Add ind_bitlen column to auc_3g to record each USIM's IND size according to
3GPP TS 33.102 -- default is 5 bits, as suggested by the spec.
Introduce auc_3g_ind to each connecting GSUP client to use as IND index for
generating auth tuples sent to this client.
With osmo_gsup_server_add_conn(), implement a scheme where clients receive
fixed auc_3g_ind indexes based on the order in which they connect; each new
connection takes the lowest unused auc_3g_ind, so in case one of the clients
restarts, it will most likely receive the same auc_3g_ind, and if one client
disconnects, no other clients' auc_3g_ind are affected.
Add gsup_server_test.c to test the auc_3g_ind index distribution scheme.

Todo for later: table subscriber_multi_msisdn possibly allows duplicating the
MSISDN, so we should drop this table or have all MSISDNs in one table separate
from 'subscriber'.

Notably this has no functional effect (according to
https://sqlite.org/faq.html#q9 ), but it can't hurt to indicate intent.

K is the SIM card's 128bit secret key, so the type should be VARCHAR like the
other key columns. The db code already reads the column as text and parses as
hex, so a VARCHAR column matches that.

Add configure.ac and Makefile.ams to build with
autoreconf && ./configure && make
like most other Osmocom projects.
Add jenkins.sh for a gerrit build job to verify patches.

Using this procedure, the VLR/SGSN can set the cs/ps purged
flag for the subscriber. We might not even need to store this
persistent in the database according to spec, but let's do it anyway, at
least until it turns out to be a performance issue.
SQLite has this crappy type system where you can put a string into
a boolean or integer column, which of course will break once you try to
read it as bool..
Also, add an index by IMSI to the SUBSCRIBER table.
