When an MS indicates that it is ready to receive MT SMS, the MSC will
send us a READY-FOR-SM.req message. Handle it by sending copies of
the same message to all connected SMSCs and returning OK result
to the MS that indicates its ready status.

When an SMSC tries to deliver an SM to a subscriber, it will send us
an MT-forwardSM.req GSUP message. We look up the subscriber by IMSI
and see if they are attached to a VLR. If the subscriber is attached,
we forward the message to the MSC/VLR, otherwise return an error
to the SMSC.

MO-forwardSM.req messages are now forwarded to a connected SMSC
based on the SMSC address (SM-RP-DA) in the MO SM and the vty-defined
mapping from SMSC numeric addresses to IPA names.

At the user-visible level (advanced settings menus on phones,
GSM 07.05 AT commands, SIM programming) each SMSC is identified
by a numeric address that looks like a phone number, originally
meant to be a Global Title. OsmoMSC passes these SMSC addresses
through as-is to MO-forwardSM.req GSUP message - however, SMSCs
that connect to OsmoHLR via GSUP identify themselves by their
IPA names instead. Hence we need a mapping mechanism in OsmoHLR
config.
To accommodate different styles of network design ranging from
strict recreation of classic GSM architecture to guest roaming
arrangements, a two-level configuration is implemented, modeled
after EUSE/USSD configuration: first one defines which SMSCs exist
as entities, identified only by their IPA names, and then one
defines which numeric SMSC address (in SM-RP-DA) should go to which
configured SMSC, with the additional possibility of a default route.

Previously the HLR sent in the Insert Subscriber Data call only the
wildcard APN as a single entry.
This violates the spec because the first entry (with the lowest context_id) is
always the default APN, but it is forbidden to have a wildcard APN as default apn.
Introduce a default template/profile which can contain multiple APNs.
This profile is always sent out to the SGSN/MME as part of Insert-Subscriber-Data.
In the future a subscriber might have a profile template name written into the
database which will resolve to a "pdp-profile premium" in the configuration.
To be backward compatible, if the pdp-profile default section is missing,
the HLR will send out only a wildcard APN.
Config example:
hlr
ps
pdp-profile default
profile 1
apn internet
profile 2
apn *
Changes to the apn list will be only handed out to subscribers
when the subscriber do a location update.

Other UMTS AKA algorithms than MILENAGE (notably TUAK) support K sizes
of up to 256bit, or mandate a OP/OPc size of 256 bit.
Let's extend our database schema to accommodate such larger sizes.

The usual Data Coding Scheme value in the mobile-originated USSD
request (processUnstructuredSS-Request) is 0x0f, which means:
0000 .... = Coding Group: Coding Group 0 (Language using the GSM 7 bit default alphabet)
.... 1111 = Language: unspecified
However some modems are known to use a different default value, if
not specified explicitly (AT+CUSD has optional DCS parameter):
0000 .... = Coding Group: Coding Group 0 (Language using the GSM 7 bit default alphabet)
.... 0000 = Language: German (0)
In function rx_proc_ss_req(), we should not be using req.ussd_text,
because this field has been deprecated and may contain unexpected
data. For example, in the abovementioned case it would contain the
7 bit encoded ussd-String 'aa510c061b01'O and osmo-hlr would indeed
fail to find a matching route for a non-ASCII string.
Instead of relaying on gsm0480_parse_facility_ie(), let's check the
Data Coding Scheme value and decode the request string ourselves.
Expect the Coding Group 0, but be more tolerant to the indicated
language: print a warning and treat it as '1111'B (unspecified).

This is primarily to make the linter happy, which spews "static const
char * array should probably be static const char * const" errors in
gerrit when adding similar new code to this existing file. So let's
first convert the old code and then add new code that makes the linter
happy. I guess it does have a point, as both the individual string
pointers as well as the array of the pointers are constant.

libosmogsm has recently introdcued a 'struct osmo_sub_auth_data2' as
successor to 'struct osmo_sub_auth_data', together with updated
osmo_auth_gen_vec2/osmo_auth_gen_vec_auts2 API.
The rationale of this new API is to enable
* support for AKA algorithms which use K and/or OP[c] values of 256bit
(instead of the classic 128bit)
* support for RES length sizes of 4 and 16 bytes (instead of the classic
8 bytes)
This commit just jumps over to the new API without adding any related
functionality to osmo-hlr. The latter is left for subsequent commits.

So far we supported a "xor" algorithm in osmo-hlr, without specifying
whether it's the XOR-3G or the (different) XOR-2G algorithm.
Furthermore, it was buggy in the sense that it permitted the XOR[-3G]
for 2G authentication data in the database.
This patch
* renames existing "xor" to "xor-3g"
* disallows "xor-3g" usage with 2G authentication data
* introduces support for XOR-2G as "xor-2g" in the VTY

Places the individual msc node services in the
