In certain situations these clients crash a lot due to the low
buffer limit. Four buffers is also what EGL allows without blocking
and what is arguably the upper limit of what a compositor should
demand.

While this is harmless because gbm_bo_create_with_modifiers will just
fail, it's easy to misunderstand that gbm_bo_create_with_modifiers
accepts MOD_INVALID. Let's just keep modifiers_count to zero instead
and stop even trying to call that function with invalid input.
Stop using modifiers_count to decide whether the compositor supports a
format. Instead use a separate format_supported flag.

This header is for sharing fallback definitions for drm_fourcc.h. A new
test in tests/yuv-buffer-test.c is going to be needing XYUV8888 format,
and more new formats will be expected with HDR supports.
Share these fallback definitions in one place instead of copying them
all over.
All users of drm_fourcc.h are converted to include weston-drm-fourcc.h
instead for consistency: have the same definitions available everywhere.

MOD_INVALID came with libdrm 2.4.83 and MOD_LINEAR came with libdrm
2.4.82. libweston unconditionally depends on libdrm >= 2.4.95, so the
fallback is not necessary.
Since linux-dmabuf.h itself has no use for these and also forgets to
include drm_fourcc.h, .c files including drm_fourcc.h after this header
would trigger compiler warnings.
linux-dmabuf.c does need these, so add the proper include.

As dmabuf uses a different coordinate (top-left) system than OpenGL
(bottom-left) using both direct-display with the Y_INVERT dmabuf attrib
flag would result in the image being inverted (direct-display will
remove the Y_INVERT flag, which caused the image to be displayed
correctly). Notifies users that direct-display is in use.

Some drivers expose the extension so they can expose
eglQueryDmaBufFormatsEXT, but don't support any modifiers. Treat this the
same as if the extension wasn't present.
All these have the printf format string wrong. "%*s" sets the field width but
does not limit the string to len bytes. You need to set precision instead to
limit to len bytes: "%.*s".
Found by grepping, after wondering why my WIP prints printed garbage at the
end.

Support drawing a mandelbrot set in the fragment shader, rendering it
with separate draw calls, one for each cell in a virtual 4x4 grid. This
more complex and heavy drawing will potentially help us to visually

Add a client that uses EGL/GLESv2 to draw to dmabuf buffers, utilizing
EGLImages and FBOs. The client uses GBM to create the dmabufs buffers.
The simple-dmabuf-egl client is partly based on patch [1] that changes
dmabuf clients to use GBM instead of libdrm code, but has been greatly
simplified since in this case we don't require direct pixel access or
non-RGBA formats.

This makes --import-format=NV12 testable on e.g. intel
We only set nv12_format_found to true if we found that format and at
least one understood modifier. Store modifier verbatim instead of using
a boolean flag. Last advertised and supported modifier currently wins.
The NV12 DRM_FORMAT_LINEAR image should be green in the upper left

Use three buffers like simple-dmabuf-v4l instead of just two.
This is required, because when a frame callback arrives, the just
committed buffer is only on its way to the screen, while the previous
buffer is still being scanned out. It will take for the page flip to
complete, before the previous buffer is release. However, we want to be
able to repaint already at the frame callback, so three buffers can be
necessary.
This patch fixes weston-simple-dmabuf-intel to not abort with "Both
buffers busy at redraw()." when hardware overlays are used and the
surface gets directly scanned out.
