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).

Fix descriptor/memory leak in compress(1) code

This is mostly a style fix since the code in question is not called multiple

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.

compress: Allow uncompress -c with multiple pathnames, as required by POSIX.

Per POSIX, allow passing multiple pathnames to uncompress -c, concatenating
the uncompressed data.

Passing multiple pathnames to compress -c remains disallowed, since the
result cannot be decompressed.

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.

Replace index() and rindex() calls with strchr() and strrchr().

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

Don't truncate the output file before making sure that we can
read at least 1 byte from the input file without problems. This
fixes a bug in uncompress(1) that causes the accidental removal
of files that happen to have the same name as the output file,
even when the uncompression fails and is aborted, i.e.:

$ echo hello world > hello
$ touch hello.Z
$ ls -l hello*
-rw-rw-r-- 1 giorgos giorgos 12 Jun 14 13:33 hello
-rw-rw-r-- 1 giorgos giorgos 0 Jun 14 13:33 hello.Z
$ ./uncompress -f hello
uncompress: hello.Z: Inappropriate file type or format
$ ls -l hello*
-rw-rw-r-- 1 giorgos giorgos 0 Jun 14 13:33 hello.Z
