* move concurrency primitives that always operate on kernel threads to the std.Thread namespace * remove std.SpinLock. Nobody should use this in a non-freestanding environment; the other primitives are always preferable. In freestanding, it will be necessary to put custom spin logic in there, so there are no use cases for a std lib version. * move some std lib files to the top level fields convention * add std.Thread.spinLoopHint * add std.Thread.Condition * add std.Thread.Semaphore * new implementation of std.Thread.Mutex for Windows and non-pthreads Linux * add std.Thread.RwLock Implementations provided by @kprotty
