gui-init: make sure that reseal_tpm_disk_decryption_key happens only on successful TOTP/HOTP sealing, reusing cached TPM Owner password

Add comments after reboot/poweroff to clarify what they do. These
commands are here partly for discoverability by users who might not
know what to do in a recovery shell, so clarifying their purpose helps
those users figure out what to do.

Some device firmware, such as the graphics microcontroller, is needed
during the initrd - i915 is often loaded in the initrd, and this is the
only chance to load GuC firmware.
Device firmware must still be available after the real root is mounted
too, so update the custom firmware path in the kernel when the firmware
is moved to /run.

Add Librem 11 board.
Librem 11 uses coreboot graphics init, which is done with FSP GOP.
Set a custom keymap for the volume/power keys. Configure the volume
keys as up/down arrows (for navigation in fbwhiptail, and for shell
history in the Linux console). Configure the power key as Enter.

Allow boards to optionally include loadkeys to set a custom keymap.
showkey and dumpkeys (normally only needed for development) can also be
optionally included.
Remove *.map from .gitignore; this was probably intended for build
artifacts that are now excluded via the build/ directory.
Add reboot and poweroff to shell history, which is useful for devices
lacking full hardware keyboards to escape the recovery shell with just
"up" and "enter".

Improve speed by pre-filtering only for lines containing any tokens of
interest to flashrom_progress_tokenize().
Improve reliability by avoiding dropping tokens that cross a stream
buffer boundary. Occasionally, a token could be missed if it crosses a
stream buffer boundary, due to read timing out too quickly before the
next buffer is flushed. If this was a state-changing token,
flashrom_progress() would hang forever.

* use GPG_ALGO as gpg key generation algorithm
* determine GPG_ALGO during runtime like this:
* if CONFIG_GPG_ALGO is set, use as preference
* adapt based on usb-token capabilities (currently only Nitrokey 3)
Changes:
- As per master: when TOTP cannot unseal TOTP, user is prompted to either reset or regenerate TOTP
- Now, when either is done and a previous TPM Disk Unlock Key was setuped, the user is guided into:
- Regenerating checksums and signing them
- Regenerating TPM disk Unlock Key and resealing TPM disk Unlock Key with passphrase into TPM
- LUKS header being modified, user is asked to resign kexec.sig one last time prior of being able to default boot
- When no previous Disk Unlock Key was setuped, the user is guided into:
- The above, plus
- Detection of LUKS containers,suggesting only relevant partitions
- Addition of TRACE and DEBUG statements to troubleshoot actual vs expected behavior while coding
- Were missing under TPM Disk Unlock Key setup codepaths
- Fixes for #645 : We now check if only one slots exists and we do not use it if its slot1.
- Also shows in DEBUG traces now
Unrelated staged changes
- ash_functions: warn and die now contains proper spacing and eye attaction
- all warn and die calls modified if containing warnings and too much punctuation
- unify usage of term TPM Disk Unlock Key and Disk Recovery Key
prepare_thumb_drive: default to creating 10% LUKS container on usb drive, prompts for passphrase is not provided and scan drives if no --device specified
NOTE: qemu usb_thumb drive of 128 mb are not big enough so that 10% of it (12mb) can be used to create thumb drive.
Adds:
- e2fsprogs to support ext4 filesystem creation through mke2fs
- add /etc/mke2fs.conf so that mke2fs knows how to handle ext2/ext3/ext4
- removes mke2fs support from busybox
- bump busybox to latest version which adds cpu accelerated hash functions (not needed per se here)
- Adds exfatprogs to have mkfs.exfat and fsck.exfat
- Adds prepare_thumb_drive /etc/luks-functions to be able to prepare a thumb drive with percentage of drive assigned to LUKS, rest to exfat
- Modify most board configs to test space requirements failing
- Talos2 linux config: add staging Exfat support
- Make e2fsprogs and exfatprogs included by default unless explicitely deactivate in board configs
- Change cryptsetup calls : luksOpen to open and luksClose to close to addresss review
- etc/luks_functions: cleanup
GOAL here is to have secure thumb drive creation which Heads will be able to use to backup/restore/use generated GPG key material in the future (next PR)
Based on feedback, 1440p displays can benefit from 2x console as well.
Err toward a font too large rather than too small and lower the
threshold to 1350, which is the threshold fbwhiptail uses for 1.5x.

Build kbd and ship setfont if enabled with CONFIG_KBD.
When CONFIG_KBD is enabled, setconsolefont.sh will double the console
font size on large displays (>1600 lines tall as a heuristic).

On platforms using CONFIG_BOOT_EXTRA_TTYS multiple processes may try to
access TPM at the same time, failing with EBUSY. The order of execution
is unpredictable, so the error may appear on main console, secondary one,
or neither of them if the calls are sufficiently staggered. Try up to
three times (including previous one) with small delays in case of error,
instead of immediately scaring users with "you've been pwned" message.

Updated cbmem searches for CBMEM exposed by kernel in sysfs before
trying to read it from memory directly. As such, there is no need for
pointing to that file explicitly.
New coreboot revision also fixes output of 'cbmem -t' caused by wrong
endianness.

Simplify "enable" prompt a bit, clarify that firmware updating is
blocked, and remove mention of "failsafe boot mode". Reword "disable"
prompt similarly.

The early recovery shell ("hold R") and serial recovery both could
bypass Restricted Boot since they occurred before config.user was
loaded. Load config.user earlier before these recovery methods.
Executing a shell directly (if recovery failed) also would bypass
Restricted Boot, additionally leaking /tmp/secret. Remove this from
the early recovery shell logic. Also remove the final failsafe exec
and move the "just in case" recovery from normal boot here instead, in
case the regular init script fails.

The -s mode was removed, remove it from usage. Remove the test to skip
checking for board flashrom options with -s mode.

The "disable restricted boot" prompt got slightly too long when fixing
the TPM wording. Re-wrap that line to match the others. Wrapping
could use some general cleanup but this is sufficient so the text isn't
truncated.

The CONFIG_BASIC test was backwards, as a result it skipped the
LUKS disk unlock logic if basic mode was _not_ enabled. This wasn't
observed in the PureBoot distribution because we disable the LUKS disk
unlock feature.
CONFIG_BOOT_REQ_ROLLBACK and CONFIG_BOOT_REQ_HASH logic was also
skipped incorrectly, though neither of these are enabled on any board
so this had no effect in the PureBoot distribution either.
Test basic with each bit of logic to eliminate duplication of the
kexec-boot call and fix the LUKS disk unlock feature.

Only try the default PIN automatically for 1 month after key creation.
This simplifies initial ownership but still encourages changing the
PIN.
Never enter a PIN automatically if fewer than 3 attempts remain, to
avoid causing lockout if the PIN has been changed.
Remind what the default PIN was if it is not attempted for either
reason.

HOTP/TOTP secrets don't have to be printable. Use binary data to
include 160 bits of entropy instead of just 80.
The secret is still limited to 20 bytes. Most keys now support up to
40 bytes, but tpmtotp is still limited to 20 bytes.
Move the truncation to 20 bytes a bit later, for future improvements to
detect the key's actual limit.

flash.sh had a special mode to read (like -r) and then sha256sum the
resulting file. This is no different from just a read followed by a
sha256sum, and the only caller also had logic to sha256sum a cached
file anyway.
Just use flash.sh -r and sha256sum the result.
