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).

Remove extraneous setutxent() calls in write(1).

We already call setutxent() once during initialization. Furthermore,
the subsequent calls occur after the process has entered capability
mode, so they fail, and attempts to fetch database entries fail as
a result.

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.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

write(1): Capsicumify

Enter Capsicum capability sandbox pretty early in this setuid program.

Some minor modifications were needed to cache directory fds and use
relative lookups.

Rights restriction of the stdio descriptors is unfortunately pretty messy
because we need an ioctl capability not present in the current libcapsicum
helpers (FIODGNAME).

write(1) needs to strip off the leading /dev/ from the tty name for the
current tty as returned from ttyname(3) so it can try to avoid writing to
the current tty if possible. Previously, it did this by trimming off any
leading directory (effectively performing a basename(3) on the path
returned from ttyname(3)). However, this chopped off too much of the path
for ttys who have directories in their name such as pts(4). Instead, just
strip off the leading /dev/ from the path returned by ttyname(3). This
fixes write(1) when using pts(4).
