[PATCH] libosmocore[master]: milenage_test: enhance to verify new SQN increments

[Neels Hofmeyr]

Hello Harald Welte, Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/2050

to look at the new patch set (#3).

milenage_test: enhance to verify new SQN increments

After the legacy mode incrementing with ind_bitlen == 0 is through, do another
AUTS run with sensible ind_bitlen and ind, and then two more normal vector
generations to verify proper SQN increments.
