    xenstore: rename XS_DEBUG wire command
    
    In preparation to support other than pure debug functionality via the
    Xenstore XS_DEBUG wire command rename it to XS_CONTROL and make
    XS_DEBUG an alias of it.
    
    Add an alias xs_control_command for the associated xs_debug_command,
    too.
