Add configure option to reduce visual clutter at boot time

If this option is enabled, then do all of the following:

Don't display introductory message about line editing unless we're
actually offering a shell prompt.  (This is believed to be a workaround
for a different bug.  We'll go with this for now, but will drop this in
favour of a better fix upstream if somebody figures out what that is.)

Don't clear the screen just before booting if we never drew the menu in
the first place.

Remove verbose messages printed before reading configuration.  In some
ways this is awkward because it makes debugging harder, but it's a
requirement for a smooth-looking boot process; we may be able to do
better in future.  Upstream doesn't want this, though.

Disable the cursor as well, for similar reasons of tidiness.

Suppress kernel/initrd progress messages, except in recovery mode.

Suppress "GRUB loading" message unless Shift is held down.  Upstream
doesn't want this, as it makes debugging harder.  Ubuntu wants it to
provide a cleaner boot experience.

Bail out if trying to run grub-mkconfig during upgrade to 2.00

Since files in /etc/grub.d/ are conffiles, they are not put in place
until grub-common is configured, meaning that they may be out of sync
with the parts of grub-mkconfig that reside in /usr/.  In GRUB 1.99,
/etc/grub.d/00_header contained a reference to ${GRUB_PREFIX}/video.lst.
This and other code from 1.99 breaks with 2.00's grub-mkconfig.
Deferring this to when grub-PLATFORM.postinst eventually runs is safe
and avoids this problem.

Restore grub-mkdevicemap

This is kind of a mess, requiring lots of OS-specific code to iterate
over all possible devices.  However, we use it in a number of scripts to
discover devices and reimplementing those in terms of something else
would be very complicated.

Handle filesystems loop-mounted on file images

Improve prepare_grub_to_access_device to emit appropriate commands for

This is needed for Ubuntu's Wubi installation method.

This patch isn't inherently Debian/Ubuntu-specific.  losetup and
/proc/mounts are Linux-specific, though, so we might need to refine this
before sending it upstream.  The changes to the Linux grub.d scripts
might be better handled by integrating 10_lupin properly instead.

Disable gfxpayload=keep by default

Setting gfxpayload=keep has been known to cause efifb to be
inappropriately enabled.  In any case, with the current Linux kernel the
result of this option is that early kernelspace will be unable to print
anything to the console, so (for example) if boot fails and you end up
dumped to an initramfs prompt, you won't be able to see anything on the
screen.  As such it shouldn't be enabled by default in Debian, no matter
what kernel options are enabled.

gfxpayload=keep is a good idea but rather ahead of its time ...
