GdkWaylandDeviceData conceptually gathers the data that belongs to
a seat, so it's been renamed (although the old typedef stays, plenty
of refactoring is due here...).
The methods in GdkSeatClass have also been implemented, the most
remarkable is ::grab, which ensures the grab is performed on all
the relevant "master" devices.

Instead of having our own copy of the pointer gestures XML file, use
the one installed by wayland-protocols.
Since pointer gestures is an unstable protocol, it went through the
unstable protocol naming convention changes, which is reflected in this
commit.

Pick up the setting from the org.gnome.desktop.wm.preferences schema
if available. It is slightly more involved than other settings, as
the actual button names used in the schema differ from the ones we
use, so we need an additional translation step.

Some symbols in the generated Wayland code were getting
decorated with WL_EXPORT, causing them to show up in the
libgdk exports. We don't want that.

Change the visibility handling to be the same way we do it in
GLib now. We pass -fvisibility=hidden to gcc and decorate public
functions with __attribute__((visibility("default"))).
This commit just does this for GDK, GTK+ will follow later.
