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 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.

Discussed with: imp, rwatson
Unfortunately it also uses lastlog, which means we must resort to local
extensions of the utmpx-interface. Because the user name and TTY name
are now nul-terminated, there is no need to copy around strings as
often.
included twice by lprint.c, which included both finger.h and extern.h.
finger.h, in turn, includes extern.h. The redundant include of extern.h
was removed from lprint.c, as part of this change, but the include guards
were added anyway out of spite.
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.
