Replace the current implementations of ftw() and nftw() with the OpenBSD
implementations written by Todd C. Miller. These are cleaner, less buggy
and actively maintained.

Add implementations of ftw(3) and nftw(3) and the corresponding header
ftw.h. This is the implementation written by Joel Baker
<fenton@debian.org> for inclusion in NetBSD, but with several
bugfixes.
