Botond Dénes 08bb0bd6aa mutation_fragment_stream_validator: wrap exceptions into own exception type ...

So a higher level component using the validator to validate a stream can
catch only validation errors, and let any other incidental exception
through.

This allows building data correctors on top of the
`mutation_fragment_stream_validator`, by filtering a fragment stream
through a validator, catching invalid fragment stream exceptions and
dropping the respective fragments from the stream.
