Update the write handler for the portlist file to allow creating new
listening endpoints on a transport. The general form of the string is:
<transport_name><space><port number>
For example:
tcp 2049
This is intended to support the creation of a listening endpoint for
RDMA transports without adding #ifdef code to the nfssvc.c file.
The "built-in" transports UDP/TCP were left in the nfssvc initialization
code to avoid having to change rpc.nfsd, etc...
