- Moved (u)mount prototypes from unistd.h to sys/mount.h.

- Prepared mount system call to accept multiple mount flags
   instead of just read_only (however, it remains backwards
   compatible).
 - Updated the man mount(2) to reflect new header file usage. 
 - Updated badblocks, newroot, mount, and umount commands to use the
   new header file.
