[PATCH v2 0/2] Allow multiple keyspecs in one environment variable

[Jonas Rebmann <jre@pengutronix.de>]

This contains the actual change to keytoc as well a migration Note.

Allowing any number of public keys to be provided via a single
environment variable eases integration in more complex setups where
multiple public keys per keyring are managed externally.

Changes in v2:
- Split up the keyspec environment variables when multiple are provided
  too.
- Use strsep_unescape instead of manual split/unescape
- Remove RFC tag
- Link to v1: https://lore.barebox.org/barebox/20260206-keytoc-multi-env-v1-1-638fbf2b3634@pengutronix.de
