Add per-Rollback synchronisation.

This adds a lock object to each Rollback that should be acquired before
accessing any rollback state.

For now, this synchronisation has been added 'in-place' in
RollbackManagerServiceImpl. Future changes will move rollback functionality
from that class into the Rollback class, which will allow the synchronisation
to be handled internally within the Rollback.
