Differentiate between "IMSI unknown" and "IMSI has no auth data": in case of
known IMSI lacking auth data, return -ENOKEY instead of -ENOENT.
Fix API doc comments to reflect what the functions actually return, on top of
adding the -ENOKEY detail.
Adjust db_test expectations from -ENOENT to -ENOKEY where appropriate.
Adjust VTY and CTRL command rc evaluation.
A subsequent patch will use these return values to log details on each of these
situations.

If we have a subscriber entry that lacks auth data, we currently return
GMM_CAUSE_NET_FAIL, which in the MSC log looks like the HLR is not connected or
something grave. Instead, return GMM_CAUSE_IMSI_UNKNOWN.
This changes the OsmoMSC log in this way:
Before:
DVLR <001e> VLR_Authenticate(901700000014701)[0x5555558dabb0]{VLR_SUB_AS_NEEDS_AUTH_WAIT_AI}: GSUP: rx Auth Info Error cause: 17: Network failure
After:
DVLR <001e> VLR_Authenticate(901700000014701)[0x5555558dabb0]{VLR_SUB_AS_NEEDS_AUTH_WAIT_AI}: GSUP: rx Auth Info Error cause: 2: IMSI unknown in HLR
A better cause value would be something that says "IMSI known, but we have no
auth data", but since such cause value is not defined, the plain "IMSI unknown"
seems to be the best match.

A user on openbsc@ complained that with SQLite 3.8.2, the db_test fails with
--- expected
+++ stderr
-DDB (2067) abort at 18 in [INSERT INTO subscriber (imsi) VALUES ($imsi)]: UNIQUE constraint failed: subscriber.imsi
+DDB (2067) abort at 35 in [INSERT INTO subscriber (imsi) VALUES ($imsi)]: UNIQUE constraint failed: subscriber.imsi
i.e. a trivial difference in the error message issued by SQLite.
For db_test, don't output any SQLite error messages: Add argument
enable_sqlite_logging, pass as true, except in db_test.c.
Remove the SQLite error messages from expected output.
(Note that there is a src/db_test.c program that's not of interest here, this
is about the tests/db/db_test.c)

It appears that hlr_subscriber.imsi is 16 buffers in size:
15 chars for IMSI + 1 byte NUL. However, osmo_gsup_message.imsi
is 17 bytes (for whatever reason), so we cannot simply do a strpy()
as this might overflow the hlr_subscriber.imsi field!
TODO: check if weactually ever receive a too-long IMSI in GSUP and
reject that at an earlier time in the code flow.

Use named parameters in the SQL statements.
Use db_bind_* functions to drop some code dup.
Adopt error handling (rc and logging) to match the other db functions: return
-ENOENT for unknown subscriber, -EIO for SQL failures.

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.

talloc output on each program exit as soon as we add a VTY (next patch).

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.
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.
We also introduce a 'gsup_router' which enables us to route
a transaction to a given VLR. It works based on the SERIAL attribute
communicated at time of the IPA multiplex setup as part of the CCM
sub-protocol.
