- artifacts: u-boot/kernel - pt7 - adapt legacy/artifact versions; use common `capture_rename_legacy_debs_into_artifacts()`
- artifacts: u-boot - pt6: add artifact for u-boot
- use artifact version / reason in actual u-boot .deb if present
- artifacts: kernel - pt5: tune kernel version, refactor
- artifacts: kernel - pt4: squash unrelated bugs that show up; move `prepare_compilation_vars()` to default build
- artifacts: kernel - pt3: drivers+patches+.config hashing
- split file hashing function from drivers-harness; fix it so filenames are relative and sorted; sort from ${SRC}, always
- aplit prepare_kernel_config_core_or_userpatches() from `kernel_config_initialize()`
- artifacts: kernel - pt2: memoizing git ref2info
- artifacts: kernel - pt1: versioning
