In LOGHLR and LOGAUC, log IMSI='<imsi>' instead of just <imsi>:
In the log, it is not always obvious to the reader that the printed number
refers to an IMSI (vs. an MSISDN or in the future an IMEI).
In db_get_auth_data(), log "No such subscriber" instead of just "Unknown", to
clarify what exactly is meant.

There are upcoming additions, and some seem too general without a proper common
prefix in the identifiers, like 'CREATE'.

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.

We can no longer accurately print the SQN from AUTS resync, since the SQN is
incremented after AUTS. Instead, always print the SQN from the generated tuple,
i.e. exactly the one left in auth data *after* the tuple was generated.
This change was forgotten in recent adjustments to the new SQN incrementing
scheme from libosmocore, in change-id I4ec5a578537acb1d9e1ebfe00a72417fc3ca5894
for libosmocore change-id Iadf43f21e0605e9e85f7e8026c40985f7ceff1a3.
It should have been obvious that something was missing in the previous patch
from the auc_test output: the SQN in the output changed while the AUTN remained
the same. That slipped by without being noticed :/

The database stores the key material as hex-ascii, we thus need to go
through osmo_hexparse() when reading. We could also store the material
as BLOB in the database. That would however complicate matters, as it
would basically mean using the sqlite3 command to manually
inspect/modify data from the console would no longer be easily possible.
Using this commit I have 2G authentication working against osmo-sgsn
with GSUP and 'auth policy remote'.
When responding to a SendAuthInfo.req, we need to differentiate
an error case caused by an unknown IMSI, or an error caused by
an error regarding accessing the database or data integrity.
