Android syncpoints can be mapped to a timeline. This removes the need
to maintain a separate api for synchronization. I've left the android
trace events in place, but the core fence events should already be
sufficient for debugging.

The following series implements fence and converts dma-buf and
android sync to use it. Patch 5 and 6 add support for polling
to dma-buf, blocking until all fences are signaled.
Patch 7 and 8 provide some helpers, and allow use of RCU in the
reservation api. The helpers make it easier to convert
Move the list of shared fences to a struct, and return it in
reservation_object_get_list().
Add reservation_object_get_excl to get the exclusive fence.
Add reservation_object_reserve_shared(), which reserves space
in the reservation_object for 1 more shared fence.
This adds 4 more functions to deal with rcu.
reservation_object_get_fences_rcu() will obtain the list of shared
and exclusive fences without obtaining the ww_mutex.
reservation_object_wait_timeout_rcu() will wait on all fences of the
reservation_object, without obtaining the ww_mutex.
A fence can be attached to a buffer which is being filled or consumed
by hw, to allow userspace to pass the buffer without waiting to another
device. For example, userspace can call page_flip ioctl to display the
next frame of graphics after kicking the GPU but while the GPU is still
rendering.
This allows reservation objects to be used in dma-buf. it's required
for implementing polling support on the fences that belong to a dma-buf.

Doesn't this produce compiler warnings since the static v4l2_of_parse_*

Those functions are inside the #if 0, so the compiler never sees them.
