Subject: Addressing #6082 and #7766 (overriding format of notation).

We do two changes:
- We distinguish between a notion of format generically attached to
  notations and a new notion of format attached to interpreted
  notations. "Reserved Notation" attaches a format
  generically. "Notation" attaches the format specifically to the given
  interpretation, and additionally, attaches it generically if it is the
  first time the notation is defined.
- We warn before overriding an explicitly reserved generic format, or
  a specific format.
