This is a new function exporting macro that intends to make writing unit
tests in the Weston test suite easier.
A test needs to access a private function to be able to verify its
behavior. Previously we have used things like putting such functions in
a separate .c file and then building that file into the corresponding
test. That is a bit awkward and can lead to proliferation of arbitrary
.c files for no good reason. It may also require pre-processor magic,
and sometimes copying chunks of code causing a risk of deviating the
code being tested from the code actually used.
This patch proposes another approach: a private export from a DSO.
Except, private exports do not really exist, and this is just a normal
export with a specific C macro, and omitting the function from public
headers.
Once exported, a test program can link the DSO during build, be that a
shared library or even a plugin, use the private header declaring the
function, and simply call the function in the test.
The declaration of WESTON_EXPORT_FOR_TESTS is in shared/helpers.h so
that it is available to all components equally while still not being in
a public header. Other places that were considered:
- include/libweston/libweston.h is a public header, but external users
should not know about the macro.
- libweston/libweston-private.h is too private and not available to all
components, particularly color-lcms plugin.
- libweston/backend.h is not appropriate for color-lcms plugin either.

In commit "backend-drm: simplify compile time array copy", the macro
ARRAY_COPY was introduced.
The macro STRING was accidentally introduced in the same commit, and as
it is completely unnecessary, remove it.
Also, memcpy was copying from src to dst, and it should do the opposite.
So fix it.

In drm_fb_get_from_dmabuf() we have some compile time array copies, and
multiple static_assert() calls are needed (for safety). This makes the
code unpleasant to read.
Add ARRAY_COPY macro, to simplify the code.

Collect the fallback definitions of static_assert() from desktop-shell
and the test shell, and move them to helpers.h. This allows code
throughout the tree to use static_assert() for build-time assertions,
where it is supported by the compiler.
As GCC goes out of its way to only add static_assert() when C11 has been
explicitly requested - which we don't do - make sure to use the more
widely available _Static_assert() if that is provided.
This will be used in future patches to ensure two array lengths don't go
out of sync.

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.
