Fix test-order-dependend asyncio test failure caused by rev 909ea8cc86bbab92dbb6231668f403b7360f30fa.

* Repair the broken link to norobots-rfc.txt.

* HTTP response codes >= 500 treated as a failed read rather than as a not
found.  Not found means that we can assume the entire site is allowed.  A 5xx
server error tells us nothing.

* A successful read() or parse() updates the mtime (which is defined to be "the
  time the robots.txt file was last fetched").

* The can_fetch() method returns False unless we've had a read() with a 2xx or
4xx response.  This avoids false positives in the case where a user calls
can_fetch() before calling read().

* I don't see any easy way to test this patch without hitting internet
resources that might change or without use of mock objects that wouldn't
provide must reassurance.

in order to have the same resolution as pthreads condition variables.
At the same time, it must be large enough to accept 31 bits of
milliseconds, which is the maximum timeout value in the windows API.
A PY_LONG_LONG of microseconds fullfills both requirements.
This closes issue #20737
