Execution dependency management.

Can attach buffers to executions that will only be unref'd once the buffer has finished executing. Adding a frame dep will lock the frame, until either the dependencies are discarded, the execution is submitted, or a failure happens. update_frame will update the frame's properties before it is unlocked, only if submission was successful.
