Josh Triplett fb1ad2fe02 Improve documentation for file locking
Add notes to each method stating that locks get dropped on close.

Clarify the return values of the try methods: they're only defined if
the lock is held via a *different* file handle/descriptor. That goes
along with the documentation that calling them while holding a lock via
the *same* file handle/descriptor may deadlock.

Document the behavior of unlock if no lock is held.
