Fixed portability issues with union sigval. AIO support in nginx was originally developed against FreeBSD versions 4-6, where the sival_ptr field was named as sigval_ptr (seemingly by mistake[1]), which made nginx use the only name available then. The standard-complaint name was restored in 2005 (first appeared in FreeBSD 7.0, 2008), retaining compatibility with previous versions[2][3]. In DragonFly, similar changes were committed in 2009[4], with backward compatibility recently removed[5]. The change switches to the standard name, retaining compatibility with old FreeBSD versions.
