We need another guard, this may resolve a crash in the rather odd faux-server
implementation in mod_perl test suite which calls access checking too early.

Noticed via server-status for prefork showing request "NULL" after
keep-alive connections timed out.

during detection of libnghttp2. "ab" doesn't
yet support http2.

The macros were probably copied over from our
OpenSSL detection, where it actually makes
sense to adjust the "ab" flags.

  Ensure http2 follows http in the meaning of
  status WRITE (meaning 'in the request processing
  phase' even if still consuming the request body,
  not literally in a 'now writing' state).

  Ensure a number of MPMs and the h2 connection io
  no longer clobber the request status line during
  state-only changes.  While at it, clean up some
  very ugly formatting and unnecessary decoration,
  and avoid the wordy _from_conn() flavor when we
  are not passing a connection_rec.

  Ensure the useragent_ip is only used in the case
  where it has been initialized, fall back on the
  connection's remote_ip if the status is accidently
  updated from an uninitialized request_rec.

Revert to 2.4.1 behavior and null the request and vhost as appropriate.
