     Allow the GHCi messages to be overridden via the GHC API; fixes #7456

     They now go through log_action. The existing severities all used
     printDoc, which always adds a trailing newline, which we don't
     want for the GHCi messages. I therefore added a new severity
     SevInteractive, which doesn't add a newline.
