Max c08ee71bff Move DTX settings to BTS
* Add per-BTS DTX settings
* Configure Uplink and Downlink DTX separately
* Deprecate global DTX option (it was never tested/used anyway)
* Use libosmocore function for DTX indicator in System
  Information (previously it was incorrectly assigned for half-rate
  channels)

Vadim Yanitskiy a8d8e93086 db.c: implemented incremental migration
In the past, normal migration was possible only if the actual
schema version differed from the version used in DB by 1. For
example, if DB uses an old version 3 and you need to use it
with the code written for version 5, the check_db_revision()
will convert it to 4 and DB will still use incompatible schema
version during Osmo-NITB running time. After next run it will
be converted to version 5.

This patch replaces a set of 'else-if' checks by a 'switch'
without 'break' statements between 'case' labels (waterfall).
It makes you able to migrate from current version to the
latest despite any difference between them.

Harald Welte 7c55ede8b1 Add human-readable name of SGSN_AUTH_AUTHENTICATE
In commit 4adb136da6 we introduced
a new authentication state SGSN_AUTH_AUTHENTICATE, but we didn't
add that to auth_state_names[] resulting in log messages printing
it abut 'unknown 0x1' rather than something more useful.

Harald Welte 5f2524fe3d sgsn/GSUP: Support MAP-style nested LU/ISD
The existing GSUP code expected the subscriber data to be piggy-backed
onto the location update response, rather than a separate (and nested)
insert subscriber data request/response phase.

With this patch we should now support both the nested as well as the
piggy-backed version.

Harald Welte 5d547a4358 osmo_oap_decode(): Use common argument ordering
In general, if a function generates output data like a msgb (or in this
case filling an osmo_oap_message structure), the output argument
precedes the source.  This is what we use all over libosmo*, and it is
modelled after memcpy(), where dst is the first argument, before src.

Let's align osmo_oap_decode().  Intestingly, osmo_oap_encode was already
correct, so the encode/decode functions used different conventions
before.

Harald Welte 121e9a4164 Start to use struct osmo_auth_vector from gsm_auth_tuple
Rather than having a 'private' structure for kc, sres and rand, we
now finally (with 4 years delay) use osmo_auth_vector from libosmogsm,
which encapsulates authentication vectors that can be either GSM
triplets or UMTS quintuples or a combination of both.

gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding
use_count and key_seq to it.

key_seq is no longer initialized inside gprs_gsup_messages.c, as there
is no CKSN / key_seq inside the message anyway.  If a usre of the code
needs key_seq, they need to manage it themselves.

Holger Hans Peter Freyther 9bcb1a56cb ctrl: Extend ctrl command to optionally handle alg+ki
Extend the existing ctrl command to be able to specify the
algorithm and Ki. In contrast to the VTY no size check is
done. Together with the VTY this code only supports a small
part of what is supported by libosmocore.

The algorithm and ki are considered optional but if a valid
algorithm other than "none" is passed, a KI must be passed as
well.

Extend the test coverage by passing the potential values. It
is not verified that the KI/algorithm is stored.

Holger Hans Peter Freyther 2826df56b2 subscr: Make db_create_subscriber fail on duplicates
The issue of db_create_subscriber updating an already existing subscr
is that the same subscriber will then have two entries in the active
subscribers list. In general this will break assumptions that a subscr
can be compared by comparing the pointer.

In the case of the VTY this was not an issue as the created subscr
was immediately destroyed again but it is better to avoid this problem.

Change the VTY command to find the subscriber and then call sync to
have the updated time set. The side-effect is we will now have two
queries for the subscriber. Once through subscr_get_by_imsi and once
through db_create_subscriber.

Change the db_create_subscriber to fail if a subscriber already exists,
and add a testcase for this behavior and do not updated the 'updated'
timestamp of an already existing subscriber.

Add a testcase for this behavior.

Neels Hofmeyr cf1302e4cb Fix MM Auth: zero-initialize auth tuple before first use
Make sure a new auth tuple is initialized after
db_get_lastauthtuple_for_subscr() returns an error, i.e. if no tuple is present
for the subscriber yet.

Before this patch, the first key_seq depended on the typically uninitialized
value that was present in auth tuple's key_seq upon calling
auth_get_tuple_for_subscr().

The very first key_seq used for a new subscriber will now always be 0. Before,
it used to be mostly 1 ("(0 + 1) % 7"), but depended on whether the key_seq was
indeed initialized with 0, actually by random.
