Create sync_file->fence to abstract the type of fence we are using for each sync_file. If only one fence is present we use a normal struct fence but if there is more fences to be added to the sync_file a fence_array is created. This change cleans up sync_file a bit. We don't need to have sync_file_cb array anymore. Instead, as we always have one fence, only one fence callback is registered per sync_file. v2: Comments from Chris Wilson and Christian König - Not using fence_ops anymore - fence_is_array() was created to differentiate fence from fence_array - fence_array_teardown() is now exported and used under fence_is_array() - struct sync_file lost num_fences member v3: Comments from Chris Wilson and Christian König - struct sync_file lost status member in favor of fence_is_signaled() - drop use of fence_array_teardown() - use sizeof(*fence) to allocate only an array on fence pointers v4: Comments from Chris Wilson - use sizeof(*fence) to reallocate array - fix typo in comments - protect num_fences sum against overflows - use array->base instead of casting the to struct fence v5: fixes checkpatch warnings v6: fix case where all fences are signaled.
