Fixes the following
- Correct version (memtest86/memtest86+) shown instead of fixed 'memtest86+' text
- Ensure correct directory path always used by using replaceable placeholder

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.

The '---' delimiter should appear before the final 'quiet' parameter
(which is used by the debian installer I believe).
This delimiter is added by live-build in syslinux configs, and is present
in both grub2 and syslinux configs in an official debian 7.7 disc image,
suggesting strongly that live-build grub/grub2 menu creation code is in
the wrong here by missing it.
update: this commit previously used -- as was correct at the time, and has
since been updated to use --- per #775128; which was previously tackled in
a separate later commit. the switch to --- was already done for syslinux
(which was not missing the delimiter unlike grub) in

I believe that the `quiet` parameter is meant for d-i not the kernel and
thus should be given on the end after a delimiter, as done with syslinux.
Here we switch the order to move it to the end. The addition of the missing
delimiter will be done in a followup commit.

Current splash makes it very difficult to read menu entries.
Black as a background color is actually interpreted as transparent,
so switching to something else so the highlighted menu entry can be
read more easily.
Gbp-Dch: Short
When building grub2 menu entries the quiet param (meant for d-i)
was excluded from the rescue menu entries instead of expert.
This is the opposite to what is done in the following:
- Menu entries seen in official debian 7.7 disc images (grub2 and syslinux configs)
- Menu entries created for grub (legacy)
- Menu entries created for syslinux
The evidence strongly suggests that the grub2 menu creation was in the wrong!

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.
Gbp-Dch: Ignore
...when stdout+stderr connected to a tty (as opposed for example to being
piped to a log file)
very helpful to have colour such that the red/yellow of errors/warnings
can draw the eye to problems.

`DI_PACKAGES` does not need to include `DI_REQ_PACKAGES` so long as
we pass the latter to apt in the one case where it was not already
being given it.
in fact with it including that sub-list meant that in the other
case where it was being given to apt, it actually just resulted in
duplication.

the chown command needed running within the chroot, since apt-get is being
run within the chroot and _apt might have a different UID there than on
the host.

when building within a home directory, as /proc, /sys, etc are mounted
and unmounted into the chroot at various points in the build, corresponding
entries appear and disappear within the side panel of nautilus.
this is obviously undesirable.
use of `-o x-gvfs-hide` resolves this for the most part. i still see items
occasionally pop up and having spent some time experimenting, i'm putting
it down to buggy behaviour on the part of nautilus. (aside from those
appearing when debootstrap is running - debootstrap also needs this fix).

Combine the check+create done in each script. (The original functions
are still callable as before, but a new combined `Aquire_lockfile`
function can be called instead, as now used).
Note, a further simplification could be done in removing the passing of
the lock filename in as a parameter since every use of the functions is
with ".lock". The lock functions already have a fallback to ".build/lock"
though. Checking the history, the fallback used to be for a system wide
lock, which was then replaced with this config-tree specific one. As long
as that is not used implicitly by 3rd-party hooks then surely we are free
to change the fallback to ".lock" and further remove passing in a name as
a param...?

previously this was white+bold. the white aspect was dropped since this
would not be sensible for users with a white background for their terminal.
bold however does not have any effect for me at least so effectively there
is no highlighting at all.
here we reintroduce a colour, one that will work for both black and white
backgrounds of course. purple looks good to me - significantly different
to that used for errors and warnings, and works well with command
highlighting (as enabled separately).
if a script exits due to a failure and `set -e`, we should ensure that an
error message is printed to be clear to the user that something actually
went wrong.
similarly it would be good to print a suitable message should the user
cancel with ctrl+c for instance.

theres no point in creation of stagefiles being kept within a
conditional block of work. if the script completes with success
then it should create its stagefile to thus avoid repeating any
work that it might have done should it get re-run without being
forced.
