ussd: Send USSD on call setup on MSC errors
Send an USSD message to the mobile station requesting a connection
for a call or a SMS when the link to the MSC is down or in the
grace period.
The messages can be set (and this feature activated) by setting
bsc/missing-msc-text resp. msc/bsc-grace-text via the vty.
The generation of both messages has been tested manually.
Ticket: OW#957
