nginx: src/event/ngx_event_accept.c annotate

annotate src/event/ngx_event_accept.c @ 5263:05ba5bce31e0

Core: extended ngx_sock_ntop() with socklen parameter. On Linux, sockaddr length is required to process unix socket addresses properly due to unnamed sockets (which don't have sun_path set at all) and abstract namespace sockets.
