`base-apt` is a local apt repository containing all upstream (Debian, Raspberry Pi OS, Ubuntu...) packages needed for a particular build. This series implements upfront repository downloading. This is the first step towards local partial mirror management.

The current approach in `next`:

- On the first build, debootstrap and sbuild are used for building Isar artifacts. The packages downloaded from the Internet are cached in local directories.
- On the next build:
- Analyze the logs from the previous build, save packages downloaded by the bootstraps, sbuilds and imagers into `base-apt`.
- Use `base-apt` for bootstrapping, building and image creation.

Some issues with the current approach:

1. Different policies must be followed for the first and the subsequent builds.
2. As we have multiple versions of the same package from the main and security repositories and rely on build logs and `find` for populating `base-apt`, extra care must be taken to ensure that the right package version lands in `base-apt`.
3. We rely on internal implementation of `debootstrap` and `sbuild` for saving and reusing the packages. Changing to e.g. `mmdebstrap` breaks the unrelated `base-apt` functionality.
4. Source packages are stored in a different flat directory, `apt-get source` for upstream packages is not possible.
5. At the moment of `base-apt` creation all we have is the package name. The knowledge about the upstream repositories is lost and no local repository policy implementation is possible (e.g., for the "multiple products, multiple distros" use case).
6. For implementing further use cases like "fetch all sources necessary for bootstrapping the base system itself", additional logic is necessary.

The new approach:

- On the first build:
- All packages necessary for bootstrapping and building are identified and downloaded upfront.
- `base-apt` is used for bootstrapping, building and image creation.
- On the next build:
- `base-apt` is used for bootstrapping, building and image creation.

This series addresses issues 1-5 and provides the architecture for implementing further use cases.

The new approach is enabled by default. Setting `ISAR_PREFETCH_BASE_APT` to zero falls back to the old approach.

The implementation uses `debrepo` script which can also be called manually for pre-fetching packages to the local 'base-apt' repository. It requires `python3-apt` to be installed on the build host. Some examples of its usage in standalone mode:

```
# Create local `/build/ba` repository sufficient to debootstrap Debian system with `armhf` architecture:
debrepo --init --workdir=/build/dr --repodir=/build/ba --arch=armhf

# Add some packages to this repo (e.g., build deps for some recipe):
debrepo --workdir=/build/dr locales gnupg

# Add srcpackages for some package to the repo:
debrepo --workdir=/build/dr --srcmode tzdata
```

Changes since v6:
- Rebased on latest next.
- Fixed possible stuck when `cache-deb-src` feature was enabled.
- Fixed support of debian build profiles.
- Moved locking of `debrepo` context from the bbclass to the script itself. This makes usage from Isar simpler.

Changes since v5:
- Rebased on latest next.
- Changed order of the patches.
- Fixes in `debrepo` script that allow to use it outside Isar in standalone mode.

Changes since v4:
- Rebased on latest next.
- Rearranged patches since some of them are already in next.
- Added possibility to select between new "prefetch" base-apt mode and old behaviour when it's populated on 2nd build with packages downloaded during 1st build. New behaviour is disabled by default, but enabled in local.conf.example for testing purposes.
- Code passes both full and fast CI in both "old" and "new" modes.

Changes since v3:
- Rebased on latest next.
- Cross-building for raspberry supported.
- Code passes both full and fast CI.

Changes since v2:
- Populate base-apt before using at all steps of native build.

Changes since v1:
- Rebased on latest next.
- Updated patchset description.

This means only local URLs in apt sources.list* are present during
the build. Any installation of packages is done from local base-apt.
So, base-apt should be always mounted in *_do_mounts since now.

This patch makes local base-apt repo to be created before
debootstrap task. So, debootstrap is then done from it.

The required packages are downloaded via python-apt and
reprepro creates debian-like repository from .deb files.

For debian targets host keyring is used while ubuntu/raspbian
targets use keys specified by DISTRO_BOOTSTRAP_KEYS variable.

The goal is have workable base-apt repo before first build completed.

This makes Isar use `base-apt` repo in different way. Any package
installation is done from `base-apt` repo which is prepopulated
from external mirrors.

This behaviour is disabled by default for downstreams. To enable it,
set the variable to "1", like isar does in local.conf.sample.

In order to be able to run CI in old mode, allow CI read the option
from the environment. Also, adjust some tests (like repro one) to
make them work with ISAR_PREFETCH_BASE_APT set.

This is the main utility responsible for prefetching packages
into local `base-apt` repo from external Debian mirrors. It uses
python-apt module and requires some kind of minimal `rootfs` to work
(let's call it "debrepo context").

Once initialized with `--init --workdir=<path>`, it stores the initial
configuration in `repo.opts` file inside the context and uses it at
futher calls.

In future, the logic `debrepo` script implements could be directly
implemented inside bitbake classes.

+# debrepo: build Debian-like repo using "python3-apt" library.
+
+When building the image, Isar downloads required Debian packages from external
+mirrors. After build completed, it can pick all downloaded packages from DL_DIR
+and build local 'base-apt' Debian-like repo from them.
+
+This tool allows to download packages and create local repo in advance. So,
+Isar just uses this local repository and does not interact with external
+mirrors. Such approach makes deb-dl import/export functionality redundant.
+
+Script `debrepo` works in so-called "context" directory. It means some
+rootfs-like directory with bare minimum of directories/files required for
+python3-apt to work.
+
+Context directory path is passed with "--workdir <dir>" command-line option.
+On context creating, all passed parameters are stored in the context directory
+and picked every time the context is used again.
+
+1. Repo for building Debian system
+```
+debrepo --workdir=d12 --init locales gnupg
+```
+Initialize the context in "d12" directory and create a repository in
+"d12/repo/apt" directory sufficient to debootstrap default system
+(e.g., debian-bookworm-amd64). Additionally, packages "locales" and "gnupg"
+with all their dependencies will be available in this repo.
+
+```
+debrepo --workdir=d12 docbook-to-man
+```
+Adds "docbook-to-man" packages with its dependencies to earlier created repo.
+
+```
+debrepo --workdir=d12 --srcmode docbook-to-man
+```
+Downloads source package for "docbook-to-man" and adds it to the repo
+
+2. Repo for building Ubuntu system
+```
+debrepo --init --workdir=uf \
+--distro=ubuntu --codename=focal --arch=arm64 \
+--aptsrcsfile=/work/isar/meta-isar/conf/distro/ubuntu-focal-ports.list \
+--repodir=repo/apt --repodbdir=repo/db \
+--mirror=http://ports.ubuntu.com/ubuntu-ports \
+locales gnupg
+```
+Initialize the context in "uf" directory and create a repository in "repo/apt"
+directory sufficient deboostraup ubuntu-focal arm64 system. Mirror to use and
+source list are specified by corresponding arguments. Packages "locales" and
+" gnupg" with the dependencies will be also placed to the repo.
+
+```
+debrepo --workdir=uf gnupg,locales
+```
+Add "gnupg" and "locales" packages with their dependencies to earlier created
+ubuntu repo. Other parameters (distro, codename, arch) are ommited since they
+are picked from the context.
+
+3. Repo for cross-building Debian system
+```
+debrepo --init --workdir=d11 --codename=bullseye--arch=amd64 --crossarch=armhf
+```
+Initialize the context in "d11" directory sufficient to deboostrap Debian
+Bullseye (amd64) with foreign "armhf" architecture support
+
+```
+debrepo --workdir=d11 gcc
+```
+Add "gcc" package (amd64 version) to earlier created repo.
+
+```
+debrepo --workdir=d11 --crossbuild gcc
+```
+Add "gcc" package (armhf version) to earlier created repo.

This is mostly related to gitlab CI that migth use an image without
preinstalled python3-apt.

Also, make system python packages available in virtualenv.

Since all packages and source packages are placed to base-apt repo
during build, there is no need to have them in one more place.

This option allows to set ISAR_PREFETCH_BASE_APT to "0" or "1" and
choose between old and new base-apt behaviour.

Docker image kas uses should have "python3-apt" preinstalled
in order to have new functionality working.
