SunOS, IBCS2, Linux, and SVR4 all require translations of directory entries

from OpenBSD format to their respective native formats.

A lot of common code here for interfacing with OpenBSD VOP_READDIR. Most
of this code and logic has been moved to common/compat_dir.c

When reading a portion of the directory, the compatibility layer registers
a callback which is passed an OpenBSD-style dirent and the cookie/offset.
