Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Avoid using single quotes in arguments to logger.

Single quotes interfere with the workaround put in with r335753 and
aren't necessary in this case. I believe that all the underling issues
with r335753 have been corrected, but need to do more extensive
followup before reverting it as a bad idea.

Add missing "ereport." prefixes of ZFS events.

I was unable to find time when those were working. I think they have been
broken for at least 5 years or even longer.

MFC after: 1 month

Move all devd related configs to sbin/devd/

This helps with pkgbase as it switches these to using CONFS so they are
properly tagged as config files.
