When reading along the article, the extra code added in the final
version is not explained. The main function calls flag.Parse(), for
example, which will cause an error, unless the readers looks at the
entirety of final.go to see the import added.
The file shown to the users no longer has the extra flags. The testing
code is now in a patch that gets applied to final.go in order to create
final-test.go. This is the file that will be used to test the code,
matching final.go as much as possible.

The original test would open a local port and then immediately close it
and use the port number in subsequent tests. Between the port being closed
and reused by the later process, it could be opened by some other program
on the machine.
Changed the test to run the server process directly and have it save the
assigned port to a text file to be used by client processes.
Fixes#5564.
