The reserved non-terminals and are a bit inconvenient in the implementation of algorithms. By replacing them with reserved terminals, the rtg language will be a bit cleaner.

STR-676, martin:
The new format checker now supports this.

Todo: update sdf2rtg.

This requires some bootstrapping (the old format-checker needs to be gone first)

STR-676, martin:
sdf2rtg will not be changed for a while to keep the old format checker working.

For new tools, a simple upgrade traversal is sufficient.
