nginx-0.3.45-RELEASE import

*) Feature: the "ssl_verify_client", "ssl_verify_depth", and
       "ssl_client_certificate" directives.

    *) Change: the $request_method variable now returns the main request
       method.

    *) Change: the ° symbol codes were changed in koi-win conversion
       table.

    *) Feature: the euro and N symbols were added to koi-win conversion
       table.

    *) Bugfix: if nginx distributed the requests among several backends and
       some backend failed, then requests intended for this backend was
       directed to one live backend only instead of being distributed among
       the rest.
