The divert structure was using the port number to indicate that
divert-to or divert-reply was active.  If the address was also set,
it meant divert-to.  Divert packet used a separate structure.  This
is confusing and makes it hard to add new features.  It is better
to have a divert type that explicitly says what is configured.
Convert the pfctl(8) rule parser to divert types, kernel cleanup
will be the next step.
