Add initial implementation of threads/mutexes/semaphores/cvs/spinlocks

Browse Source 
Added initial implementation (or wrapper) of the threading library.
It's rather basic, but should work for most of the tasks.

Unfortunately, spinlock implementation relies on GCC/Clang compiler
built-ins (or in-worst-case-scenario on Win32 - InterlockExchange).
In the future, I should revisit this code and fix/reimplement some stuff
(or add support for Windows XP).
