umts aka: add sqn_ms out-param, print SQN.MS in osmo-auc-gen
When doing UMTS AKA with AUTS, it can be interesting to know the SQN.MS that
    was encoded in the AUTS. The only way to know this is to provide it as a
    separate out-parameter from milenage_gen_vec_auts(), because the SQN.MS from
    AUTS stored in umts.sqn is immediately modified non-trivially by
    milenage_gen_vec(). Add sqn_ms to struct osmo_sub_auth_data to retain SQN.MS
    even after a vector was generated.
Use this to print out SQN.MS for 'osmo-auc-gen -3 -A'.
Adjust test suite expectations.

cosmetic: umts aka: tweak comments for sqn and ind
Clearly indicate that 'sqn' is an in *and* out-parameter.
Clarify the effect of 'ind'.

osmo-auc-gen: umts: print out the IND of the SQN used
Make ind_mask available in the main(){} scope, in order to print out
    IND = SQN & ind_mask.
Adjust test suite expectations.

osmo-auc-gen: umts: add --ind-len arg
osmo-auc-gen so far does not allow indicating the IND bit length of SQN. A
    default of 5 serves most practical cases, nevertheless we should allow passing
    arbitrary IND lengths.
Enhance the test suite to test --ind-len.

osmo-auc-gen: umts: add --ind arg
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.

osmo-auc-gen: umts: use default of ind_bitlen = 5 instead of 0
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: umts: properly request --sqn
The user supplied an --sqn to generate a vector for, but milenage_gen_vec()
    performs a nontrivial SQN increment before generating the vector. To end up
    with the user supplied SQN, we need to reverse this increment beforehand.
Do this after all cmdline args have been parsed, in case one of them modifies
    the IND-bitlen parameter, which affects the SQN calculations.

osmo-auc-gen: umts: remove erratic SQN.MS printout
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.
