Vincent Sanders 1bc010665e Reduce unecessary use of directory entry headers
The config header was causing many source files to unecessarily
include the dirent headers causing extra dependancies. This has been
fixed by providing a utility dirent header that provides a common API
across all platforms while removing the unecessary dirent header usage.
