Konstantin Belousov 4f77f48884 Implement O_BENEATH and AT_BENEATH.

escaping the starting directory.  Supposedly the interface is similar
to the same proposed Linux flags.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
