All boards with CONFIG_LINUX_USB=y ship ehci-* and xhci-*, they are
not controlled by CONFIG_LINUX_USB_COMPANION_CONTROLLER. Always
insert them when initializing USB. Fixes commit 35de2348

When testing a possible boot device, detect its partition type and
skip grub, LUKS, and LVM partitions. These aren't mountable as /boot,
this silences spurious exFAT errors.
In detect_boot_device, skip testing CONFIG_BOOT_DEV a second time if it
is found as a block device. This avoids doubling any errors shown from
checking this device, no sense trying it twice.
Refactor some logic to avoid duplication - extract
device_has_partitions and use it in detect_boot_device, extract
mount_possible_boot_device and use it instead of duplicating the logic.
Move find_lvm_vg_name() to /etc/functions.
Avoid mixing up similarly-named devices like 'nvme0n1'/'nvme0n10' or
'sda'/'sdaa' - it's probably unlikely that many devices will appear,
but looking for partitions in '/sys/class/block/<device>/' instead of
'/dev/' would avoid any collisions.

Exception: scripts sourcing/calls within etc/ash_functions continues to use old TRACE functions until we switch to bash completely getting rid of ash.
This would mean getting rid of legacy boards (flash + legacy boards which do not have enough space for bash in flash boards) once and for all.

When playing with long fbwhiptail/whiptail messages, this commit played around the long string using fold.
'''
echo -e "This will replace the encrypted container content and its LUKS Disk Recovery Key.\n\nThe passphrase associated with this key will be asked from the user under the following conditions:\n 1-Every boot if no Disk Unlock Key was added to the TPM\n 2-If the TPM fails (hardware failure)\n 3-If the firmware has been tampered with/modified by the user\n\nThis process requires you to type the current LUKS Disk Recovery Key passphrase and will delete the LUKS TPM Disk Unlock Key slot, if set up, by setting a default boot LUKS key slot (1) if present.\n\nAt the next prompt, you may be asked to select which file corresponds to the LUKS device container.\n\nHit Enter to continue." | fold -w 70 -s
'''
Which gave the exact output of what will be inside of the fbwhiptail prompt, fixed to 70 chars width:
'''
This will replace the encrypted container content and its LUKS Disk
Recovery Key.
The passphrase associated with this key will be asked from the user
under the following conditions:
1-Every boot if no Disk Unlock Key was added to the TPM
2-If the TPM fails (hardware failure)
3-If the firmware has been tampered with/modified by the user
This process requires you to type the current LUKS Disk Recovery Key
passphrase and will delete the LUKS TPM Disk Unlock Key slot, if set
up, by setting a default boot LUKS key slot (1) if present.
At the next prompt, you may be asked to select which file corresponds
to the LUKS device container.
Hit Enter to continue.
'''
Therefore, for long prompts in the future, one can just deal with "\n 1-" alignments to be respected in prompts and have fold deal with cutting the length of strings properly.

Add TRACE_FUNC to trace the file, line, and name of the calling
function. File and function names don't have to be duplicated in a
TRACE statement with this (they tend to become inaccurate as functions
are renamed and the TRACE statement is forgotten).
Add DEBUG_STACK to dump the bash stack to debug output.
Configure bash with --enable-debugger. Bash doesn't actually include
the entire debugger, this is just some supporting variables for it.
Evidently, BASH_SOURCE[n] is only set within a function if this is
enabled. I couldn't find this indicated in any documentation, but it
happened in practice.
Compressed initrd size only increased by 2560 bytes for librem_mini_v2,
I think that is fine. This also gives us BASH_ARGC/BASH_ARGV which
might be useful for diagnostics.

Laptops can include optional USB keyboard support (default off unless
the board also sets the default to 'y'). The setting is in the
configuration GUI.
CONFIG_USER_USB_KEYBOARD is now the user-controlled setting on those
boards. 'CONFIG_USB_KEYBOARD' is no longer used to avoid any conflict
with prior releases that expect this to be a compile-time setting only
(conflicts risk total lock out requiring hardware flash, so some
caution is justified IMO).
Boards previously exporting CONFIG_USB_KEYBOARD now export
CONFIG_USB_KEYBOARD_REQUIRED. Those boards don't have built-in
keyboards, USB keyboard is always enabled. (librem_mini,
librem_mini_v2, librem_11, librem_l1um, librem_l1um_v2, talos-2,
kgpe-d16_workstation-usb_keyboard, x230-hotp-maximized_usb-kb).
Librem laptops now export CONFIG_SUPPORT_USB_KEYBOARD to enable
optional support. The default is still 'off'.

Removed all mentions of a "Recovery Disk Key" and replaced with "Disk Recovery Key".
Fixed some grammatical errors.
Added check for new passphrase in reencrypt function to accommodate switching of reencrypt and new passphrase setting order in oem-factory-reset.

Move confirmation of formatting flash drive with LUKS percentage
selection before any reset actions have been taken, so aborting does
not result in a half-reset system. Combine with the more basic
"confirm" prompt that existed after selecting the device (but did not
include the LUKS size information).
Split up prepare_flash_drive into interactive_prepare_flash_drive (both
prompts and formats as before), confirm_thumb_drive_format (just
confirms the selections), and prepare_thumb_drive (now noninteractive).

Combine prompt to disconnect other devices with prompt to connect the
desired device.
Show block device sizes in MB/GB when selecting device so it is easier
to select. file_selector now supports --show-size to include block
device sizes in menu.
Rework file_selector so menu options can contain spaces (use bash
array) and to simplify logic.
Prompt to select flash drive and LUKS percentage in OEM reset before
actually taking any actions, so aborting doesn't half-reset the system.
Abort OEM reset if user aborts the flash drive selection instead of
looping forever. (Canceling the confirmation still loops to retry but
it is possible to exit by aborting the repeated menu.)

gui-init: make sure that reseal_tpm_disk_decryption_key happens only on successful TOTP/HOTP sealing, reusing cached TPM Owner password
Signed-off-by: Thierry Laurion <insurgo@riseup.net>
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
