Needed for implementing drag'n'drop icons. When a drag starts, the
compositor will position the top-left corner of the client supplied
icon surface at the cursor hotspot. On the first attach to that
surface, the client may want to reposition it but shell->map did not
take sx and sy parameters.
This changes shell->map interface to take sx and sy parameters and
change dekstop shell implementation to update the position of a
surface of type none according to those parameters. Since a surface
of type none won't actually be mapped, the effect of this change is
only visible for surfaces that are made visible by the compositor.

Move the call to assign an output from weston_surface_configure() to
weston_surface_update_transform().
As update_transform takes new geometry into use, it should also reassign
the output for the surface, but only if an output was already assigned.
Add explicit assing output calls to where we relied on
weston_surface_configure() unconditionally assigning the output.

When a transformed (rotated) surface is continuously resized from its
top-left corner, its location will drift. This is due to accumulating
rounding errors in transforming an offset from surface-local to global
coordinates in surface_attach().
Diminish the drift down to unobservable level by changing the
weston_surface global position from integer to float.
The offset transformation is now done without rounding. To preserve the
precision, wl_shell::configure() interface must use floats, and so does
weston_surface_configure(), too.
The con of this patch is that it adds inconsistency to the surface
position coordinates: sometimes they are floats, sometimes integers.
weston_surface::transform.position depends on x,y, and therefore the
dirty flag, so move x and y into geometry.
Also add the missing dirty flags.

This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.
Add a new wlsc_shell API function for destroying the shell plugin
object. Helps to reduce Valgrind reports.

shell.c and tablet-shell.c had almost the same code for forking their
special shell client. Generalise this code and put it into
wlsc_client_launch() in compositor.c.
Improve error cleanup and reporting in wlsc_client_launch().

When compositor enters SLEEPING state, the shell plugin goes locked. If
compositor wakes up itself, it will fade in while the shell may not yet
have a lock surface to show.
Fix this by assigning wake-up to be called from the shell, if the
compositor is SLEEPING. The shell may wait for the lock surface request,
and only then wake up the compositor. The compositor will fade in
directly to the lock screen.

Add protocol and functions for supporting screen locking, triggered by
activity timeout.
After activity timeout, compositor starts the fade to black, and then
enters SLEEPING state. At that point it calls lock() in the shell
plugin.
When input events trigger a wakeup, unlock() in the shell plugin is
called. This sends prepare_lock_surface event to the desktop-shell
client. The screen stays locked while the compositor starts fade-in.
At this point, desktop-shell client usually creates a surface for the
unlocking GUI (e.g. a password prompt), and sends it with the
set_lock_surface request. The compositor supposedly shows and allows
interaction only with the given lock surface (not yet implemented).
When desktop-shell has authenticated the user, or instead of issuing
set_lock_surface, it sends the unlock request. Upon receiving the unlock
request, the shell plugin unlocks the screen.
If desktop-shell client dies, the screen is unlocked automatically.

The shell module only needs to deal with attach when it's either the initial
attach or when the attach changes the size of the surface. In case of
initial attach, the shell needs to pick a position for the surface and a
place in the surface stack. We split this case out as a new shell->map
callback. The other case is split into the shell->configure callback,
where the shell may adjust the surface position or reject the new size.
