This was used gala to implement hot corners, and the way the barrier API
works, there isn't really any practical reasons to not make it
derivable, since the backend is a separate type and object.

This adds a copy of the calibration test profile and sets up a test to
first add it as a system profile, then setting up the XDG_DATA_HOME
directory so that the duplicate profile is detected, added, and later
discarded.

We might fail with some part of the color profile construction and
initialization. For example there might be a system wide profile with
the same ID as one we attempt to add from a local ICC directory. When
this happens, we should drop these profiles, and use the ones from the
system instead.
Profiles may fail to initialize for other reasons too, e.g.
unpredictable colord errors, or other I/O issues.

If our profile wasn't fully initialized, we'd try to clean it up, in an
attempt to handle race conditions by finding synchronously then cleaning
it up, but don't attempt this if the profile is ready, as that means we
didn't create one in the first place.

This is instead of getting anything from the CdDevice. This avoids a
crash when CdDevice isn't successfully setup but something still tries
to look up the filename of the ICC profile.
This isn't a real bug fix for anything, but there is no reason having to
rely on CdDevice for this anyway, and as we don't really have control of
it, it's less reliable of containing something valid.

When creating a render device, we create a temporary EGLContext where we
then query the `GL_RENDERER` string to check whether the renderer is any
of the known software renderers. After we're done, we destroy the
context and move on.
This should be fine as according to specification eglDestroyContext(),
with the context being actually destroyed a bit later when it's no
longer current, but mesa, when running RK3399 (Pinebook Pro), this
results in a crash in a future eglMakeCurrent():
#0 in dri_unbind_context () at ../src/gallium/frontends/dri/dri_context.c:266
#1 in driUnbindContext () at ../src/gallium/frontends/dri/dri_util.c:763
#2 in dri2_make_current () at ../src/egl/drivers/dri2/egl_dri2.c:1814
#3 in eglMakeCurrent () at ../src/egl/main/eglapi.c:907
...
We can avoid this, however, by calling eglMakeCurrent() with
EGL_NO_CONTEXT on the EGLDisplay, prior to destroying, effectively
avoiding the crash, so lets do that.

We'll never scan out, which is why ADDFB2 is required otherwise, and we
won't enable the DMA buffer extension if
'EGL_EXT_image_dma_buf_import_modifiers' is missing, so send modifiers
in this case.
This also happens to avoid crashing when the GPU is null, since we'd
otherwise attempt to dereference it.

EGLStream is incompatible with atomic mode setting, but nvidia-drm when
using libgbm is not, so lets only deny using atomic mode setting when
the render device is an EGLStream based one.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2578>
The type of render device used for a specific GPU affects the mode
setting backend that can be used, more specifically, when the render
device is an EGLStream based one, atomic mode setting isn't possible, as
page flipping is done via EGL, not via atomic mode setting commits.
Preparing the render devices before KMS devices means can make a more
informed decision whether to deny-list atomic mode setting for when
a certain GPU uses a EGLStream based render device instance.
This also means we need to translate mode setting devices to render node
devices when creating the render device itself, as doing it later when
creating the mode setting device is already too late.

Doing an early out in a constructed() is a bit awkward, and unexpected,
and makes it tricky to call the parents constructed() method (which we
didn't), so clean that up.
