* 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.

Now that pacman 6 is around, enable parallel downloads to speed up the installation

* nl6720/env-i-SOURCE_DATE_EPOCH:
  mkarchiso: pass SOURCE_DATE_EPOCH to chroot

* nl6720/update-wiki-url:
  Update ArchWiki article URLs

Use the new, prettier short URLs.

* sxw/issue25:
  Add documentation for the `script=` variable

* nl6720/pacman6:
  configs/*/pacman.conf: update configuration file for pacman 6

Based on https://github.com/archlinux/svntogit-packages/blob/accc1d210133a933f2b26e0aad842c27d00c8b0c/trunk/pacman.conf

Implements #136

* nl6720/ARCHISO_GNUPG_FD-unbound-variable:
  mkarchiso: fix unbound variable when not using GPG signing

Fixes #138

* nl6720/env-i:
  archiso/mkarchiso: clear environment variables when chrooting

Environment variables can interfere with the commands in chroot.
This causes issues when the environment variables specify a path that does not exist inside the chroot, e.g. if TMPDIR is set to a custom value.

Fixes https://bugs.archlinux.org/task/70580 .

  configs/releng/airootfs/etc/systemd/network/: match by globbing the interface name instead of matching the type

configs/releng/airootfs/etc/systemd/network/: match by globbing the interface name instead of matching the type

Type=ether matches virtual Ethernet interfaces (veth*) which may break networking inside containers.

kernel parameter is given

CHANGELOG.rst:
Add changelog entry for v54.

.gitlab-ci.yml:
Use environment variables to override the build settings offered by the build-host.sh script.
Lower the RAM usage of the builds to 3072.
Lower the COW space used by archiso to 2GiB.
Remove dependency on libisoburn in the `before_script` section of the build target (libarchive and util-linux have
replaced this requirement).
Use size units in accordance with upstream documentation.
Use the new name of the build's metrics file.

Fixes #134

.gitlab/ci/build-host.sh:
Change all script-local variables to lower-case and make some of them overridable using environment variables (by
providing defaults).
Break down overly long commands by splitting them into a list of strings.
Use local variables where possible.
Change `main()` to use rsync instead of cp to copy the project to the build location more generically.
Change `main()` to use rsync instead of cp to copy the build artifacts on the VM from the project's build directory to
the output.
Remove all unnecessary `function` keywords for function declarations.
Replace the dependency on libisoburn's `xorriso` with libarchive's `bsdtar` and util-linux's `blkid` in
`prepare_boot()`.
Add `print_section_start()` and `print_section_end()` to reduce code duplication and error potential when printing lines
for gitlab's collapsible sections (https://docs.gitlab.com/ee/ci/jobs/#custom-collapsible-sections).
Document the script's behavior and expectations.
Document the understood environment variables and add links to documentation on understood units (in case of size
units).
