SUNRPC: Clean up RPCBIND_MAXUADDRLEN definitions
Clean up: Replace the single-integer definition of RPCBIND_MAXUADDRLEN
with a definition that is based on previously defined address string
sizes, and document the way this maximum is calculated. Also provide
a separate macro for the size of the port number extension.
