weston_compositor_init is always called late because most
implementations can't initialise GL until fairly late in the game.
Split it into a base version with the same name, followed by
weston_compositor_init_gl which can be called later on.
This simplifies compositor-wayland, which no longer needs a separate
global handler just for wl_seat.

EGLDisplay is helpfully typedeffed as void *, which means that you won't
get conflicting-pointer-type warnings if you accidentally confuse it
with weston_compositor::wl_display. Rename it to make it more clear
which display you're dealing with, and also rename compositor-wayland's
parent.display member to parent.wl_display.

Switching display mode may happen when:
1. The fullscreen surface is at top most in fullscreen layer and with
"driver" method. Shell will switch output mode to match the surface
size. If no matched mode found, fall back to "fill" method.
2. The top fullscreen surface is destroyed or unset. Switch back to the
origin mode.
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.
DPMS kicks in only when wscreensaver is launched, in the moment that shell
call lock() for the second time. Backlight control internals are managed by
libbacklight:

This allows each output back end to optimize drawing using overlay planes
and cursors (yet to be integrated). If a surface is assigned to a
plane, the back end should clear its damage field so that the later
repaint code won't look at it.
We've trimmed down the actual repaint loop to just iterating through the
surface list and calling weston_surface_draw(), so we push that to the
backend without too much code duplication.
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.
Besides the new header file, there's also a change in the main evdev creation
procedure for a more suggestive name (evdev_input_add_devices ->
evdev_input_create). There's no real functional changes in this commit.

All the compositors are using GLES2 so check for the appropriate
surfaceless extension.

Adds a general wlsc_compositor_shutdown() function that all output
backends call when shutting down. wlsc_compositor_shutdown() will call
a new 'destroy' method of each output to perform backend-specific
cleanup (e.g., turning off the hardware cursor in the DRM compositor).

I may have missed something, but - since the Wayland compositor
already picks a platform backend, opens a connection and initializes the
backend specific display data structure it doesn't make sense
to let egl pick a platform. If it picks a different one the
display specific data structure will most likely not match.
Thus determine the platform in the Wayland rendering backend by setting
the EGL_PLATFORM env variable.
For the client any other platform than 'wayland' doesn't seem to make
sense.
I'm not sure if I've got the the platform ofr openfwd right.
