SUNRPC: Create API for displaying remote peer address
Provide an API for formatting the remote peer address for printing without exposing its internal structure. The address could be dynamic, so we support a function call to get the address rather than reading it straight out of a structure. Test-plan: Destructive testing (unplugging the network temporarily). Probably need to rig a server where certain services aren't running, or that returns an error for some typical operation.
