Alexandros Frantzis e39eb8f896 libweston: Add check and fallback for linux/sync_file.h
The sync file functionality is required by the upcoming GPU render
timeline work, but it's only available in relatively new linux kernel
versions (4.7 and above).

This commit provides a "sanitized" version of the required sync file
definitions.  On systems that don't have the sync file header (due to
having an older kernel), we will be able to fall back to our own
definitions when building.

configure.ac: fix linking when using compiler sanitizers
The GCC address sanitizer overrides dlopen and dlclose, so the configure
test does not detect libdl as a needed dependency for linking. It is
still needed though, as dlsym is not exported by the sanitizer. The
result is that linking fails in the end.

Fix this by checking for dlsym instead of dlopen.

This can be reproduced by configuring the build with:
CFLAGS="-fsanitize=address -fsanitize=undefined"
LDFLAGS="-fsanitize=address -fsanitize=undefined"

demonstrate weston modifier advertising and import path using this
combination when run with --import-format=NV12.

Pekka Paalanen b030897b38 build: make libdrm a hard build-time dependency
Libdrm provides headers that are useful even without libdrm.so itself,
particularly drm_fourcc.h. Therefore promote libdrm as a hard build-time
dependency of libweston core so that we can always rely on libdrm
headers.

This does not affect any runtime dependencies. Specifically, no runtime
dependency to libdrm.so is added in any build configuration.

Currently only gl-renderer is using drm_fourcc.h. Now we can drop the
GL_RENDERER check from configure.ac and just use LIBDRM_CFLAGS.

Pekka Paalanen 4e3522bbd5 build: do not link libdrm without DRM backend
The pkg-config test for LIBDRM is independent of whether the DRM backend
is enabled or not. Therefore it is possible to have libdrm available and
found, even though it is not needed.

Do not link libdrm.so into the launchers unless it is really needed,
that is, DRM compositor is built. Otherwise you end up with
fbdev-backend.so and weston-launch depending on libdrm.so.

Quentin Glidic 642bcaf387 tests: add test-desktop-shell
This is a new desktop shell plugin, specifically written for tests. It
implements the bare minimum of a WM with predictable window positioning.
It offers a known static background without forking any helper clients
and therefore avoids any races with executing screenshot-based tests.
Not forking unused helper clients also reduces the load during a test
run.

The code was written by Quentin as a part of a much larger private
patch. Pekka, following Emilio's example, extracted just the shell
plugin parts as a stand-alone patch and wrote the commit message.

Daniel Stone 4938f93f57 tests: Remove buffer-count
buffer-count was introduced in line with a Mesa change which forced
an earlier block on frame events to try to enforce double-buffering
where available.

The Mesa change has since been reverted (Mesa commit 9ca6711faa), as
this had unpleasant interactions with buffer_age in particular, so this
test is no longer valid.

Additionally, it only worked on backends which initialised EGL (not
headless-backend, where tests generally run), which can be flaky due to
initialisation races. Not only that, but on the DRM backend, we can
legitimately enter triple-buffering due to promoting the surface to a
hardware plane, skipping GPU composition.

In light of all this, just remove the test.

Introduce libweston-desktop
libweston-desktop is an abstraction library for compositors wanting to
support desktop-like shells.

The API is designed from xdg_shell features, as it will eventually be
the recommended shell for modern applications to use.
In the future, adding new shell protocols support will be easier, as
limited to libweston-desktop.

The library versioning is the same as libweston. If one of them break
ABI compatibility, the other will too.

The compositor will only ever see toplevel surfaces (“windows”), with
all the other being internal implementation details.
Thus, popups and associated grabs are handled entirely in
libweston-desktop.
Xwayland special surfaces (override-redirect) are special-cased to a
dedicated layer, as the compositor should not know about them.

All the shell error checking is taken care of too, as well as some
specification rules (e.g. sizes constraint for maximized and fullscreen
surfaces).

All the compositor has to do is define a few callbacks in the interface
struct, and manage toplevel surfaces.

This patch implements the wp_pointer_constraints protocol used for

two requests; one for locking the surface to a position, one for
confining the pointer to a given region.

In this patch, only the locking part is fully implemented as in
specified in the protocol, while confinement is only implemented for
when the union of the passed region and the input region of the confined
surface is a single rectangle.

Note that the pointer constraints protocol is still unstable and as

Emil Velikov cbcf545fd9 libweston: don't install shared/platform.h
The header contains a set of extension check (helpers), which do not
provide any compositor related functionality and are not required for
using libweston.

Giulio Camuffo 9c764df043 xwayland: make the plugin usable by libweston compositors
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 Paalanen 827b5d225d compositor: add plugin-registry
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.
