inclusive).

Fixes a regression in the code generating SI5* and SI6 on SACCH,
where the L2 pseudo-length is not part of the 'struct' definition
we have in gsm_04_08.h and hence has to be encoded manually into
the first byte of the SI buffer.
We were doing this correctly until April 2017, when the following
patch was merged:
> commit 6f0e50c833
> Author: Max <msuraev@sysmocom.de>
> Date: Wed Apr 12 15:30:54 2017 +0200
>
> Prepare for extended SI2quater support
This patch cacidentially overwrote the l2_plen that was just enoded,
as the 'struct' was no longer pointing to 'output' (si_buf+1), but
now directly to the start of the si_buf.
NOTE: The Wireshark RSL dissector (and more recently also LAPDm)
contain a similar bug, so the SACCH will not be decoded correctly
after applying this patch. Nevertheless, it's correct.

After recent libosmocore commit "implement support for 3-digit MNC with leading
zeros" c4fce1425e19d604c199c895e227dc2519110456
Id2240f7f518494c9df6c8bda52c0d5092f90f221, struct gprs_ra_id has a new member,
namely mnc_3_digits. In gprs_ra_id_by_bts(), this new member is now not
initialized and may end up having an arbitrary value, which then may amount to
mnc_3_digits == true. Hence the resulting BCD representation of the MCC-MNC may
inadvertently and randomly indicate a leading zero on the MNC.
Use a struct assignment so that all members are guaranteed to be set, and so
that mnc_3_digits will be zero in all cases.
Since above libosmocore commit, nanobts_omlattr_test fails "randomly", fixed by
this patch.

In state prior to this patch, "3G Early Classmark Sending Restriction"
bit in SI3 rest octets was always set to H, which is a sane default as
the policy to send the information is then controlled by "Early

However, it seems Quortus SoftCore can have some issues decoding the
option, so let's add a vty cmd to be able to disable it for those

In osmo-bsc-sccplite we so far didn't implement the inbound RESET
procedure. We instead ignored any RESET message from the MSC. This
commit adds support for RESET: We will destrpy any SCCP connections
and acknowledge the RESET to the MSC.
As osmo-msc is requiring the BSC to handle an inbound RESET procedure,
this commit allows osmo-msc to properly initialize the A interface
towards osmo-bsc-sccplite via a translating/routing osmo-stp. While
we don't anticipate any new deployments of osmo-bsc-sccplite, making
it interoperate with osmo-msc enables us to do more testing of
osmo-bsc-sccplite.

Possible scenario in which this crash can appear:
1- gsm0808_assign_req() calls handle_new_assignment() which sends an CHAN
ACTIVATE msg and arms T10 timer.
2- ACTIVATE ACK is received (handle_chan_ack), which calls
gsm48_send_rr_ass_cmd() which sends an ASSIGNMENT CMD, and doesn't
disable/modify T10 timer.
3- T10 timeout is triggered (assignment_t10_timeout()), which sets
conn->secondary_lchan = NULL
4- Immediately after, the ASSIGNMENT FAILURE message (which might have been
already queued) is processed in handle_ass_fail, and then the crash occurs.
This race condition is not an issue for handle_ass_compl() path because there's
this check there which would trigger most probably if secondary_lchan is NULL:
"if (conn->secondary_lchan != msg->lchan)"

d64b6aed235f6e4d84a2cb8e84b32c3179260254, we no longer do this implicit-exit in

*) the nitb node lacked the default command set (including 'end' and 'exit'),
so it was impossible to leave the nitb node. This hit in
testSubscriberCreateDelete. Add vty_install_default(NITB_NODE).
*) in testPingPongConfiguration, the intention is to enter the /msc 0 node.
Drop prior entry of the 'network' node, which looks like an oversight. So
far the 'msc 0' caused an implicit 'exit' and thus worked, now fails.
*) Two instances following comments "# Check searching for outer node's
commands", which look like they are intended to check for this implicit-exit
behavior. This is obsolete, drop those parts of the tests.

Handover attempt for power budget case should be performed every N SACCH frames,

First measurement report with mr->nr = 0 was used for the first handover attempt
in this case, which is not correct, because first usable report should have
mr->nr = net->handover.pwr_interval-1.
Moreover using the first measurement report with mr->nr = 0 for handover attempt
could lead to unnecessary handover, because usually av_rxlev for first measurement report
from MS is worse than for following reports.
