4ba0dcaa42 event/dsw: sort events on dequeue
With this patch, the DSW event device will (optionally) sort the event
burst before giving it to the application. The sorting will primarily
be on queue id, and secondary on flow id.

The sorting is an attempt to optimize data and instruction cache usage
for the application, at the cost of additional event device overhead.

The DSW event device will now attempt to migrate (move) flows between
ports in order to balance the load.

2b7bc6a5b2 event/dsw: add port load measurements
The DSW event device port now attempts to estimate its load (i.e. how
busy it is). This is required for load balancing to work (although
load balancing is not included in this patch), and may also be useful
for debugging purposes.
