Data device interface in client just handle with pointer's dnd.
If a touch screen trigger dnd, it will use pointer struct like i
nput->sx, input->sy, input->pointer_focus. So if pointer is moving
when touch screen trigeer a dnd, wrong behaviore will occur.
Before touch screen start dnd, system call touch_grab()
to mark the following drag and drop operation is generated by
touch screen.
Defined some common variables in struct input to track dnd.
Note, touch screen and pointer can't generate drag and drop at the
same time, becuae data device protocol can't identify the drag
and drop event is generated by touch screen or pointer.

Adding the interface for touch screen event in clients/dnd.c, once
user touch down on this app, it will trigger a touch and drag
operation.

We used to have to composite the pointer on top of the drag icon, but
the final protocol allows us to specify both a drag icon and a cursor.
Remove the complexity that dealt with that.
Currently, the dnd sample client accepts all mime-types and assumes they
are the custom flower mime-type. Only accept if the offer has the right
mime-type.
Use wl_surface_commit() to commit the buffer attach, as Weston now
requires.
NOTE: GL-applications are broken until you upgrade to a version of Mesa
which does wl_surface_commit() on eglSwapBuffers(). If you have
Cairo-gl, this means all toytoolkit apps, too.
simple-shm and simple-touch OTOH will work now.

Instead of using a uint32_t for state everywhere (except on the wire,
where that's still the call signature), use the new
wl_pointer_button_state enum, and explicit comparisons.

Add option --self-only to dnd client. If this options is passed, the
drag will be started with no data source so that no drag and drop
events are sent to other clients.
If cairo-gl is used, display_create_surface() will create an
wl_egl_window for each surface and this will result in errors if this
surface is used as a source. Also, one can't get a wl_buffer for such
a surface wich led to crashes when trying to do so for the drag icon.
This patch works around both problems by forcing the item and drag icon
surfaces to use shm.
On one hand, getopt (in particular the -o suboption syntax) sucks on the
server side, and on the client side we would like to avoid the glib
dependency. We can roll out own option parser and solve both problems
and save a few lines of code total.
