Final sync of mod_rewrite for Apache 1.2.2:

  o added diff between mod_rewrite 3.0.6+ and 3.0.9
    minus WIN32/NT stuff, but plus copyright removement.
    In detail:
    - workaround for detecting infinite rewriting loops
    - fixed setting of env vars when "-" is used as subst string
    - fixed forced response code on redirects (PR#777)
    - fixed cases where r->args is ""
    - kludge to disable locking on pipes under braindead SunOS
    - fix for rewritelog in cases where remote hostname is unknown
    - fixed totally damaged request_rec walk-back loop
  o remove static from local data and add static to global ones.
  o replaced ugly proxy finding stuff by simple
    find_linked_module("mod_proxy") call.
  o added missing negation char on rewritelog()
  o fixed a few comment typos
