From: Xiao Guangrong <xiaoguangrong@tencent.com>

Changelog in v3:
Thanks to Emilio's comments and his example code, the changes in
this version are:
1. move @requests from the shared data struct to each single thread
2. move completion ev from the shared data struct to each single thread
3. move bitmaps from the shared data struct to each single thread
4. limit the number of request that each thread need handle to 64, then
   use uint64_t instead of bitmap pointer.
   
The performance is measured by using the benchmark we introduced in
this pachset:
	./tests/threaded-workqueue-bench -c 20 -m 16 -t N
the data is as followings:
