Unix filedescriptor related utilties

Documentation at https://docs.rs/unix-fd/

mod fd

Provides basic functions around unix filedescriptors. Especially, it implements wrappers around openat() and related *at() syscalls.

mod dir

Implements fdopendir() and directory traversal functions for Unix filedescriptors.

mod chroot

Implements functions to access a directory in a chroot like way without requiring superuser permissions. E.g. it will resolve symlinks relative to the chroot top directory. Every traversal and lookup operation will be done in a secure (non-racy) way by using openat() and related functions.
