fcb22ecf0f
Adds a virtual method, GetFreshIds(), to Transformation. Every transformation uses this to indicate which ids in its protobuf message are fresh ids. This means that when replaying a sequence of transformations the replayer can obtain a smallest id that is not in use by the module already and that will not be used by any transformation by necessity. Ids greater than or equal to this id can be used as overflow ids. Fixes #3851.
