  netlink-socket.c: event polling for packets on windows

Currently, we do busy-polling for packets on Windows. In this patch
we nuke that code and schedule an event.

The code has been tested for packet reads, and CPU utilization of
ovs-vswitchd went down drastically.

I'll send out the changes to get vport events to work in a seperate
patch.
