Terminology extended.

Updated.

Added.

As Thomas later suggested, I removed the reference for explicit mechanism.

Reworded. It now says: "There MUST be dedicated log entries for putting
and recovering an address from the declined state. They must include the
address, the client's details and the amount of time the address being
declined will remain in the declined state."

Both updated.
