[Xen-devel] [PATCH v2 1/5] xenstore: rename XS_DEBUG wire command

[Juergen Gross <jgross@xxxxxxxx>]

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.
