"force-response-1.0" now only applies to requests which are HTTP/1.0 to begin

with.  "nokeepalive" now works for HTTP/1.1 clients.  Added "downgrade-1.0"
which causes Apache to pretend it received a 1.0.  Additionally mod_browser
now triggers during translate_name to workaround a deficiency in the
header_parse phase.
