- Make Texture a parent GObject class and move the vtable funcs as vfuncs
instead of an interface as we would like to have dispose free the TextureLoader.
- Make the various texture sub-types inherit from it.
- Make all the sub-types constructors return a CoglTexture instead of their respective
specific type. As most of the times, the used functions accept a CoglTexture,
like all the GTK widgets constructors returning GtkWidget.
- Fix up the basics of gi-docgen for all these types.
- Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood.
- Remove CoglMetaTexture: for the exact same reason as above.
- Switch various memory management functions to use g_ variant instead of the cogl_ one
Note we would still want to get rid of the _cogl_texture_init which is something
for the next commit

So they can be derived from the DRM format as well.
While updating the users, ensure we don't announce support for
DRM formats in zwp_linux_dmabuf_v1 if the MetaMultiTextureFormat is
INVALID. This will be used for YUV subformats in following commits.

1. Move into the new 'common' folder and build for Wayland as well
so we will be able to share the code in follow-up commits.
2. Rename to cogl-drm-formats to make it more obvious that the format
map is more than an utility these days.
3. Drop the unused CoglTextureComponents part (see also previous
commit).
4. Move the map to the header, simplifying some future use-cases.
5. Sync formats with MetaWaylandBuffer and MetaWaylandDmaBufBuffer and
also use newly introduced opaque formats where appropriate.
This avoids duplicated code, ensures that new drm-formats added to
the dmabuf protocol have an adequate representation in Cogl from which
information like alpha support can be easily derived and finally
ensures we don't crash if the mappings got out of sync.
6. Remove some likely untested formats. In case some of these are
actually needed on certain hardware, we can test whether we got
the correct mapping by also adding support for the corresponding
wl_shm_format in MetaWaylandBuffer by extending the gradient test in

The previous logic didn't work correctly at least when priority-based
preeption wasn't supported by the DRM driver, such as in the case
of amdgpu. The call to glGetQueryObjecti64v would block on client
work which is already in progress (most likely for the next frame)
and delay notifying the ClutterFrameClock about presentation.
Conveniently, the Wayland transactions mechanism guarantees that all
fences of a dma-buf buffer are signalled before the buffer is
included in a frame, which means that dma-buf buffers are ready for
presentation when being directly scanned-out.
Direct scanout is only supported for dma-buf buffers too, which means
that all buffers going through direct scanout are effectively ready
and require no GPU rendering before presentation.
Assuming zero rendering time for dma-buf buffers going through direct
scanout simplifies the code and removes the need for
glGetQueryObjecti64v, thus avoiding the aforementioned issue where it
could block for longer than expected.

A failing allocation is non-fatal here, however if it fails later in a
lazy allocation triggered by `cogl_framebuffer_create_timestamp_query()`
we end up crashing. Thus force the allocation early, like we already do
in other places.

This means objects have an owner, where the chain eventually always
leads to a MetaContext. This also means that all objects can find their
way to other object instances via the chain, instead of scattered global
singletons.
This is a squashed commit originally containing the following:
cursor-tracker: Don't get backend from singleton
idle-manager: Don't get backend from singleton
input-device: Pass pointer to backend during construction
The backend is needed during construction to get the wacom database.
input-mapper: Pass backend when constructing
monitor: Don't get backend from singleton
monitor-manager: Get backend directly from monitor manager
remote: Get backend from manager class
For the remote desktop and screen cast implementations, replace getting
the backend from singletons with getting it via the manager classes.
launcher: Pass backend during construction
device-pool: Pass backend during construction
Instead of passing the (maybe null) launcher, pass the backend, and get
the launcher from there. That way we always have a way to some known
context from the device pool.
drm-buffer/gbm: Get backend via device pool
cursor-renderer: Get backend directly from renderer
input-device: Get backend getter
input-settings: Add backend construct property and getter
input-settings/x11: Don't get backend from singleton
renderer: Get backend from renderer itself
seat-impl: Add backend getter
seat/native: Get backend from instance struct
stage-impl: Get backend from stage impl itself
x11/xkb-a11y: Don't get backend from singleton
backend/x11/nested: Don't get Wayland compositor from singleton
crtc: Add backend property
Adding a link to the GPU isn't enough; the virtual CRTCs of virtual
monitors doesn't have one.
cursor-tracker: Don't get display from singleton
remote: Don't get display from singleton
seat: Don't get display from singleton

This handle is used by the legacy KMS API; lets avoid having to have GBM
specific code where this is done by letting the MetaDrmBuffer API, that
already has this information, expose it.

Because both code paths require the existence of `GL_TIMESTAMP[_EXT]`
which is only guaranteed if `ARB_timer_query` (included in GL core 3.3)
is implemented.
We know when that is true because `context->glGenQueries` and
`context->glQueryCounter` are non-NULL. So that is the minimum
requirement for any use of `GL_TIMESTAMP`, even when it is used in
`glGetInteger64v`.
Until now, Raspberry Pi (OpenGL 2.1) would find a working implementation
of `glGetInteger64v` but failed to check whether the driver understands
`GL_TIMESTAMP` (it doesn't).

It might not be needed by the user of the buffer, so don't always
require it up front. Instead make sure that any user that needs it first
calls "meta_drm_buffer_ensure_fb_id()" to create the ID.
Only the plain gbm implementation creates the ID lazilly, the other
still does it on construction due to the objects used to create them
only existing during construction.

Mostly calls into gbm_bo_* API, or something somewhat similar when on
dumb buffers. Added API are:
* get offset for plane
* get bpp (bits per pixel)
* get modifier
This will allow users of MetaDrmBuffer to avoid having to "extract" the
gbm_bo to get these metadata.

Scanout doesn't go through the usual path of compositing and doing
eglSwapBuffers, therefore it doesn't hit the timestamp query placed in
that path. Instead, get the timings by binding the scanout buffer to an
FBO and doing a timestamp query on the FBO.

The DRM buffers aren't really tied to mode setting, so they shouldn't
need to have an associated mode setting device. Now that we have a
device file level object that can fill this role, port over
MetaDrmBuffer and friends away from MetaKmsDevice to MetaDeviceFile.

This commit consolidates DRM buffer management to the MetaDrmBuffer
types, where the base type handles the common functionality (such as
managing the framebuffer id using drmModeAdd*/RMFb()), and the sub types
their corresponding type specific behavior.
This means that drmModeAdd*/RmFB() handling is moved from meta-gpu-kms.c
to meta-drm-buffer.c; dumb buffer allocation/management from
meta-renderer-native.c.

This will be used when screencasting monitors so that if
there's scanout in place, it'll still be possible to blit
it to a PipeWire-owned framebuffer, and stream it.
Add a new 'blit_to_framebuffer' vfunc to CoglScanout, and
implement it in MetaDrmBufferGbm.

Instead of always swapping buffers and flipping the back buffer, make it
possible to scan out a provided buffer directly without swapping any EGL
buffers.
A buffer is passed as an object implementing the empty CoglScanout
interface. It is only possible to do this in the native backend; and the
interface is implemented by MetaDrmBufferGbm. When directly scanned out,
instead of calling gbm_surface_lock_front_buffer() to get the gbm_bo and
fbid, get it directly from the MetaDrmBufferGbm, and use that to create
the page flip KMS update.

Surface buffers are created with meta_drm_buffer_new_acquire(), taking a
gbm_surface acquiring the gbm itself, and meta_drm_buffer_new_take()
that takes over ownership of a passed gbm_bo.

With all the three paths this is quite a handful of code, and it was mostly
duplicated in two places. A follow-up patch would need to introduce a third
copy of it. Therefore move the code into a helper function.
There are two behavioral changes:
- The format error now prints the string code as well, because it is easy to
read.
- The g_debug() in init_dumb_fb() is removed. Did not seem useful.

There is no reason why we should have an internal type enum when we have
all the infrastructure to just use multiple GObject types. Also there
was no code sharing between the old "types", the only common API was
getting the framebuffer ID, so lets make that a vfunc.
