The semantics were significantly changed inc779a44222("hostnamed: Fix the way that static and transient host names interact", Feb. 2014), but when the dbus api documentation was imported much later, it wasn't properly adjusted to describe those new semantics.34293dfafdwhich added systemd.hostname= also added new behaviour. Let's ove various bits and pieces around so that they are in more appropriate places. Drop recommendations to set the hostname for DHCP or mDNS purposes. Nowadays we expect tools that want to expose some different hostname to the outside to manage that internally without affecting visible state. Also drop mentions of DHCP or mDNS directly setting the hostname, since nowadays network management software is expected to (and does) go through hostnamed. Also, add a high-level description of semantics. It glosses over the details of handling of localhost-style names. Later commits will remove this special handling anyway.
