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.

it was not run in install mode so should not be run in remove mode.
(whether it should in fact be run in install mode is another question; as
is whether chroot_tmpfs should be being used)

when used alongside syslinux and when a single kernel flavour is used,
things work correctly. otherwise booting from EFI is broken.
the problem comes from the fact that syslinux, for a single kernel flavour
creates the file /live/vmlinuz, which is used by the minimal EFI grub.cfg
to locate the device and partition containing the live image. when multiple
kernel flavours are used, it instead creates /live/vmlinuz1, /live/vmlinuz2,
etc. which thus is a problem. similarly when syslinux is not used, you are
left only with long filenames for the kernel files, for example
/live/vmlinuz-4.19.0-8-amd64. in these situations grub cannot find the
device containing the image and thus fails to display the boot menu.
the solution here, instead of dynamically changing the filename searched
for depending upon bootloader configuration, switches to doing a search for
the file /.disk/info instead. this file is generated by binary_disk, and
is present for iso, iso-hybrid and hdd images types, though grub-efi cannot
be used for the hdd type. it is not created for the netboot type, but again,
grub-efi is not compatible with that anyway. it is not created for the tar
type, which the grub-efi script does not block as incompatible, but is this
not a mistake?
furthermore, switching to searching for /.disk/info helps avoid issues for
systems that happen to actually include a real /live/vmlinuz path other
than on a removable live disk or CD/DVD, as is the case with a HP system
discussed in #924053.
this patch was written by adrian15sgd@gmail.com, as per the authorship,
who attached it to the #924053 bug discussion. this commit message however
has been re-written by jnqnfe@gmail.com, prior to submission via an MR,
as part of the fix towards the issues reported in #956131.

Closes: #924053
backwards compatibility:
1. the new file will be included alongside any user custom config
2. rather than replace MEMTEST with an actual config entry, we replace it
with a line to import the content of the new file, and thus will work
just as before.
thus no backwards compatible breakage
Gbp-Dch: Short
backwards compatibility:
1. the new install.cfg and install_start.cfg files (chosen
automatically from the install_*gui.cfg and install_*test.cfg
files) will be included alongside any user custom config.
2. the placeholders are now replaced with lines importing these files
thus everything will work just as before, i.e. no backwards
compatibility breakage.

as just done for grub2|loopback
the primary benefit here is that it means that user configs do not
have to carry copies of all files; they just carry the ones they
want to replace (or add).
Gbp-Dch: Short
`$_SOURCE` is always composed of `<foo>/${_BOOTLOADER}`, so we can just use
`${_BOOTLOADER}` as the basename, without calling `basename ${_SOURCE}`
Gbp-Dch: Ignore
...rather than choosing between the default set and a user provided set
1. ensures backwards compatibility after we switch from generation of
certain content to that content being in pre-prepared config files,
and thus no longer writing that config out to existing files.
2. means that user configs do not have to carry copies of all files; they
just carry the ones they want to replace (or add).

this takes a step forward in moving towards the same updated layout as
with syslinux; here we get:
- <live entries>
- Start installer
- Advanced install options...
- <full set of install options>
- Advanced options...
- Memory Diagnostic Tool (memtest86[+])
note that this only affects the default menu. custom configs are not
affected by this change.
further steps to complete the move to the updated layout will follow
later.
"Advanced options..." should perhaps be renamed later.
Gbp-Dch: Short
an official current debian install disc was compared with to achieve
better consistency.
main menu:
- i: for the single "start" entry
advanced submenu:
- g: for the main graphical entry
- i: for the main text-based entry
- x: for the main expert entry
- a: for the main auto entry
- r: for the main rescue entry
- s: for the synth entry
for expert, auto and rescue, the hotkey is given to the graphical entry
where present, otherwise to the text entry.
Gbp-Dch: Short
...for consistency with syslinux config placeholders and improved
clarity of what text is a placeholder.
the old placeholders without the bookends are still replaced for
user configs for backwards compatibility.
the new ones are little used just at the moment but are expected to
become used much more in later commits.
Gbp-Dch: Short
d-i removed this in commit 0917b2dde3ff73a204d27dd2f2fffc8a41175ddd
Note: There was inconsistency between grub and syslinux in use of this, with
syslinux not having it on graphical rescue and auto modes while grub entries
did. The patch to fix that has been dropped since we're removing it everywhere
anyway.

progress-linux, as discussed in MR #142 ([1]) is a little known distro,
which appears to be little more than a personal project of the original
author of live-build.
given that, the expense of maintaining all of these old hacks for it
cannot be justified. it is not known whether or not live-build is even
used with respect to it since the author abandoned live-build some
years ago.
also, at least one past change in live-build possibly broke progress-linux
compatibility anyway, which would have required progress-linux users of
live-build to use a custom progress-linux config, or a progress-linux
fork of live-build, and there is no knowing how much of the hacks in this
"upstream" codebase any user of progress-linux currently relies upon.
and again, progress-linux appears to just be a personal project of
Daniel's, with afaik very little userbase. (Daniel seems to be the only
developer working on the project which speaks to how small it is).

when the --fdisk and --losetup options were removed, the entries in the
getopt option list should have remained for backwards compatibility such
that the usage warnings can kick in instead of unknown option errors.

this function takes one or more required stage fileS _plural_, and exits
if any are missing (or at least it does now after the refactor).
let's rename it to make things more clear
Gbp-Dch: Short
as suggested by Raphaël
rather than have fixed stagefile filename strings at all in the scripts,
use `$(basename $0)` to use the name of the script (which is the same for
almost all cases anyway, and the stage files are supposed to be almost
exclusively unique per-script). we can thus simplify things by determining
the filename for most use cases within the functions themselves.
this does change the file used by a couple of scripts, affecting backwards
compatibility of executing live-build upon an existing partially or fully
completed build:
- binary_grub-pc used "binary_grub"
- chroot_includes used "includes.chroot"
care had to be taken for the following cases:
- there are some cases like bootstrap_cache, source_debian and
bootstrap_debootstrap which are dealing with more than one file, and/or
otherwise a filename that is not specific to the script itself exactly,
or should not be based upon its name.
- some cases like chroot_cache, bootstrap_cache and
chroot_install-packages need to append something to the end of the name
depending upon which pass/action mode the script is being executed with.
- furthermore in the bootstrap_cache case one of the filenames is used
within the bootstrap_debootstrap and thus needs very careful handling
to be certain that a change in filename of bootstrap_cache does not
break bootstrap_debootstrap.
Gbp-Dch: Short
- avoid all need to pass ".build/" path in stage file names into the
functions
- add a helper to remove a stage file (required to complete the above
properly)
- avoid duplicating filenames within scripts which makes them prone to
mistakes (some instances of which I've actually encountered and had
to fix)
Gbp-Dch: Short
Fixes the following
- Correct version (memtest86/memtest86+) shown instead of fixed 'memtest86+' text
- Ensure correct directory path always used by using replaceable placeholder
Gbp-Dch: Short
all vars affected have been carefully checked to be quite certain
that they are definitely local
where variable is assigned the return value of a function/command, the
local "declaration" is deliberately done on a separate line, since
`local FOO` is actually treated itself as a command rather than a
declaration; will thus always cause $? to be zero, and thus if done on
the same line as such an assignment can not only clobber $? but in doing
so unintentionally blocks failure of a command from triggering the
expected exit from having `set -e`.
also, from testing, i have found that when assigning "${@}" this must be
done on a separate line confusingly as otherwise an error occurs.
