If we destroy the text_input (e.g. due to surface deactivation) whilst
the IM manager (the client holding the input_method_context resource,
usually weston-keyboard) sends an event, we can hit a segfault in
text-backend. This is because we free the text_input structure, but
don't actually clear the context->input structure even when we send the
deactivate event.
This is clearly intended to be catered for, since context->input is
always checked for NULL before we relay any events.
This is enough to fix one cause of text-test failing, but it's
ultimately error-prone until we have a no-op test-shell; there is still
a race where weston-desktop-shell can launch weston-keyboard before
text-test manages to bind zwp_text_input_manager.

As it has been discussed in the past [1], running Weston
without any input device at launch might be beneficial for
some use cases.
Certainly, it's best for the vast majority of users (and
the project) to require an input device to be present, as
to avoid frustration and hassle, but for those brave souls
that so prefer, this patch lets them run without any input
device at all.
This introduces a simple configuration in weston.ini:
[core]
require-input=true
True is the default, so no behavioral change is introduced.

takes an output that's to be configured, default configuration
that's to be set in case no configuration is specified in

parsed_options, which will override defaults and options for
configuration if they are present.

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

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.

[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.
