Change subject: Change select hook interface and select_sync_pool API
......................................................................
Change select hook interface and select_sync_pool API
* The select hooks are now called once per selection with the entire set
of events to select, instead of once for every individual event.
* The hooks now also return any events already present directly.
* select_sync_pools are no longer allocated dynamically but are
initialized at device/object creation time.
* select_sync_pools are associated with a mutex which allows the select
code to deselect entries without making a call to the device.
* Pool entries are no longer dynamically allocated. The select_info
itself is added to the pool. This means that select_infos cannot be
added to multiple pools.
* The deselect device hook is no longer called.

Cherry-picked from hamishm's "event_queue" branch. Changes by me:
* De-bitrot. There was a minor refactor of some of the wait_for_objects
code and so this needed appropriate tweaking.
* Remove some of the deprecated methods which were not used;
fewer compatibility shims to provide.
