Now we exclude a list of vars which we know for sure they
dont hold utf-8 chars; all other vars will be fixed. This
has the benefit that now also all vars from 3rd-party
modules will be fixed.

SECURITY (CVE-2011-3368): Prevent unintended pattern expansion in some
reverse proxy configurations by strictly validating the request-URI:

* server/protocol.c (read_request_line): Send a 400 response if the
  request-URI does not match the grammar from RFC 2616.  This ensures
  the input string for RewriteRule et al really is an absolute path.
