Zbigniew Jędrzejewski-Szmek 04499a70fb Drop the text argument from assert_not_reached() 
In general we almost never hit those asserts in production code, so users see
them very rarely, if ever. But either way, we just need something that users
can pass to the developers.

We have quite a few of those asserts, and some have fairly nice messages, but
many are like "WTF?" or "???" or "unexpected something". The error that is
printed includes the file location, and function name. In almost all functions
there's at most one assert, so the function name alone is enough to identify
the failure for a developer. So we don't get much extra from the message, and
we might just as well drop them.

Dropping them makes our code a tiny bit smaller, and most importantly, improves
development experience by making it easy to insert such an assert in the code
without thinking how to phrase the argument.

Yu Watanabe 7f77917c0e sd-ipv4acd: update condition of address conflict 
See RFC 5227 section 2.1.1.

This introduces a callback which intend to a library user, e.g.
networkd, checks whether the sender hardware address is a MAC address of
the host's intrerface or not.

Yu Watanabe 38e980a6a5 sd-dhcp-client: tentatively ignore FORCERENEW command 
This makes DHCP client ignore FORCERENEW requests, as unauthenticated
FORCERENEW requests causes a security issue (TALOS-2020-1142, CVE-2020-13529).

Let's re-enable this after RFC3118 (Authentication for DHCP Messages)
and/or RFC6704 (Forcerenew Nonce Authentication) are implemented.

Fixes #16774.
