Add function to detect boot device. Start by checking
CONFIG_BOOT_DEV, then iterate thru all bootable partitions.
Check if partition is mountable, contains grub directory.
Update CONFIG_BOOT_DEV and mount on /boot if successful.

Initial card detection can sometimes fail, so prompt the user
to remove/reinsert their GPG card before retrying. Since
errexit is likely set, disable it prior to calling --card-status so
we can handle the error ourself, then re-set if necessary when done.

Updating TOTP/HOTP is mainly necessary after a user updates

use similar filtering logic as with USB drives to provide
the user a more sane list of boot device options. Show user
only valid bootable partitions, not block devices.
There's no point in showing /dev/nvme0 and /dev/nvme0n1 (eg)
when /dev/nvme0n1p[1..n] (eg) exist, as the former are not
valid boot devices.

Add optional parameter to bypass menu selection and

Introduce option to remove any existing key(s) from firmware
and add a user-suppled key, before reflashing.
Move existing code for adding a new key to a separate function

If CONFIG_BOOT_DEV isn't set or otherwise fails to mount,
we prompt the user to change the /boot device, but never
attempt to mount it to ensure it's sane, leading to
potential failures later in the config/boot process.
Ensure that CONFIG_BOOT_DEV is updated after the /boot device
is changed, and attempt to re-mount /boot after the change.

If the user has changed the /boot config but not yet flashed,
it's reasonable for them to expect that flashing to add/update
a GPG key won't revert those changes.

In order to streamline the initial setup, prompt user to

Move the non-GUI component of update_checksums() to
/etc/functions so it can be reused outside of gui-init.
Add check that /boot/kexec_default_hashes.txt exists before parsing
it, since doesn't exist if there's no default boot target set yet.

Before anything else, ensure that a default boot device

If /boot isn't mounted, we can't read the HOTP secret, so no
point in reading from the TPM. This speeds up getting to the
main menu in the case of an inaccessible or non-existant /boot,
and maintains the warning condition from not being able to
validate the HOTP.

Exclude dot folders from ROM search path, so that files in

Using sort on USB boot options produces a reverse-ordered list,
leading users to often select the wrong option. Add the -r
parameter to sort to correct the list order and make the default
option the first in the list.

Because of the way unseal-hotp is called from gui-init,
dropping to a recovery shell when failing to mount /boot
causes it to hang, leaving the user stranded until they
kill it with CTRL+C. Instead, simply return and continue
to the main GUI menu where the user can address the problem.
Rename the function to clarify difference from other versions
of mount_boot() which do drop to the recovery shell.

Reading the file into a variable and then redirecting to stdin
via echo() can cause the binary data to be truncated, leading
to an invalid base32 value and failure to properly generate
and validate the HOTP code.
To resolve this, pass the file directly to hotp(), and ensure
it is removed properly regardless of success or failure to
prevent leakage.
Fixes "Invalid base32 string" error seen when attempting to
generate a new TOTP secret.

Add a main boot menu entry to power off. This enables users to
only verify the firmware integrity using OTP, and do nothing more.
After having left the device out of sight, one might want to do
a quick sanity check only.
Since we already have a script to safely power down, we make use of
it now.
