Minimise writes to EFI variable storage

Some UEFI firmware is easily provoked into running out of space in its
variable storage.  This is usually due to certain kernel drivers (e.g.
pstore), but regardless of the cause it can cause grub-install to fail
because it currently asks efibootmgr to delete and re-add entries, and
the deletion often doesn't result in an immediate garbage collection.
Writing variables frequently also increases wear on the NVRAM which may
have limited write cycles.  For these reasons, it's desirable to find a
way to minimise writes while still allowing grub-install to ensure that
a suitable boot entry exists.

Unfortunately, efibootmgr doesn't offer an interface that would let
grub-install do this.  It doesn't in general make very much effort to
minimise writes; it doesn't allow modifying an existing Boot* variable
entry, except in certain limited ways; and current versions don't have a
way to export the expected variable data so that grub-install can
compare it to the current data.  While it would be possible (and perhaps
desirable?) to add at least some of this to efibootmgr, that would still
leave the problem that there isn't a good upstreamable way for
grub-install to guarantee that it has a new enough version of
efibootmgr.  In any case, it's cumbersome and slow for grub-install to
have to fork efibootmgr to get things done.

Fortunately, a few years ago Peter Jones helpfully factored out a
substantial part of efibootmgr to the efivar and efiboot libraries, and
so it's now possible to have grub-install use those directly.  We still
have to use some code from efibootmgr, but much less than would
previously have been necessary.

grub-install now reuses existing boot entries where possible, and avoids
writing to variables when the new contents are the same as the old
contents.  In the common upgrade case where nothing needs to change, it
no longer writes to NVRAM at all.  It's also now slightly faster, since
using libefivar is faster than forking efibootmgr.

Fix setup on Secure Boot systems where cryptodisk is in use

On full-encrypted systems, including /boot, the current code omits
cryptodisk commands needed to open the drives if Secure Boot is enabled.
This prevents grub2 from reading any further configuration residing on
the encrypted disk.
This patch fixes this issue by adding the needed "cryptomount" commands in

normal/main: Discover the device to read the config from as a fallback

When core.img is generated locally, the grub2-probe tool figures out the
device and partition that needs to be read to parse the GRUB
configuration file.

But in some cases the core.img can't be generated on the host and
instead has to be done at package build time.  In particular, this will
be true when it needs to be signed with a key that's only available on
the package building infrastructure.

In that case, the prefix variable won't have a device and partition but
only a directory path.  So there's no way for GRUB to know from which
device has to read the configuration file.

To allow GRUB to continue working on that scenario, fallback to
iterating over all the available devices if reading the config failed
when using the prefix and fw_path variables.

http: Prepend prefix when the HTTP path is relative

There are two different HTTP drivers that can be used when requesting an
HTTP resource: the efi/http that uses the EFI_HTTP_PROTOCOL and the http
that uses GRUB's HTTP and TCP/IP implementation.

The efi/http driver appends a prefix that is defined in the variable
http_path, but the http driver doesn't.  So using this driver and
attempting to fetch a resource using a relative path fails.  Match the
behavior of efi/http.

efi/http: Enclose literal IPv6 addresses in square brackets

According to RFC 2732 (https://www.ietf.org/rfc/rfc2732.txt), literal IPv6
addresses must be enclosed in square brackets. But GRUB currently does not
do this and is causing HTTP servers to send Bad Request (400) responses.

For example, the following is the HTTP stream when fetching a config file:

HEAD /EFI/BOOT/grub.cfg HTTP/1.1
Host: 2000:dead:beef:a::1
Accept: */*
User-Agent: UefiHttpBoot/1.0

Server: Apache/2.4.41 (Fedora) OpenSSL/1.1.1d
Connection: close
Content-Type: text/html; charset=iso-8859-1

and after enclosing the IPv6 address the HTTP request is successful:

HEAD /EFI/BOOT/grub.cfg HTTP/1.1
Host: [2000:dead:beef:a::1]
Accept: */*

If we don't have writable grubenv and we're on EFI, always show the menu

If we don't have writable grubenv, recordfail doesn't work, which means our
quickboot behavior - with a timeout of 0 - leaves the user without a
reliable way to access the boot menu if they're on UEFI, because unlike
BIOS, UEFI does not support checking the state of modifier keys (i.e.
holding down shift at boot is not detectable).

Handle this corner case by always using a non-zero timeout on EFI when
save_env doesn't work.

Reuse GRUB_RECORDFAIL_TIMEOUT to avoid introducing another variable.

Add configure option to bypass boot menu if possible

If other operating systems are installed, then automatically unhide the
menu.  Otherwise, if GRUB_HIDDEN_TIMEOUT is 0, then use keystatus if
available to check whether Shift is pressed.  If it is, show the menu,
otherwise boot immediately.  If keystatus is not available, then fall
back to a short delay interruptible with Escape.

This may or may not remain Ubuntu-specific, although it's not obviously
wanted upstream.  It implements a requirement of
https://wiki.ubuntu.com/DesktopExperienceTeam/KarmicBootExperienceDesignSpec#Bootloader.

If the previous boot failed (defined as failing to get to the end of one
of the normal runlevels), then show the boot menu regardless.

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.

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 ...
