Set trigger functions are implemented, TCP/UDP change trigger functions are missing.

Also, for automatic MDNS integration, we would need a new netif change callback type where multiple clients can be registered so the mdns code can register itself and does not have to be called from a user's netif status callback function.

That new callback type could include a hint on what's changed (i.e. why was the callback called).

Trigger is needed to write meaningful applications. e.g. MDNS does not correctly announce IPv6 address without this trigger..

A little clarification of what's to do:
- change IPv6 address(es/state) via a function, not via inline code
- make that function call into netif.c to implement the address changed triggers

Like for IPv4, we need to:
- close TCP functions open on removed addresses
- possibly report MLD groups?
- possibly start router solicitation?
- call netif status callback

I saw that the initial router solicitations seem to be dropped as the rs messages are not sent because the ll address is still tentative...
