[PULL wayland 0.85] signedness fixes and OS compatibility

[Pekka Paalanen]

Hi Kristian,

this patch series is divided in two:

The first part just enables compiler warnings, and then fixes or
silences them. One warning is left unfixed:
data-device.c:237:26: warning: comparison between signed and unsigned integer expressions
The fix for that would be

wayland-server.h
@@ -152,7 +152,7 @@ struct wl_grab_interface {
 	void (*motion)(struct wl_grab *grab,
 		       uint32_t time, int32_t x, int32_t y);
 	void (*button)(struct wl_grab *grab,
-		       uint32_t time, int32_t button, int32_t state);
+		       uint32_t time, uint32_t button, int32_t state);
 };

with all the follow-up fixes, but I'm not sure you want that in 0.85,
since it changes API.

The second part is adding compatibility wrappers for non-gnu/linux or
otherwise crippled operating systems. All the wrappers should compile
to the exact same code as before on our usual gnu/linux systems.
Overhead is added only if the needed features are not supported.

There is also a bug fix as the last patch.

If this series is acceptable, I will port it to wayland master branch,
too.
