[syslinux] Syslinux modification to not use mount, but write the file directly

[Marko Kohtala]

I reimplemented the syslinux.c such that it writes the file directly to 
the disk or disk image.

Would you be interested in taking it into syslinux? I have to ask 
because if you'd accept it, I need to make sure my employer has no 
objection. They have no interest in the program, but I have to go 
through the procedure anyway.
