Roman Sudarikov c3bc40a6ef io_channel: add return value to pollers 
This will be used to track time used in pollers - each poller can now
indicate if it found any work to do or not.

For cases where it was obvious and the infrastructure was already in
place, existing pollers have been modified to return 0 or a positive
value to indicate whether work was done.  Other pollers have been
modified to return -1 by default, indicating that the poller isn't
indicating anything about whether work was performed.  This will allow
us to find un-annotated pollers easily in the future and fix them
incrementally.
