RFC: Add write flag to reservation object fences

Hi everyone,

This set of patches tries to improve read after write hazard handling for reservation objects.

It allows us to specify for each shared fence if it represents a write operation.

Based on this the i915 driver is modified to always wait for all writes before pageflip and the previously used workaround is removed from amdgpu.

Please comment,
Christian.
