comsat: Improve use of setuid()

Just return from jkfprintf if either (a) user lookup fails (that is,
getpwnam fails) or (b) setuid() to the user's uid fails. If comsat is
invoked from inetd using the default of tty:tty we will now return due
to setuid() failing rather than fopen() failing.

Remove copyright strings ifdef'd out

We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

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.

Port comsat to utmpx.

It seems comsat stats the utmpx database each 15 seconds to see whether
it has been changed. I am changing this behaviour to look at the utmpx
database upon processing. I don't want to allow direct interference with
the database files. I also wonder whether this optimization has any
measurable performance benefit nowadays.
