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 new multiply() function detects range value overflows. 32bit
machines will overflow on a 32bit boundary while 64bit hosts support
ranges up to the full 64 bit range.
Added test 1236 to verify.
