Comparing an array to null is not useful, since the test will
always evaluate as true (NO_EFFECT).

Move the translation from osmo_sockaddr_to_str_and_uint into
bssmap_handle_ass_req_tp_rtp_addr, which will be used by
bssmap_handle_ass_req_ct_data in a future patch too.

tall_ctr_ctx is not defined or used in osmo-bsc and apparently was only
exported by accident from libosmocore. It's not exported anymore since
libosmocore.map was introduced in I13169c00a59fb59513dfc598de5a71d094492422.

Let's typecast any unsigned arguments to signed int to work around.

T23042 was a placeholder for timers to be filled in later. Replace it
with timers that can be configured via VTY.
Previous timeout for the states was 5s, from using the default of 5 for
undefined timers.
* ASSIGNMENT_ST_WAIT_MGW_ENDPOINT_TO_MSC and
HO_ST_WAIT_MGW_ENDPOINT_TO_MSC:
* Runs gscon_connect_mgw_to_msc() on enter, which waits for one MGCP
CRCX or MDCX response (or changes state immediately)
* Use existing X9 ("Timeout for availability of MGW endpoint"), 5s,
which is already being used by lchan_rtp_fsm for a similar purpose
* HO_ST_WAIT_RR_HO_DETECT:
* Handover initiation as described in 3GPP TS 04.08 § 3.4.4.1:
"The network initiates the handover procedure by sending a HANDOVER
COMMAND message to the mobile station on the main DCCH. It then
starts timer T3103."
* Use existing but unused timer T3103 ("Handover"), 5s
* HO_ST_WAIT_RR_HO_COMPLETE:
* Handover completion as described in 3GPP TS 04.08 § 3.4.4.3:
"When receiving the HANDOVER COMPLETE message, the network stops
timer T3103 and releases the old channels."
* Continue using T3103 with keep_timer = true

Remove placeholder timer T23042. This handover fsm state waits for both
RSL/RR and RTP/MGW to be complete. I've added TTCN-3 tests to ensure
that both cases are covered by existing timer T3101 in lchan fsm state
LCHAN_ST_WAIT_RLL_RTP_ESTABLISH, which on timeout lets the handover
fail.

In classic E1 based GSM networks the audio is usually transfered through
16bkps I.460 subslots while 4 16kbps subslots are multiplexed into one
E1 timeslot. However, there may be setups where still 16kbps subslots
are used, but with 1 instead of 4 channels per timeslot. In those cases
the bit offset is 0, while the rate is still 16kbps.

The BSC has all information about the E1 line configuration of each
timeslot/channel. The PCU is responsible for opening and managing the
CCU connection. To enable the CCU to do that, we have to transfer the E1
connection information (which TS, SS, rate) to the PCU.

A new VTY node was added in commit [1], but bsc_vty_go_parent() was
not updated. Because of that, commands following the MGW node may
crash osmo-bsc. In the example below:
network
network country code 901
mobile network code 70
...
mgw 0
remote-ip 127.0.0.1
local-ip 127.0.0.1
periodic location update 30
the 'periodic location update 30' will trigger a segfault:

The Ericsson RBS is a BTS that natively works with dynamic timeslots.
This colides with the current understanding of static PDCH channels
because the BTSs we support so far get thier static PDCH information on
startup and then handle everything related internally. The BSC does not
actively manage the channel in those cases. In the case of Ericsson we
have to activate the PDCH via RSL like any other channel and the timeslot
FSM has to manage it. Lets not add work arouds for this, lets just print
and error message and use the BTS in the dynamic scheme as intended by
the manufacturer.
