Description

Re-organize Synchronized to allow synchronized(m) to work on:
1. std::mutex
2. std::recursive_mutex
3. std::atomic_flag

Move synchronized.hpp into stout, so that developers don't think it's part of the utility suite for actors in libprocess.

Remove references to internal.hpp and replace them with std::atomic_flag synchronization.
