*) 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.
