Split proxy: space using <Proxy[Match] > directive blocks from

the <Directory[Match] > and <Files[Match] > blocks.  Mod_proxy
  now bypasses the directory and files testing phase (and skips
  the http TRACE default handler on it's own, as well).  Note that
  <Location > blocks continue to be processed for proxy: requests.

  Remaining questions include canonicalization and case folding
  of proxied uri space, prior to the proxy_walk testing and the
  second <Location > walk.
