So the "rodata=on" is the default.
But the current code does not follow the document, it makes "rodata=full"
as the default.
This patch set follows Will's suggetions:
- Make our "on" behaviour be what is currently done by "full"
- Remove RODATA_FULL_DEFAULT_ENABLED
- Introduce a new option (e.g. "rodata=noalias") which would match the
current "on" behaviour
- Update (simplify) the documentation

Follows Will's suggetions.
