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.

HAVE_LIBDRM was used as a condition for the launcher infrastructure to
call libdrm.so functions. It was set by an independent test for libdrm,
which would silently continue if libdrm was not found. It was assumed
that if you enabled a feature that used libdrm at runtime, the test for
that feature would imply that HAVE_LIBDRM is also set. This was quite
subtle.
The only feature that actually uses libdrm.so at runtime is the DRM
backend. No other backend needs the libdrm calls in the launcher
infrastructure.
Therefore to simplify things, stop using HAVE_LIBDRM and use
BUILD_DRM_COMPOSITOR instead. If you enable the DRM compositor, you
automatically also get libdrm support in the launchers.
There are still things depending on LIBDRM_CFLAGS and LIBDRM_LIBS, so
the test cannot be removed completely.

Bump the future release to 3.0.0 due to breaking ABI in libweston.
We have merged a few patches already that change libweston/compositor.h.
While most of the changes arguably change only things libweston users
should not be touching, some change the size of e.g. struct
weston_output and struct weston_compositor, possibly moving member
offsets. We also haven't separated public and private parts from
compositor.h yet. To be on the safe side, bump the major now. I'm sure
there will be more changes that make the bump obviously necessary.

This patch implements additional functionality that will be used
for configuring, enabling and disabling weston's outputs. Its
indended use is by the compositors or user programs that want to
be able to configure, enable or disable an output at any time. An
output can only be configured while it's disabled.
The compositor and backend specific functionality is required
for these functions to be useful, and those will come later in
this series.
All the new functions have been documented, so I'll avoid
describing them here.
v2:
- Minor documentation improvements.
- Rename output-initialized to output->enabled.
- Split weston_output_disable() further into
weston_compositor_remove_output().
- Rename weston_output_deinit() to weston_output_enable_undo().
- Make weston_output_disable() call two functions mentioned
above instead of calling weston_output_disable() directly.
This means that backend needs to take care of doing backend
specific disable in backend specific destroy function.
v3:
- Require output->name to be set before calling
weston_output_init_pending().
- Require output->destroying to be set before
calling weston_compositor_remove_output().
- Split weston_output_init_pending() into
weston_compositor_add_pending_output() so pending outputs
can be announced separately.
- Require output->disable() to be set in order for
weston_output_disable() to be usable.
- Fix output removing regression that happened when
weston_output_disable() was split.
- Minor documentation fix.
v4:
- Bump libweston version to 2 as this patch breaks the ABI.

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.

We are growing more tests that need to handle buffers, both just images
and wl_buffers. Particularly the screenshooting facility needs these.
Currently everything is in struct surface, which contains more than we
need. It is a bit messy.
Create a new struct buffer to encapsulate the image representation, the
wl_buffer, and enough information to tear it all down (munmap) so we
don't have to leak everything. Some tests might start doing things in
loops, and leaking would accumulate.
Instead of inventing our own image representation, use pixman_image_t.
It is a well-tested library worth using, and we already rely on it in
other places.
This makes the tests depend on Pixman, which requires the fix for
building buffer-count, which would otherwise not find pixman.h.
The new create_shm_buffer_a8r8g8b8() creates an image with an explicit
format, and pixman_image_t keeps track of it. And stride and size and
data. This implementation is still a little hacky due to calling
create_shm_buffer().
A very new thing is buffer_destroy(). Previously we didn't really free
any buffers. It is not a problem when the process will exit soon anyway,
but it may become a problem if tests start iterating things.
Manual memset() on a image is converted to a pixman action, just to show
how to do it properly with pixman.
Stride and pixel format assumptions still linger all around, but those
are for another patch.

This patch completely removes the Raspberry Pi backend and the renderer.
The backend and the renderer were written to use the proprietary
DispmanX API available only on the Raspberry Pi, to demonstrate what the
tiny computer is capable of graphics wise. They were also used to
demonstrate how Wayland and Weston in particular could leverage hardware
compositing capabilities that are not OpenGL. The backend was first
added in e8de35c922, in 2012.
Since then, the major point has been proven. Over time, support for the
rpi-backend diminished, it started to deteriorate and hinder Weston
development. On May 11, I tried to ask if anyone actually cared about
the rpi-backend, but did not get any votes for keeping it:
https://lists.freedesktop.org/archives/wayland-devel/2016-May/028764.html
The rpi-backend is a good example of how using an API that is only
available for specific hardware, even more so as it is only available
with a proprietary driver stack, is not maintainable in the long run.
Most developers working on Weston either just cannot, or cannot bother
to test things also on the RPi. Breakage creeps in without anyone
noticing. If someone actually notices it, fixing it will require a very
specific environment to be able to test. Also the quality of the
proprietary implementation fluctuated. There are reports that RPi
firmware updates randomly broke Weston, and that nowadays it is very
hard to find a RPi firmware version that you could expect to work with
Weston if Weston itself was not broken. We are not even sure what is
broken nowadays.
This removal does not leave Raspberry Pi users cold (for long), though.
There is serious work going on in implementing a FOSS driver stack for
Raspberry Pi, including modern kernel DRM drivers and Mesa drivers. It
might not be fully there yet, but the plan is to be able to use the
standard DRM-backend of Weston on the RPis. See:
http://dri.freedesktop.org/wiki/VC4/
The rpi-backend had its moments. Now, it needs to go. Good riddance!
