dhclient: add ability to ignore options in offers

A machine might exist on multiple networks, all of which offer, say, default
routes or name servers. There's no easy way to indicate in the config
that those options are only valid for a single interface.

Now, we can write:

interface "lan0" {
request routers;
require routers;
}
interface "lan1" {
ignore routers;
}

And only take action on default routes offered on lan0.

dhclient: raise WARNS to 4

Mostly const-correctness fixes. There were also some variable-shadowing,
unused variable, and a couple of sockaddr type-correctness changes. I also had
trouble with cast-align warnings. I was able to prove that one of them was a
false positive. But ultimately I had to disable the warning program-wide to
deal with the others.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
