Adds custom call forwarding block while roaming carrier config key

Browse Source 
Adds support for supplying custom call forwarding prefixes in the carrier
config. When a prefix supplied in the carrier config is matched to the number
being dialed, we do not complete the call and instead show an error message
on the dialer UI.
