backends: Split out CRTC/output management to MetaGpu In order to eventually support multilpe GPUs with their own connectors, split out related meta data management (i.e. outputs, CRTCs and CRTC modes) into a new MetaGpu GObject. The Xrandr backend always assumes there is always only a single "GPU" as the GPU is abstracted by the X server; only the native backend (aside from the test backend) will eventually see more than one GPU. The Xrandr backend still moves some management to MetaGpuXrandr, in order to behave more similarly to the KMS counterparts. https://bugzilla.gnome.org/show_bug.cgi?id=785381

renderer/native: Also wrap flip closures for EGLStreams When using the EGLStream backend, the MetaRendererNative passed a GClosure to KMS when using EGLStreams, but KMS flip callback event handler in meta-gpu-kms.c expected a closure wrapped in a closure container, meaning it'd instead crash when using EGLStreams.

renderer/native: Retry page flip after one vsync if EBUSY We might fail to page flip a new buffer, often after resuming, due to the FIFO being full. Prior to this commit, we handled this by switching over to plain mode setting instead of page flipping. This is bad because we won't be synchronized to the refresh rate anymore, but just the clock. Instead, deal with this by trying again until the FIFO is no longer full. Do this on a v-sync based interval, until it works. This also changes the error handling code for drivers not supporting page flipping to rely on them returning -EINVAL. The handling is moved from pretending a page flip working to explicit mode setting in meta-renderer-native.c. Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/460

renderer-native: Add hardware presentation timing Add support for getting hardware presentation times from KMS (Wayland sessions). Also implement cogl_get_clock_time which is required to compare and judge the age of presentation timestamps. For single monitor systems this is straightforward. For multi-monitor systems though we have to choose a display to sync to. The compositor already partially solves this for us in the case of only one display updating because it will only use the subset of monitors that are changing. In the case of multiple monitors consuming the same frame concurrently however, we choose the fastest one (in use at the time). Note however that we also need !73 to land in order to fully realize multiple monitors running at full speed.
