Replace the <port> tag with a construct in terms of <filename>:

<filename role="package">.  The <port> tag as it was had two major
defects: (a) the name is ambiguous (does "port" mean "architecture"?
how about "TCP/UDP port"?), and (b) it introduces a non-standard (to
DocBook) tag, which is generally assumed to be evil.
