[PATCH 2/2] Add keyboard shortcuts inhibitor

[Olivier Fourdan]

This adds a new protocol to let Wayland clients specify that they want
all keyboard events to be send to the client, regardless of the
compositor own shortcuts.

This is for use by virtual machine and remote connections viewers.

+	This protocol specifies a way for a client to request the compositor
+	to ignore its own keyboard shortcuts, so that all keyboard events
+	get forwarded to a surface.
+
+	Warning! The protocol described in this file is experimental and
+	backward incompatible changes may be made. Backward compatible
+	changes may be added together with the corresponding interface
+	version bump.
+	Backward incompatible changes are done by bumping the version
+	number in the protocol and interface names and resetting the
+	interface version. Once the protocol is to be declared stable,
+	the 'z' prefix and the version number in the protocol and
+	interface names are removed and the interface version number is
+	reset.
