Moved includes.chroot to includes.chroot_after_packages and added
includes.chroot_before_packages. includes.chroot does still work as before.
We also now use rsync for copying files if it is installed.
This improves runtime and space consumption for large includes.

Closes: #927128
it now covers:
- `lb chroot_apt install-binary`
- `lb chroot_archives {chroot|binary|source} {install|remove}`
by expanding usage from:
`lb chroot_prep {install|remove} HELPERS [ARGS]`
to:
`lb chroot_prep {install|remove} HELPERS [MODE[ MODE..]] [ARGS]`
where `[MODE[ MODE..]]` is an optional set of one or more of:
- archives-chroot, which specifies to use 'chroot' as the first param to
the chroot_archives script
- archives-binary, which specifies to use 'binary'
- archives-source, which specifies to use 'source'
- apt-install-binary, which specified to pass 'install-binary' instead of
'install' to chroot_apt
thus _all_ chroot prep scripts can be run through this helper now!
note, in the case of the binary stage, 'archives' is deliberately not added
to CHROOT_PREP_OTHER, this is not a mistake!

rather than explicitly running one helper after another in the major
build stages, or by hand (e.g. while testing things during development),
they can be run in bulk via this new helper. it essentially just takes a
list of helpers to run and runs them one by one.
it supports running all helpers except chroot_archives because that one
has different parameter requirements to the rest and supporting it would
make things messier.
helper scripts can either be named by their full script name or without
the 'chroot_' prefix for brevity. you can also just specify 'all' to
refer to all helpers (except chroot_archives, per above).
it automatically reverses the order of the list when run in remove mode.

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.
the cache restore/save script is not a chroot modification script unlike
the rest of the scripts that it was bunched up with. It is an actual
component part of the chroot build stage.
let's bring clarity to this with improved documentation.

Previously, we needed to keep the lb_* prefix as the scripts
could also be executed standalone. Since the lb wrapper is
mandatory since squeeze, we can drop this now.
Idea from Thomas Lange and FAI. Speedup in my testcase (standard image)
is 3m00 => 2m50, probably much better improvements for the desktop image
clients.
