Implement a simple register and lookup for function tables. This is
intended for plugins to expose APIs to other plugins.
It has been very hard to arrange a plugin to be able to call into
another plugin without modifying Weston core to explicitly support each
case. This patch fixes that.
The tests all pass.

This clarifies what is supposed to be the libweston code.
v2: screen-share.c is already in compositor/ instead.

[Pekka: rebased]
Using the parent '../' path component in #include statements makes
the codebase more rigid and is redundant due to proper -I use.

There was an issue recently in screen-share.c where config.h was not
being included, resulting in the wrong definition for off_t being used on
32 bit systems. I checked and I don't think this problem is happening
elsewhere, but to help avoid this sort of problem in the future, I went
through and made sure that config.h is included first whenever system
headers are included.
The config.h header should be included before any system headers, failing
to do this can result in the wrong type sizes being defined on certain
systems, e.g. off_t from sys/types.h

This has a couple of additional implications for the internal weston API:
1) weston_view_configure no longer exists. Use weston_view_set_position
instead.
2) The weston_surface.configure callback no longer takes a width and
height. If you need these, surface.width/height are set before
configure is called. If you need to know when the width/height
changes, you must track that yourself.
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

surface-global-test and surface-test did not get updated to
the new module_init(...) signature when it changed in
a50e6e4c50. Thus, they
failed to compile. Simply running 'make check' shows the
problem. This patch fixes it.

The remaining module tests don't need to fork and talk to a test client,
so just convert them to regular modules and let them handle running their
tests themselves. Then drop test-runner.[ch].
Compositor core does not do anything with udev, so the header is not
needed there. Move the #include into evdev.h, from where it gets used by
compositor-drm.c, too.
Also fix the fallout:
tty.c: In function 'tty_create':
tty.c:143:2: warning: implicit declaration of function 'fstat'

We dont want to receive hotplug events while being inactive.
When getting back active we enumerate all devices and would end up
with two sources for one device that may be hotplugged in the mean time.
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.
