During UMTS AKA, the caller typically indicates which IND slot the next used
SQN should belong to. Without this option, osmo-auc-gen will always produce SQN
from IND-slot 0. Add --ind option.
Enhance the osmo-auc-gen_test.sh to expect errors with useful printouts on
stderr, and add tests that verify valid --ind ranges.

Most USIM out there seem to use IND-length = 5 bits, so do sysmousim-sjs1.
Currently from initialization we are using an IND length of zero in
osmo-auc-gen, which produces confusing SQN results after AUTS:
Where want SQN to be incremented to the next IND array, usually +32, an IND-len
of 0 makes for only +1.
As result, the osmo-auc-gen_test.sh produces SQN 32 instead of 24 after
receiving SQN.MS = 23 from AUTS: adjust test expectations.

osmo-auc-gen tries to be helpful by deriving the SQN.MS from the SQN that
resulted from AUTS + milenage_gen_vec(), but there is actually no way to derive
the actual AUTS SQN.MS from the resulting SQN.
Completely drop the printout to prevent confusion.
Adjust test suite expectations.

Upcoming patches will change the way SQN are incremented. Change the SQN
related output by osmo-auc-gen so that it also makes sense after these changes,
and so that its output is proven to remain unchanged for the same arguments:
Always show the SQN used for vector generation when a UMTS vector was generated.
Don't show the next SQN, it will not make sense anymore (see later patches).
The adjustments of expected output of osmo-auc-gen_test illustrates how the
output changes.

Add test for osmo-auc-gen invocations to ensure stability across upcoming SQN
increment scheme changes.
The test comprises of a shell script that invokes the osmo-auc-gen binary with
various milenage parameters, of which the stdout/stderr are verified.
More osmo-auc-gen invocations could be added, but my main focus is on the SEQ
changes. Instead of manually testing that it still works for each SQN patch, I
want this test to do it for me.
To make sure that osmo-auc-gen is build before the tests are launched, place
'utils' before 'tests' in the root Makefile.am.
