nginx-0.1.42-RELEASE import

    *) Bugfix: if the request URI had a zero length after the processing in
       the ngx_http_proxy_module, then the segmentation fault or bus error
       occurred in the ngx_http_proxy_module.

    *) Bugfix: the "limit_rate" directive did not work inside the "if"
       block; the bug had appeared in 0.1.38.
