Erik Gilling 43d2228223 sync: refactor sync debug printing 
Move driver callbacks to fill strings instead of using seq_files.  This
will allow those values to be used in a future tracepoint patch.

Erik Gilling 8c9daff58d sync: add reference counting to timelines 
If a timeline is destroyed while fences still hold pts on it, the reworked
fence release handler can cause the timeline to be freed before all it's points
are freed.

compilation failure.

Erik Gilling 220411fe58 sync: add internal refcounting to fences 
If a fence is released while a timeline that one of it's pts is on is being
signaled, it is possible for that fence to be deleted before it is signaled.
This patch adds a refcount for internal references such as signaled pt
processing.

Erik Gilling c80114fd8b sync: allow async waits to be canceled 
In order to allow drivers to cleanly handled teardown we need to allow them
to cancel pending async waits.  To do this cleanly, we move allocation of
sync_fence_waiter to the driver calling sync_async_wait().
