Added 3 commands:

smbmount: This is a stripped down smbclient that communicates with
the Linux 2.1.x kernel to supply authenticated smb connections for
smbfs mount points.
smbmnt/smbumount: setuid commands that do the actual smb mount system
call after having done the appropriate security checks
(This used to be commit ccbbc4e647ad900b215dae949d5bcd45671c68c8)
