3 of 4 commit (sorry my svn clinet is crazy for moment)

Commit w3seek patch from bug 1609 : file attachment (id=910) 
The attached patch implements QueueUserWorkItem()/RtlQueueWorkItem() (lacks
optimizations!!!). WINE's latest rpcrt4 relies on it.

1. Implement QueueUserWorkItem()/RtlQueueWorkItem() :
2. A slightly optimized 
3. Supports WT_TRANSFER_IMPERSONATION
4. Slightly improved handling of growing/shrinking the pool by assuming work items with WT_EXECUTELONGFUNCTION run longer
5. Fixes a hack that made a worker thread always terminate if there were at least one more thread available
