Move files out of root into core, dos, and utils
Move source files out of the root directory; the root is a mess and
has become virtually unmaintainable. The Syslinux core now lives in
core/; the Linux and generic utilities has moved into utils/, and
copybs.com has moved into dos/; it had to go somewhere, and it seemed
as good a place as any.
