Keith Packard 52048ce29f Xext/saver: Swap ScreenSaverSuspend 'suspend' field. Handle old XCB clients.
This field was defined as a Bool in the protocol headers and BOOL in
xcb. Bool is not a valid type for protocol fields. It is defined as
'int' by Xdefs.h, which we expect to be 32-bits on all machines.

The protocol headers and xcb have patches posted to switch to CARD32,
which is at least well defined.

This change adds the necessary byte swapping to handle other-endian
clients with this 32-bit field, and then changes the request
processing to compare all 32-bits against zero so that it works with
both new and old clients.

On MSB machines, Xlib will continue to work properly, but old XCB will
not interoperate with the X server (either before or after this patch).

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
