Move code to create an Insert Subscriber Data message into a common
function which can be shared by hlr.c and luop.c.
As a consequence, we always encode gsup.cn_domain in the corresponding
msgb and must adjust expected output of the 'gsup' test accordingly.

Encode an Insert Subscr Data with is_ps == true to trigger the encoding bug
described in OS#3231, i.e. show that it is fixed.
Move osmo_gsup_addr_send() to a separate .c file, so that it can be overridden
in the regression test to just dump the msgb instead.
I used this test to reproduce issue OS#3231, and now that it's here we might as
well keep it, and possibly expand on it in the future.

In osmo_gsup_configure_wildcard_apn(), do not compose APN into a local buffer
that becomes invalid as soon as the function exits. Instead, use a caller
provided buf.
Fixes OS#3231 crash:

This function relied on implementation details of the luop code.
Port what is necessary for an independent Insert Subscriber Data
Tx operation from the luop code into this function.
A next possible step would be to try to merge both of these
into a common implementation. This will be addressed in a
follow-up change as soon as this change is merged.
The TTCN3 test TC_vty_msisdn_isd is still passing (it currently
triggers the "circuit switched domain" case because it does not
advertise itself as an SGSN in the IPA unit name).

Use osmo_timer_setup() to set up the luop timer, instead of
settting the timer up manually.
Delete the timer before the luop is freed to prevent a potential
crash in case the timer is already armed and the function call
chain leading up to lu_op_free() does not cancel the timer.
Found while studying code to prepare work on issue OS#2785.
This change has been tested with 'make check' and TTCN3 HLR tests.

There will be more additions, _by_msisdn() and _by_id(), to serve the upcoming
VTY commands, to allow flexibly selecting subscribers as in the old OsmoNITB.

Add commands to enable/disable Packet Service for a given IMSI. Changes
are synced to DB and propagated at runtime to SGSN (in case of disable
command).

functions there to facilitate re-use in upcoming control interface.
