Following a similar approach as with buffer object handles, and for the very same reason of not being able to request a specific handle when creating contexts, use the newly added AMDGPU_CTX_OP_CHANGE_HANDLE operation supported by the DRM_IOCTL_AMDGPU_CTX ioctl so we can re-create the context handles as they were in the original process. Before this change we could only restore a trivial userspace which only created and never closed any contexts, but now we can handle "sparse" namespaces as well.
