This is a lot of stuff, and sometimes quite wild, let's turn this into
its own header.
All stuff color-related that just generates sequences is now in
ansi-color.h (no .c file!), and everything more complex that
probes/ineracts with terminals remains in termina-util.[ch]

Cutting off in the middle may leave the terminal in a bad state, breaking
further output. But we don't know what a given ANSI sequence does, e.g.
ANSI_NORMAL should not be skipped. But it is also nice to keep various
sequences intact, so that if we had part of the string in blue, and we cut out
the beginning of the blue part, we still want to keep the remainder in color.
So let's just pass them through, stripping out the characters that take up
actual space.
Also, use memcpy_safe as we may end up copying zero bytes when ellipsizing at
the start/end of a string.
Fixes: #24502
This also fixes an ugliness where we would ellipsize string with ANSI
sequences too much, leading to output that was narrower on screen than the
requested length:
Starting AAAAAAAAAAAAAAAAAAAAA.service
Starting BBBBBBBBBBBBBBBBBBBBB.service
Starting LONG…ER.service

Recent gcc versions have started to trigger false positive
maybe-uninitialized warnings. Let's make sure we initialize
variables annotated with _cleanup_ to avoid these.

The name "def.h" originates from before the rule of "no needless abbreviations"
was established. Let's rename the file to clarify that it contains a collection
of various semi-related constants.

util.h is now about logarithms only, so we can rename it. Many files included
util.h for no apparent reason… Those includes are dropped.

Same idea as 03677889f0ef42cdc534bf3b31265a054b20a354.
No functional change intended. The type of the iterator is generally changed to
be 'const char*' instead of 'char*'. Despite the type commonly used, modifying
the string was not allowed.
I adjusted the naming of some short variables for clarity and reduced the scope
of some variable declarations in code that was being touched anyway.

This converts to TEST macro where it is trivial.
Some additional notable changes:
- simplify HAVE_LIBIDN #ifdef in test-dns-domain.c
- use saved_argc/saved_argv in test-copy.c, test-path-util.c,
test-tmpfiles.c and test-unit-file.c

Let's unify an beautify our remaining copyright statements, with a
unicode ©. This means our copyright statements are now always formatted
the same way. Yay.

This part of the copyright blurb stems from the GPL use recommendations:
https://www.gnu.org/licenses/gpl-howto.en.html
The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.
hence, let's just get rid of this old cruft, and shorten our codebase a
bit.

First, ellipsize() and ellipsize_mem() should not read past the input
buffer. Those functions take an explicit length for the input data, so they
should not assume that the buffer is terminated by a nul.
Second, ellipsization was off in various cases where wide on multi-byte
characters were used.
We had some basic test for ellipsize(), but apparently it wasn't enough to
catch more serious cases.
Should fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8686.

This primarily changes to things:
1. Ellipsation to 0, 1 or 2 characters is now supported. Previously we'd
hit an assert if the new lengths was < 3, this is now permitted. The
result strings won't show too much info still of course, but the code
becomes a bit more generic and robust to use.
2. If a UTF-8 mode is disabled and the input string is pure ASCII, then
"..." is used for ellipsation, otherwise (as before) "…". This means
on a pure-ASCII system we should remain pure-ASCII, matching
behaviour otherwise exposed with special_glyph() and friends. Note
that we'll use "…" for ellipsiation as soon as either the locale
settings indicate an UTF-8 mode or the input string already contains
non-ASCII unicode characters.
Testing for these special cases is improved.

Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

This follows what the kernel is doing, c.f.

This should be handled fine now by .dir-locals.el, so need to carry that
stuff in every file.

string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.
