thus for some reason if one is connected to a tty and the other a file,
we still get colour in the tty by default.
in terms of options, --color and --no-color override both, no granular
ones added since it's not worth it imo.
this is backwards compatible with custom configs setting `_COLOR`.
it could be argued that setting $_COLOR to "false" for the auto non-tty
cases is redundant, which it is, but it doesn't hurt to do so; it ensures
that if anything (inc. 3rd-party hooks and such) rely on it that it
remains correct; and ensures that if anything in the future mistakenly
uses $_COLOR instead of $_COLOR_OUT|$_COLOR_ERR that at least that will
only be broken for the use case of only one of stdout|sdterr being a tty.

Current versions of the project files are built upon versions published
and licensed by Daniel Baumann, but are modified copies of those files and
thus need to be marked as such per licensing requirements (afaik he did
not pass along ownership / licensing rights to anyone when he left the
project). We should also be careful to not be misrepresenting such
modified copies as being attributed to Daniel.
Adding a new copyright line referring to "The Debian Live team" should
suffice for this.
The authorship block in man pages has also similarly been updated.
Notes:
- tweaked a copy of daniel copyright lines stating 2014 instead of 2015.
both of these cases were in files that i had personally introduced in
some of my past merged commits that moved some code around. i don't know
why they stated 2014.
- binary_onie was introduced in 2018, so that has a 2018 date instead of
2016 unlike the rest.
- 'efi-image' is a 3rd-party (Canonical Ltd) work that we bundle, but it
has been modified by 674794a8f4 and
36a3ba7634 so I similarly added a
debian live copyright line.
- 'grub-cpmodules' is similar. it was only changed by the indentation fix
of 36a3ba7634 but modification is
modification, and this does help cover any possible future changes that
might be made.
all scripts use `set -e` which means that if getop fails, the subsequent
error check that would print an error in addition to any printed by getopt
itself would never actually be reached.
the first though here would be to remove the pointless error check, but
getopt does not include the word "error" with an unrecognised option
failure, nor does it use colour to highlight problems, both of which mean
that it is a little lacking in terms of highlighting problems to users.
thus we properly capture and use the exit code here and output an
appropriate message per invalid argument vs getopt internal error.
also, removed the redundant stderr redirection which is already done
by Echo_error().
