tpm2-tools-5.6 patch: comment out git versioning output under ./VERSION; module: output current version under ./VERSION instead. Document under module

hardcode VERSION='reproducible_build' into generated configure script to get rid of generate random git abbrev 8/12 chars (could not find source)
patches/openssl-3.0.8.patch: clean up
tpm2-tools/tpm2-tss:
hack configure scripts to not contain hardcoded libs and other rpath related strings, using sed instead of patching configure script like cryptsetup2 patch
Will be clened up in other commits. Leaving here as trace for autotools sed patching for reproducible builds.
CircleCI: change working dir from project->heads so that CircleCI and local builds are from heads directory, helping reproducible builds
TODO: change other patches a well and generalize to gpg toolstack, removing patches that are a maintainership burden.

- Add additional requirements to linux config
- Add additional CONFIG_MOBILE_TETHERING=y to all maximized board configs
- Fix issue under network-recovery-init to NTP sync against NTP server pool
- Extend network-recovery-init to first try NTP sync against DNS server returned by DHCP answer
- Remove network-recovery-init earlytty and tty0 redirection (console should be setuped properly by init in all cases)
- If CONFIG_MOBILE_TETHERING=y added to board config and network-recovery-init called, wait to user input on instructions and warning 30 secs before proceeding (non-blocking)
- Machines having STATIC_IP under board config won't benefit of autoatic NTP sync
Since network-recovery-init can only be called from recovery shell now, and recovery shell can be guarded by GPG auth, this is PoC code to be used to complement TOTP being out of sync
TODO(Future PR):
- Refactor into functions and reuse into TOTP/HOTP being out of sync automatically.

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.

Since exFAT support was enabled, mounting an iso9660 filesystem prints
spurious exFAT errors to the console. That is because busybox mount
tries all filesystems in the order listed, and exfat precedes iso9660
(those are the last two in our config). Most filesystems are silent
when used on the wrong type of filesystem, but exFAT logs errors, which
appear on the console.
Move exFAT after iso9660, so iso9660 filesystems won't show these
errors. The errors will still appear if the filesystem is actually
exFAT but cannot be mounted.
There's no significant risk of misdetecting a remnant iso9660
superblock here either. Although an iso9660 superblock could fall in
the unused space between the exFAT boot region and the FAT itself,
mkfs.exfat does zero this space so it is unlikely such a remnant
superblock would exist.

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.

Next steps on this is introspection and PCRs reconstruction helpers, which will output in DEBUG and be usable from recovery shell.
We have to keep in mind that providing those tools is useful in DEBUG mode and for users having access to Recovery Shell.
But currently, having access to cbmem -L output and final PCRs content is making it too easy for Evil Maid to know what needs to be hardcoded to pass measured boot.

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.

Don't spew the root hashes to the console when creating the hash file.
This speeds up hash creation significantly. A basic Qubes install on a
cheap (slow) SATA SSD reduced from about 1.5 minutes to just under 1
minute, and a PureOS install on a fast NVMe disk reduced from 2.5
minutes to 1 minute.
Support opening LVM volume groups to find the root disk. If an LVM PV
is found, its group is opened and the 'root' volume is used. There is
no way to set the volume name in this iteration; this is the default
name used by Qubes and probably common to many LVM OS installations.
LUKS and LVM can be mixed. Tested LUKS (PureOS) and LUKS+LVM (Qubes).
Always cd to "$ROOT_MOUNT" in a subshell, improves robustness of
scripts (previously some functions only worked if they were called
after another function had cd'd to "$ROOT_MOUNT").

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.
