ad01e102a8 Re-entrant distributed locks with ping unlock retries -- SERVER-3024 
Retries unlock when process is still up but config server has gone down,
in case of errors during locking and unlocking.  Also allows testing
of locks already held.

fbef3e1b63 fix for distlock (fixes sync5, sync6 failures) 
unlocking can unsafely unset new locks if set during unlock process, this patch ensures new locks are not able to be forced -after- checking individual lock documents

737a20b8fa Fixes for distributed lock handling time skew. 
In general, the current distributed lock is susceptible to time skew in config servers and mongos clients.  This update
uses an algorithm that checks for time skew, as well as providing some more robust tests to make sure a distributed
lock cannot be forced prematurely.  Some documentation on the website, currently hidden from non-10gen, gives more
info.
