Infrastructure in STP_Tests_IPA changed to be more similar to what is
done in STP_Tests_M3UA, which already contain more advanced tests.
Array of AS names mp_ipa_as_names is added in order to let TTCN3 port
which AS is configured in STP for each src port.

In the past, we were automatically running [large parts of] the nplab
M3UA and SUA test suites, but those implement only a fraction of the
functionality. Particularly, they don't cover the non-standard IPA
behavior, and they don't cover RKM (routing key management).
Let's introduce an initial set of STP tests with this patch. We try
to not duplicate nplab here, and implement bits not covered there.
