Bug#14549809 LINKING PROBLEM IN 5.5.28 BUILDS WITH THREADPOOL PLUGIN

The use of Thread_iterator did not work on windows (linking problems).
Solution: Change the interface between the thread_pool and the server
to only use simple free functions.

This patch is for 5.5 only (mimicks similar solution in 5.6)
