WT-2816 General improvements to WiredTiger eviction performance (#2949)
A set of changes to the eviction algorithm including:
* Fix a bug in how many items can be added to the urgent queue
* Have the eviction server sleep less so it recovers from disruptions faster.
* Only have application threads evict dirty pages if they are blocked on the dirty trigger.
* Swap eviction queues when one becomes empty.
* Have the eviction server populate the "other" queue whenever it notices that it isn't full.
