running `lb config --validate` causes the script to stop after running
the validation check on the config compiled at that point, prior to
writing the config to disk.
this gives users the ability to check the validity of a config without
modifying or rewriting the saved config.
note that if users provide new config options alongside --validate, these
are taken into account in the check performed.
the 'check complete' message will not be seen if an error is reported by
the check function, while it will be seen if only warnings are given, but
it would require a redesign of the validation check function to make any
improvement in that area, and it's perhaps not worth it.

it mostly applies defaults where a value does not exist, but does more in
some cases. the new name better reflects its usage and functionality.

this is used after applying user settings on top of the defaults,
so is not specific to checking defaults; it's a validation checker.

whilst some parts of the codebase were set up to work with multiple types
specified, others did not work with it and would not necessarily be easy
to adjust. this thus makes some tweaks to adjust things accordingly.
- option renamed to singular form (maintaining backwards compatibility)
- a validation check has been added
- unnecessary glob style type references fixed
- checks with In_list changed to a direct singular comparison
- typo of type "netboot" written as just "net" fixed (though unreachable
so of no consequence; really the code could be removed but it's trivial)

two parts of the code worked with both comma and space separated lists,
while two others only worked with comma separated.
swapping out commas with spaces when we setup the var in
Set_config_defaults() means that individual scripts no longer need to worry
about it and everything supports both; and that we can avoid the
IFS/OLDIFS mess.

to protect against simple mistake of using 'all' instead of
'all-except-archives' when manually executing scripts (e.g. during
development) at the bootstrap stage level. (the bootstrap stage does not
and should not use the archives helper).

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.

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.

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

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

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).

`$_SOURCE` is always composed of `<foo>/${_BOOTLOADER}`, so we can just use
`${_BOOTLOADER}` as the basename, without calling `basename ${_SOURCE}`

...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.

make it consistent with syslinux
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.

...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.

fixes an error I experienced in a test build
Gbp-Dch: Short

...from the `Set_config_defaults` function, to being done directly
in `build.sh` (the component which is also responsible for loading
functions, loaded at the start of every script, including the front
end).
thus the colouring decision will now correctly...
- apply to the frontend, such as to the 'root privileges needed'
error, the 'no such script' error, and the command name
colouring that I want to add (the most significant issue).
- apply to error messages generated by the `Arguments` and
`Read_conffiles` functions, which are called before
`Set_config_defaults` by scripts.
as things were, due to the comparison with "false", colour would
_always_ be used in these places (unless _COLOR_ERR=false or
_COLOR_OUT=false wrt. the new command highlight, were set in the
environment when executing a script throught the frontend).
this would not be a problem for normal terminal use of course,
besides being inconsistent where color were turned off, but would
be a bit of a problem if redirected to a file.
a re-evaluation of _COLOR is performed in `Set_config_defaults` to
adjust _COLOR_OUT and _COLOR_ERR where necessary, to correctly
respond to _COLOR being set in saved config files (disabled by
default but a user could always enable), after the point of config
files being loaded.
_COLOR can still be controlled from the environment just as before,
overriding both _COLOR_OUT and _COLOR_ERR.
note that this does not address the fact that --color|--no-color
do not work in the frontend and thus will not impact the colouring
of to-be-introduced command highlighting. this needs to be
addressed separately.

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.
