[patch] mod_setenvif r->notes--

[Doug MacEachern]

first hunk switches from using r->notes to r->request_config, which is
much faster.  and important considering that code runs at least twice for
every request if mod_setenvif is loaded.
second gets rids of a strcmp.  if there is a '!' in val, it will never be
more than that.
