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.

When the -p flag is specified, set an environment variable to the name
of the remote host (or rather, the name as mangled by realhostname_sa())
so that the process can use it to behave differently depending on the
origin on the request. We use this to implement rudimentary visibility
control on our user information.

Make sure that the child process's standard error goes through the same
NVT-ASCII filter as is applied to the standard output.

Don't attempt to call logerr() from the child since stdio is not safe in
a vforked process. Just write a message to fd 2 instead. (Ideally, the
parent would open two pipes, and siphon off our stderr to some place less
public, but I have not attempted to do so in this implementation.)
