As explained in "egl/wayland: add initial dma-buf feedback support", we
still don't use the per-surface dma-buf feedback. In this patch we start
to use it.
If per-surface dma-buf feedback is advertised, use it to allocate
surface buffers. Also, the dma-buf protocol states that the feedback is
resent only when the client is using a suboptimal format/modifier pair.
So listen for new per-surface feedback events and reallocate the surface
buffers based on them. We can't change the format of a buffer, but we
can pick a new modifier.
This patch is based on previous work of Scott Anderson (@ascent).

In get_back_bo() we have two calls to loader_dri_create_image() and some
overhead. As in the next commit we add another call to this same
function and more overhead to get_back_bo(), it starts to lose
legibility.
So move loader_dri_create_image() calls to separate functions, allowing
us to have an easier to read get_back_bo(). It also adds some minor
style changes.

This bumps the supported dma-buf version up to 4 and adds the initial
dma-buf feedback implementation. It follows the changes in the dma-buf
protocol extension [1] to include the dma-buf feedback interface, which
should be incorporated by most Wayland compositors in the future.
From version 4 onwards, the dma-buf modifier events are not sent by the
compositor anymore, so we use the default feedback to pick the set of
formats/modifiers supported by the compositor. Also, we try to avoid the
wl_drm device event and instead use the dma-buf feedback main device. We
only fallback to wl_drm when the compositor advertises a device that
does not have a render node associated.
In this initial dma-buf feedback implementation we still don't do
anything with the per-surface dma-buf feedback, but in the next commits
we add proper support.
It's important to mention that this also bumps the minimal supported
version of wayland-protocols to 1.24, in order to include [1].

Most Wayland compositors have already implemented the dma-buf protocol
extension. So we can stop relying on the wl_drm events and start to
depend only on the dma-buf interface to receive format/modifier pairs
and create wl_buffer's. So we can deprecate drm_handle_format() and
drm_handle_capabilities().
Note that we still use the wl_drm interface to find out the DRM device
that the compositor is using, so we can't deprecate it fully for now. In
the future (when the dma-buf feedback interface is added to the dma-buf
protocol extension [1] and most compositors incorporate it) we may be
able to fully deprecate wl_drm.

Currently we have a weird design. We have a hardcoded array (named
dri2_wl_visuals) with all the formats that we support, which are 9.
And we also have EGL_DRI2_MAX_FORMATS, which is a constant set to 10. In
patches in which people added new formats to dri2_wl_visuals, this
constant had its value increased. This is confusing, as its name gives
the idea that we can't support more formats.
This constant is only used to define the bitset size of
dri2_egl_display::formats. And it should work just fine if we created
this bitset with the number of formats supported.
To make things clearer, replace EGL_DRI2_MAX_FORMATS by
EGL_DRI2_NUM_FORMATS, which must be equal to ARRAY_SIZE(dri2_wl_visuals)
(i.e. the number of supported formats).
In the next commits we get rid of this constant completely, as it is
prone to errors.

The following chain of events results in an incorrectly sized buffer
persisting beyond its useful lifetime, and causing visual artifacts.
buffer is attached at size A
window is resized to size B
rendering takes place for size B
window is resized back to size A
swapbuffers with damage is called
In this scenario, update_buffers fails to recognize that the surface it's
about to commit is a different size than it has rendered. The
attached_width and attached_height are set incorrectly, and periodic
flickering is observed.
Instead, we set a boolean flag at time of resize and use this at the time
we latch the window dimensions as surface dimensions to decide whether to
discard stale buffers.

egl: stop claiming support for pbuffer + msaa
This fixes a crash in egl-create-msaa-pbuffer-surface Piglit test
and same crash in many dEQP EGL tests.
Whatever bug that was papering over appears to be fixed by now, I can
no longer reproduce that crash with piglit. Furthermore, disabling that
bit in the generic dri2 code had the side effect that the surfaceless
platform would advertise EGLConfigs with _no_ supported surface types
(since surfaceless only supports pbuffers).

When EGL_KHR_mutable_render_buffer extension is enabled, advertised
configs unconditionally include EGL_MUTABLE_RENDER_BUFFER_BIT_KHR bit.
However, f61337b5 starts requesting front rendering usage bit when
EGL_MUTABLE_RENDER_BUFFER_BIT_KHR is seen on the SurfaceType, which
essentially forces linear usage on all winsys BOs for gallium dri and
i965 drivers on Android when cros gralloc is in use.
This patch dynamically appends or strips the front rendering usage bit
depends on whether EGL_RENDER_BUFFER is EGL_SINGLE_BUFFER or
EGL_BACK_BUFFER. The next dequeuBuffer call will switch the buffer
sharing mode while re-allocating winsys BOs given the updated gralloc
usage bits if necessary.

Define a version number for the interface GBM uses
to offload work to its backends/drivers. Store the
version in the backend interface structs provided
to the loader by backends, as well as in the core
interface struct provided to backends by the GBM
loader code to backends.
The backend can create structures of any version
it supports, which can be greater or less than the
interface version specified by GBM in the core
interface structure. Hence, GBM will need to take
care to check the backend version before accessing
any members added to structs defined in
gbm_backend_abi.h after this change.
Similarly, the backend may need to check the
interface version supported by the GBM library
before passing back data in any structure members
that require the GBM library to interact with
them for correct operation. For example, if for
some reason a structure defined in
gbm_backend_abi.h gained a field which was a
pointer to memory allocated by the backend and
freed by GBM, the backend should avoid allocating
this memory if the GBM library did not specify an
interface version new enough to indicate that it
was aware of the new structure member.

Android WSI api contract requires to allocate min_undequeued_buffers + 2
to achieve "triple buffering" effect, which is when the composer backend
acquired the allowed max numbder of buffers, the producer still has 2
buffers to rotate.
ANativeWindow either belongs to SurfaceView which presents directly to
SurfaceFlinger or belongs to other surfaces from the UI framework. For
the former, SurfaceFlinger hardcodes triple buffering for EGL. For the
latter, the surface caps decide the buffer limits or HWUI intercepts and
adjusts the min_undequeued_buffers to hint the EGL implementation to
prepare enough buffer cache slots while HWUI sets the max dequeued
buffer count accordingly.

Debugging fd mix-ups (ie. where, possibly via close()ing the original
fd, etc, you end up with something that is a valid fd but not a valid
*fence* fd) can be difficult. Fortunately we can use the FILE_INFO
ioctl, which will return an error if the fd is not a fence fd.
For android, we instead use the libsync API, which does a similar thing
on modern kernels, but has a fallback path for older android kernels.
Note that the FILE_INFO ioctl has existed upstream since at least prior
to destaging of sync_file.
