Make all copyright notices include this year.
Most say "2000-2026" but some files created later had later start
dates, and some created last year only had the start date. They now
all have "-2026" regardless.
Closes#340
A lot of scripts in this directory had "#!/usr/bin/perl" hard coded at
their tops. This is wrong, because perl may not be installed
there (it isn't on a lot of non-Linux systems). I have replaced the
hard-coded path with "/usr/bin/env perl" which will locate the perl
binary in the user's PATH.
Some scripts in this directory already had that. Those are scripts
that I actually use myself on a system that has perl in
/usr/local/bin, and so I had already fixed them.
Another alternative to using /usr/bin/env would be to create a
configure test to find the perl binary, then substitute it in a .in
version of the script. That is more work, for negligible benefit.
I have replaced all the "Copyright (C) .* The Xastir Group" lines in
the entire source tree with identical text, "Copyright (C) 2000-2018
The Xastir Group." By making every file have exactly the same text,
this simplifies the operation we have to perform in 2019 when we
update the copyrights.
I also found a few files with DOS-style CRLF line breaks. I have replaced
them with plain LF line breaks.
Also fixed a few "whitespace errors" in db2APRS.c
CVS keywords such as "$Id$" no longer serve any purpose now that we're
using git, and need to be removed. This commit removes all of the
"$Id$" keywords, and a few other CVS keywords of no current value.
I also had to change some lines of the scripts/lang*.pl files that were
looking for $Id$ tags in their input and replacing them with comments.
The entire intent of this was to add two lines of comments to the top of
the output, and now it just does that, instead of depending on the
presence of the $Id$ keyword.
