Merge of r4621, r4641: filter_finalize fixes. *) Fixed possible request hang with filter finalization. With r->filter_finalize set the ngx_http_finalize_connection() wasn't called from ngx_http_finalize_request() called with NGX_OK, resulting in r->main->count not being decremented, thus causing request hang in some rare situations. Patch by Yichun Zhang (agentzh). *) Fixed segfault with filter_finalize introduced in r4621 (1.3.0). See the following thread for more details: http://mailman.nginx.org/pipermail/nginx-devel/2012-May/002190.html
