Move the functionality for the following components to the new base support library: - BoundMethod - EventDispatcher - EventDispatcherPoll - Log - Message - Object - Signal - Semaphore - Thread - Timer While it would be preferable to see these split to move one component per commit, these components are all interdependent upon each other, which leaves us with one big change performing the move for all of them.
