If a client dies during a drag that it started using an icon surface,
the server could crash because the icon surface is not valid anymore.
Fix this by using a destroy listener to reset device->drag_surface to
nil when the surface is destroyed.
The listener function implementation was getting a wrong pointer to the
wl_data_offer object because the resource parameter is actually the
data source and not the data offer.
In order to separate pointer and keyboard grabs, we need to
introduce a keyboard grab interface but first we must rename
some generic types to denote which device is holding the grab.
Type renames:
wl_grab_interface -> wl_pointer_grab_interface
wl_grab -> wl_pointer_grab
wl_input_device_start_grab -> wl_input_device_start_pointer_grab
wl_input_device_end_grab -> wl_input_device_end_pointer_grab
In the effort to make everything a regular surface, remove
data_device.attach request. To maintan the functionality, add
an icon surface parameter to data_device.start_drag.
