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).

lpr: remove a.out binary detection

Since the first unattributed commit in 1981, lpr has attempted to
prevent users from printing executables (and in earlier versions
archives). Archive detection was lost in 1992 when lpr gained a
dependency on a.out.h. No corresponding support was added for ELF files
with the full transiation to ELF in 1998, but a.out support has been
dragged forward to and contaminated platforms that never supported
a.out.

While this feature isn't unuseful, preventing the printing of
a single file format we stopped producing ~20 years ago isn't worth
the costs (however minimal).

spdx: initial adoption of licensing ID tags.

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.

Initially, only tag files that use BSD 4-Clause "Original" license.

Fix printing of files located on ZFS filesystem with an st_dev or
st_ino larger than 2**31.

From the PR:

Printing from a ZFS filesystem using 'lp' fails and returns an
email reporting "Your printer job was not printed because it was
not linked to the original file".

In order to protect against files being switched when files
are printed using 'lp' or 'lpr -s', the st_dev and st_ino
values for the original file are saved by lpr and verified
by lpd before the file is printed. Unfortunately, lpr prints
both values using '%d' (although both fields are unsigned)
and lpd(8) assumes a string of decimal digits.

ZFS (at least) generates st_dev values greater than 2^31-1,
resulting in negative values being printed - which lpd cannot
parse, leading it to report that the file has been switched.

A similar problem would occur with large inode numbers.

How-To-Repeat:

Find a file with either st_dev or st_ino greater than 2^31-1
(stat(1) will report both numbers) and print it with 'lpq -s'.
This should generate an email reporting that the file could
not be printed because it was not linked to the original file

This update gets it so 'lpr -r' ("remove the file after printing") will
try to move the file from the source to the destination (spool) directory.
If that succeeds, much time and disk-space will be saved by doing that
instead of copying the entire file only to remove the original. This
could be a big win on machines doing samba-service or CAP-based printing.

Note that this is about the fourth or fifth iteration of the patch, after
trying to address all possible security implications of the change.

Submitted by: "Steve O'Hara-Smith" <steveo@eircom.net>

Allow those of us who have to print through LPRng spoolers to send
spooler options using `Z' control-file lines and the `-Z' flag.

It's not been possible to configure a print server running lpd,
with remote hosts feeding it, so that some hosts have their header
pages supressed and some don't. This is because lpd doesn't know
how to rewrite a print job before forwarding it to a remote lpd.
In particular this causes problems with p rinters that contain
their own lpd, eg. HP jet direct cards, because they can't suppress
headers. It's not possible to have headers supressed by putting
'sh' in any printcap in the lpd chain, it is up to the originating
lpr to have a '-h' option specified at run time.

Lpr has been modified to allow _it_ to honour the 'sh' flag in the
local print cap. This allows the administrator to switch off
headers for a particular printer (on a particular host) irrespective
of whether that printer is local to the machine or remote.

This doesn't break anything, because in the case of a remote printer
the 'sh' flag would have had no meaning, in the case of the local
printer it would have been on anyway.

- Give each capability a human-readable name in addition to the historic

- Otherwise generally clean up a lot of dark corners. Many still remain.

Convert the option parser to use getopt(3). This makes it more
orthogonal with the rest of the system (you can now use either -PPS or
-P PS), and makes the parser more intelligible. The only drawback is
that the old semantics for the -i flag in case a non-numeric argument
is following are no longer fully supported (only if -i is the very
last arg at all), since getopt(3) doesn't support the discticnction
between numeric and non-numeric arguments.

Make lpr also understand dashes as input pseudo filenames. This
finally makes lp(1) fully comply with Posix.2.
