Compositor: Implement linux-dmabuf-unstable-v1
[ChangeLog][Compositor] Added support for linux-dmabuf-unstable-v1.
Implement client side DMABUF buffer sharing support by supporting the
linux-dmabuf-unstable-v1 (version 3) protocol. For enabling DMABUF,
set the following environment variables for the compositor:
QT_QPA_PLATFORM=eglfs
QT_WAYLAND_CLIENT_BUFFER_INTEGRATION=linux-dmabuf-unstable-v1
The current implementation supports the following DRM buffer formats:
- RGB and RGBA
- YUYV
This implementation requires Mesa with the following patch applied.
Otherwise, textures are not updated. The patch is contained in Mesa 18.1.5.
See https://patchwork.freedesktop.org/patch/238080/
Fixes: QTBUG-66288
Fixes: QTBUG-67845
