nginx-0.3.54-RELEASE import

    *) Feature: nginx now logs the subrequest information to the error log.

    *) Feature: the "proxy_next_upstream", "fastcgi_next_upstream", and
       "memcached_next_upstream" directives support the "off" parameter.

    *) Feature: the "debug_connection" directive supports the CIDR address
       form.

    *) Bugfix: if a response of proxied server or FastCGI server was
       converted from UTF-8 or back, then it may be transferred incomplete.

    *) Bugfix: the $upstream_response_time variable had the time of the
       first request to a backend only.

    *) Bugfix: nginx could not be built on amd64 platform; the bug had
       appeared in 0.3.53.
