armbian-next: the great cli entrypoint (+docker) rewrite; introduce USE_LOCAL_APT_DEB_CACHE replacing apt-cacher-ng
- armbian-next: introduce `USE_LOCAL_APT_DEB_CACHE` (default `=yes`) as alternative/in addition to `apt-cacher-ng` (eg, in Docker)
  - this uses `cache/aptcache/${RELEASE}-${ARCH}` (in the host) for
      - apt cache, by bind-mounting it to `${SDCARD}/var/cache/apt` in the `chroot_sdcard_apt_get()` runner and its usages
      - debootstrap, by passing it `--cache-dir`
  - utility function to help understand what is happening to cache during usage
  - apt itself mantains this cache, removing old packages when new ones are installed. apt does this _by default_
      - introduce `DONT_MAINTAIN_APT_CACHE=yes` to skip out of automatic apt maintenance of apt cache, eg, during `remove`s
      - don't do `apt clean` and such if using local cache, that would clean the cache, not the chroot
  - clean up `install_deb_chroot()` a little, find an unrelated bug there
- WiP: the great cli entrypoint (+docker) rewrite, Phase 6: relaunching structure; re-pass ARMBIAN_BUILD_UUID; use ARMBIAN_COMMAND for log filename; fix for output/logs dir perms
- WiP: the great cli entrypoint (+docker) rewrite, Phase 5: cleanups 4/x; better logging, check & force `DEST_LANG`
- WiP: the great cli entrypoint (+docker) rewrite, Phase 5: cleanups 3/x; don't write to stderr in generated Dockerfile
  - it's `drastic red` on non-buildx dockers
- WiP: the great cli entrypoint (+docker) rewrite, Phase 5: cleanups 2/x, logging
- WiP: the great cli entrypoint (+docker) rewrite, Phase 5: cleanups 1/x
  - source configs in a logging section.
  - Docker: silent, fast retries to make sure `docker system df` works
  - shut-up `chown` (no `-v`) output related to  `SET_OWNER_TO_UID`
  - ask user to wait while `DESTIMG` is rsync'ed to `FINALDEST` -- it's potentially very slow
  - use green apple for Mac logging, instead of red apple which might imply error...
- WiP: the great cli entrypoint (+docker) rewrite, Phase 4: run as non-root, maybe-with-Docker
  - introduce `is_docker_ready_to_go()`; if it is, and we're not root, use Docker instead of sudo. <- GOOD IDEA? BAD IDEA? lol
  - introduce `SET_OWNER_TO_UID` var to be passed to Docker/sudo so written files are owned by the launching user, not root.
    - introduce `mkdir_recursive_and_set_uid_owner()` and `reset_uid_owner()` to reset owner based on `SET_OWNER_TO_UID`
    - use it for userpatches files created, logs, and output files, including images and debs.
  - @TODOs ref. `$SUDO_USER` which I think the old version of this?
  - add a lot of @TODOs, ref being able to relaunch something that's not `build` inside Docker, also add/change params and configs and command.
    - initially add `ARMBIAN_DOCKER_RELAUNCH_EXTRA_ARGS`
- WiP: the great cli entrypoint (+docker) rewrite, Phase 3: rpardini is demented, v3
- WiP: the great cli entrypoint (+docker) rewrite, Phase 2: rpardini is demented
- WiP: the great cli entrypoint (+docker) rewrite, Phase 1
- armbian-next: WiP: Docker: actually use the GHA-image as base; pull it every 24hs.
  - using image in my private repo.
  - this has significant speedup to "start building time" on the 1st run
  - move some Linux specific stuff to its own if
  - add comments and todo
- armbian-next: WiP: Docker, high-WiP, beginnings of Armbian mount dict, with linux/darwin preferences
- armbian-next: WiP: Docker, configure `BUILDKIT_COLORS`
- armbian-next: WiP: Docker, make docker image from Dockerfile more compact by flattening layers
- armbian-next: `logging`: add whale indicator if build running under Docker
- armbian-next: WiP: `docker`: working with `bookworm`, `sid`, and `jammy` on Darwin & Linux; works with `bullseye` on Linux only
- armbian-next: WiP: `docker`: force ARMBIAN_RUNNING_IN_CONTAINER both in Dockerfile and passed as `--env`; apt update and install in same layer; back to jammy
- armbian-next: introduce `armbian_is_running_in_container()` and `armbian_is_host_running_systemd()`, replacing `systemd-detect-virt` in multiple spots
- WiP: try with debian:bullseye -- can't detect docker at all
- armbian-next: WiP: 2nd stab at new Docker support; Darwin still works; Linux `docker.io` working
  - gen .dockerignore together with Dockerfile
  - split in funcs
  - hacks for Linux and `/dev/loop` stuff, CONTAINER_COMPAT=yes
  - mac still works, Linux stuff would break it but I if'fed
- armbian-next: the secrets of `CONTAINER_COMPAT` revealed; add size checking to check_loop_device() and avoid retry when `mknod`ing
  - this fails for the right reasons now, causing retries, which are then retried and work ;-)
  - this is related to building under Docker on Linux, using docker.io package (not docker-ce)
- armbian-next: remove `.dockerignore` and add it to `.gitignore`; it's going to be auto-generated
- armbian-next: `.dockerignore`: Docker context should only have minimal files and folders, to speed up Dockerfile build
  - IMPORTANT: `.dockerignore` is going to be generated from now on: so this is the last commit with changes before removal
-  armbian-next: WiP: initial stab at new Docker support; really run the passed cmdline; add Dockerfile to gitignore
-  armbian-next: WiP: initial stab at new Docker support; generate Dockerfile; introduce REQUIREMENTS_DEFS_ONLY
  - uses REQUIREMENTS_DEFS_ONLY
  - works on Docker Desktop on Mac;
  - linux TBA
- armbian-next: don't error out if `.git` not present; other small fixes
- armbian-next: general "work or at least don't misbehave when run on a very bare ubuntu:latest instance"
  - can't assume things, for example:
  - that `sudo` will be available; it might not, and might be already root, no reason to fail
  - that `/etc/timezone` will exist
  - that `systemd-detect-virt` will be available
  - that `git` will be available
  - that `locale-gen` will be available
