Update from 1.5.4 to 1.5.5.
Remove needless entries for ngx_http_auth_request_module from distinfo, the
module is the part of main distro.
*) Change: now nginx assumes HTTP/1.0 by default if it is not able to
detect protocol reliably.
*) Feature: the "disable_symlinks" directive now uses O_PATH on Linux.
*) Feature: now nginx uses EPOLLRDHUP events to detect premature
connection close by clients if the "epoll" method is used.
*) Bugfix: in the "valid_referers" directive if the "server_names"
parameter was used.
*) Bugfix: the $request_time variable did not work in nginx/Windows.
*) Bugfix: in the "image_filter" directive.
Thanks to Lanshun Zhou.
*) Bugfix: OpenSSL 1.0.1f compatibility.
Thanks to Piotr Sikora.
