Commits on Feb 15, 2014

  1. std: add an RAII unlocker to Mutex. 

    This automatically unlocks its lock when it goes out of scope, and
provides a safe(ish) method to call .wait.

  3. std: Rename unstable::mutex::Mutex to StaticNativeMutex. 

    This better reflects its purpose and design.

  4. std: add a NativeMutex type as a wrapper to destroy StaticNativeMutex. 

    This obsoletes LittleLock, and so it is removed.

  5. sync: Add #[must_use] to the Mutex guard. 

    This helps people remember to save the return value to keep the mutex
locked as appropriate.
