Remove locking from ClutterTimeoutPool

Browse Source 
The mutex protection for the timeout pool was causing deadlocks, so it has been
removed for the time being, until I figure out a way to make it work properly.
A timeout pool should not be considered thread-safe (or thread-aware) until further
notice.
