Fix for issue 664: https://github.com/docker/distribution/issues/664

Browse Source 
Errors thrown by storage drivers don't have the name of the driver, causing user
confusion about whether the error is coming from Docker or from a storage driver.
This change adds the storage driver name to each error message.

This required changing ErrUnsupportedDriver to a type, leading to code changes
whenever ErrUnsupportedDriver is used.  The tests check whether the driver name
appears in the error message.
