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 Change-Id: Id4d90337dbe0be956b0f964426ebed3f281c6c30 Reviewed-by: Johan Helsing <johan.helsing@qt.io>
