WIP: msc/USSD: add multi-transaction testcase
The idea of this testcase is to establish a dedicated connection,
perform location update, and then send 8 USSD requests on 8
separate transactions at once. A few requests contain known
'*#100#' request code, others are intentionally wrong.
Finally, we expect that each received response shall correspond
to its request and shall be sent back on a proper transaction.
