TPM Disk Unlock Key sealing/renewal cleanup (Triggered automatically when resealing TOTP)
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
