archiso/mkarchiso:
Do not run `_build_iso_base` with `_run_once`, as it sets variables which are important to functions that are called
after it.

* nl6720/bootmodes-2:
  mkarchiso: improve functions and comments

* Merge _make_efi_dir_on_iso9660 into _make_bootmode_uefi-x64.systemd-boot.eltorito since it's specific to that boot mode.
* Split off FAT image creation into _make_efibootimg, so it can be reused by other functions.
* Add/improve comments to better document what the script does.

* nl6720/RouteMetric:
  configs/*/airootfs/etc/systemd/system/systemd-networkd-wait-online.service.d/wait-for-only-one-interface.conf: document why the drop-in file exists
  configs/releng/airootfs/etc/systemd/network/: move RouteMetric= from [DHCPv6] to [IPv6AcceptRA]

configs/*/airootfs/etc/systemd/system/systemd-networkd-wait-online.service.d/wait-for-only-one-interface.conf: document why the drop-in file exists

Related to #142.

Add missing `ExecStart=` to baseline's /etc/systemd/system/systemd-networkd-wait-online.service.d/wait-for-only-one-interface.conf.

systemd moved the option. See https://github.com/systemd/systemd/commit/8ebafba9f987c21aa5787c8767f2e390b4ec0bc5 .
Implements #123.

Document in comments why the route metrics need to be set (because of https://github.com/systemd/systemd/issues/17698 ) and use the same metric values as NetworkManager. https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/main/src/core/devices/nm-device.c

Additionally remove RouteMetric from configs/baseline/airootfs/etc/systemd/network/20-ethernet.network.
There is only one networkd configuration file in baseline, meaning, there are no other routes.

  mkarchiso: set LC_ALL instead of LANG

LC_ALL overrides LANG and all LC_* variables, so use it instead.

* issues/140:
  Remove build-host.sh
  gitlab-ci: Include from ci-scripts
  ci: Provide artifacts in top-level output dir
  Rename build script

.gitlab/ci/build-host.sh:
Remove script, as it has been replaced by ci-scripts.

.gitlab-ci.yml:
Include a gitlab CI yaml file from the ci-scripts repository, that replaces the build-host.sh script and abstracts the
.build target.
Move all variables to top-level as they are useful in all build targets.
Remove unnecessary before_script definitions because they are abstracted away by ci-scripts.

.gitlab/ci/build-inside-vm.sh:
Change the build script to provide the build artifacts and metrics in the top-level output directory.
This goes in line with the soon to be used ci-scripts, allowing code sharing amongst several projects.

.gitlab/ci/build_archiso.sh:
Rename .gitlab/ci/build-inside-vm.sh to .gitlab/ci/build_archiso.sh.

.gitlab-ci.yml:
Rename BUILD_SCRIPT to build_archiso.sh.

* issues/132:
  gitlab-ci: Also build a baseline netboot target
  archiso/mkarchiso: Generalize handling of ucodes

.gitlab-ci.yml:
With #132 being fixed, it is possible to properly build the baseline netboot target without failure.

archiso/mkarchiso:
Generalize the handling of ucode files (e.g. copying, signing, size calculation) by introducing the global readonly
array of expected ucode names instead of hardcoding them in various functions.
When making use of ucode files in `_make_boot_on_iso9660()`, `_make_bootmode_uef-x86.systemd-boot.esp()` and
`_sign_netboot_artifacts()` create a list of files that is guaranteed to contain existing files.

Fixes #132

* grazzolini/parallel_downloads:
  baseline/pacman.conf: Enable parallel downloads
  releng/pacman.conf: Enable parallel downloads

Now that pacman 6 is around, enable parallel downloads to speed up the installation
process. Added to the baseline configuration to also improve the pipeline.
