nginx-0.1.43-RELEASE import

    *) Feature: the listen(2) backlog in the "listen" directive can be
       changed using the -HUP signal.

    *) Feature: the geo2nginx.pl script was added to contrib.

    *) Change: the FastCGI parameters with the empty values now are passed
       to a server.

    *) Bugfix: the segmentation fault occurred or the worker process may
       got caught in an endless loop if the proxied or FastCGI server sent
       the "Cache-Control" header line and the "expires" directive was
       used; in the proxied mode the the bug had appeared in 0.1.29.
