Added a basic integrity checker, and some basic ability to recover from store

corruption, rather than just spewing error messages and exiting.

Added a xenstore-control executable, which sends commands to xenstored.
Currently, the only command is 'check', which triggers an integrity check.
(The integrity check is also triggered whenever a corrupted store is detected).
