Required to eventually support DRM colour management APIs, and to
support Volta.

When only the position of a window changes, there's no need to submit
an image update as well.

Will be required to support the overlays, and Volta windows.

Window visibility is going to become a little more complicated with the
upcoming LUT changes, so store the calculated value to avoid needing to
recalculate the armed state again.

This is just cleaning up some left-overs from when we needed a custom
legacy page flip implementation.

Instead of windows returning their core channel interlock mask if they
know core has been modified, it's recorded unconditionally and used if
required when update methods are emitted.

This will be required to support Volta.

GV100 doesn't support MST, use the information provided in VBIOS tables to

Fences attached to deferred client work items now originate from channels
belonging to the client, meaning we can be certain they've been signalled
before we destroy a client.

This closes a race that could happen if the dma_fence_wait_timeout() call
didn't succeed.  When the fence was later signalled, a use-after-free was
possible.

As VMAs are per-client, unlike buffers, this allows us to avoid referencing
foreign fences (those that belong to another client/driver) from the client
deferred work handler, and prevent some not-fun race conditions that can be
triggered when a fence stalls.
