SERVER-17310 Replace boost::*_mutex::scoped_lock with boost::lock_guard.

Achieved via grep, sed and bash:
grep -Irl mutex::scoped_lock src/mongo | xargs sed -i.orig -E 's/(boost::(recursive_|timed_)?)mutex::scoped_lock/boost::lock_guard<\1mutex>/'

Then, by converting boost::lock_guard to boost::unique_lock as appropriate.

Finally, by removing unused mongo::mutex::try_lock.
