This tightens up the strtol() error checking in several places where it
is used for parsing environment variables, and in the backlight
interface that is reading numbers from files under /sys/class/backlight.
All of these uses are expecting strings containing decimal numbers and
nothing else, so the error checking can all be tightened up and made
consistent with other strtol() calls.
This follows the error checking style used in Wayland
(c.f. wayland-client.c and scanner.c) and c.f. commit cbc05378.

The third arg to strtol() specifies the base to assume for the number.
When 0 is passed, as is currently done in option-parser.c, hexadecimal
and octal numbers are permitted and automatically detected and
converted.
This change is an expansion of f6051cbab8
to cover the remaining strtol() calls in Weston, where the routine is
being used to read fds and pids - which are always expressed in base-10.
It also changes the calls in config-parser, used by
weston_config_section_get_int(), which in turn is being used to read
scales, sizes, times, rates, and delays; these are all expressed in
base-10 numbers only.
The benefit of limiting this to base-10 is to eliminate surprises when
parsing numbers from the command line. Also, by making the code
consistent with other usages of strtol, it may make it possible to
factor out the common code in the future.

This patch follows a similar approach taken to detach the backends from
weston. But instead of passing a configuration struct when loading the
plugin, we use the plugin API registry to register an API, and to get it
in the compositor side. This API allows to spawn the Xwayland process
in the compositor side, and to deal with signal handling. A new
function is added in compositor.c to load and init the xwayland.so
plugin.
Also make sure to re-arm the SIGUSR1 when the X server quits.

This patch adds a new command line option which can be

virtual outputs.
This will be used for output hotplug emulation, where
weston will start with no outputs available, and the
virtual output will be created at runtime.

- Use bool instead of int for the indicator flag
- Move final newspace to a separate line in command

This is the start of separating weston-the-compositor source files from
libweston source files.
This is moving all the files related to the 'weston' binary. Also the
CMS and systemd plugins are moved.
xwayland plugin is not moved, because it will be turned into a
libweston feature.
To avoid breaking the build, #includes for weston.h are fixed to use
compositor/weston.h. This serves as a reminder that such files may need
further attention: moving to the right directory, or maybe using the
proper -I flags instead.
v2: Move also screen-share.c, and add a note about weston-launch.

[Pekka: rebased]
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.

After the compositor exits the main loop in wl_display_run(), set the
compositor state to SLEEPING. This prevents scheduling repaints, that
will never be executed.
A repaint is scheduled by calling wl_event_loop_add_idle(), which
creates an idle event source. Normally the idle event source object is
destroyed after it has been executed. However, in the shutdown case we
never dispatch events again, and the object is leaked.
This leak is triggered by shell.c destructor, which destroys the
desktop-shell client. Destroying a client ends up calling
wlsc_compositor_schedule_repaint() while destroying the client
resources, especially surfaces.

This is the other direction. The selection bridge will grab the X11
CLIPBOARD selection on behalf of the Wayland client when it sets the
Wayland selection. Right now only UTF-8 text is supported, but the
data types offered will be taken from the Wayland data source.
We need to store all touchpoint positions so that if we just get an
ABS_MT_POSITION_X or Y event, we can pull the other coordinate from the
cache. And we need this across invocations of evdev_input_device_data(),
so the accumulator approach doesn't work.
Instead, we go back to the approach of storing all this state in the
evdev device struct and we might as well just move the rel and abs state
there too.
This adds ABS_MT_* support for direct touch devices and notifies
the compositor. The compositor has a stub for now.

fade_output() is strange in that it manufactures a wlsc_surface object
by hand, and then calls wlsc_surface_draw() on it.
Valgrind complained, that wlsc_surface_draw() accesses uninitialised
data: wlsc_surface::alpha. fade_output() forgets to set it.
Initialise surface.alpha in fade_output(). Specifically, set it to
compositor->current_alpha to deliberatly avoid the gluniform1f() call in
wlsc_surface_draw().
fade_output() binds a different GL shader program than
wlsc_surface_draw() expects. This program does not have a uniform called
"alpha", and the uniform location given in glUniform1f() is not for
this program anyway. A hint of that is the runtime error:
Mesa: User error: GL_INVALID_OPERATION in glUniform(type mismatch)
Fixing this seems to get rid of half a thousand of Valgrind errors, and
of course the Mesa user error.
