Truncation detection in sendfile() on Linux.
This addresses connection hangs as observed in ticket #504, and
CPU hogs with "aio threads; sendfile on" as reported in the mailing list,
see http://mailman.nginx.org/pipermail/nginx-ru/2016-March/057638.html.
The alert is identical to one used on FreeBSD.
