SUNRPC: transport switch API for setting port number
At some point, transport endpoint addresses will no longer be IPv4. To hide
the structure of the rpc_xprt's address field from ULPs and port mappers,
add an API for setting the port number during an RPC bind operation.
Test-plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.
Probably need to rig a server where certain services aren't running, or
that returns an error for some typical operation.
