Several tests referred to specific server ports even when the test
didn't actually use that server or specify that it's needed. In such
cases, the test harness substitutes the text "[not running]" as the port
number which causes many such tests to fail due to the inability to
parse the URL. These tests are changed to use %NOLISTENPORT which will
always be substituted correctly.
The purpose with this variable is to provide a port number that is
reasonably likely to not have a listener on the local host so that tests
can try connect failures against it. It uses port 47 - "reserved"
according to IANA.
Updated six tests to use it instead of the previous different ports.

are not, due mainly to the lack of support for XML character entities
(e.g. & => & ). This will make it easier to validate test files using
tools like xmllint, as well as edit and view them using XML tools.
