Async synchronization primitives.

This crate provides the following primitives:

• Barrier - enables tasks to synchronize all together at the same time.
• Mutex - a mutual exclusion lock.
• RwLock - a reader-writer lock, allowing any number of readers or a single writer.
• Semaphore - limits the number of concurrent operations.
