shell: modifier bindings configurable

This patch makes the main modifier configurable.  We used to hardcode super
(windows key) for most bindings, but now that can be changed.

The change affects two key bindings: rotation moves to mod+right click
and backlight moves to from ctrl+f9/f10 to mod+f9/f10.

shell: Move binding-modifier to shell section
compositor: Set pointer surface input region to empty on attach

We set up an emtpy region for the initial NULL-cursor, and then going
from no buffer to a 32x32 buffer didn't trigger the undeffing of the input
region.  So when something sets a cursor of a different size, the cursor
surface input region gets initialized and starts swallowing events.
compositor: introduce internal shell_interface

We're able now to create shell_surfaces inside Weston. This makes possible the
glue needed between shell and xserver-launcher.

On the desktop-shell, it was split the protocol part from shell_surface
specific functions to make this possible.

shell: Don't ping internal shell surfaces

This is a hack for now to get xserver surfaces working again.
xserver: Read window properties in map request handler
xserver: Move window property reading to set_window_id handler

This will work for override-redirect windows too.
Add COPYING

To ful-fill user experience, add the fading-in animation

Now we can choose zoom or fade in weston.ini
to fulfill and customize the user experence easier.

simple-shm: render meaningful diagnostics

Previously, simple-shm was rendering an image that looked like stride
gone wrong somewhere, and was quite confusing if you did not know it was
supposed to look like that.

Replace the drawing code. Two circles, inner and outer, now delimit
three co-centric areas. The outmost area from surface borders to outer
circle contains horizontal gradients that move (animate) to the left.
The area between outer and inner circles contains vertical gradients
that move upwards. The center disc has circular gradients moving towards
the center.

The circles are not ellipses.

Diagnostics:
The X-channel is manipulated so, that if a compositor takes the XRGB
image, and uses the X channel as alpha instead of ignoring it, the whole
image will be crossed out by two lines that either quickly saturate to
white or show through with additive blending. Does not work on black
background.

fix build for --disable-clients --enable-simple-clients

Simple clients were relying on AM_CFLAGS and AM_CPPFLAGS set for
toytoolkit clients. With toytoolkit clients disabled, the build fails
with missing wayland-client.h.

Move AM_CFLAGS and AM_CPPFLAGS outside of conditional sections, since
they are meant to be global settings.

Let simple clients override AM_CPPFLAGS with their own
SIMPLE_CLIENT_CFLAGS, which the configure script already sets up for us,
but was unused until now.

This variable is used unitialized if --xserver is not passed to weston.
