Place custom mkinitcpio.conf in airootfs.
Use a custom mkinitcpio preset to specify generated image file path.

LICENSE:
Add GPL-3.0 license.

{{archiso,configs}/*,.editorconfig,.gitlab-ci.yml}:
Add SPDX license identifier.

Makefile:
Add SPDX license identifier.
Install the `run_archiso.sh` script as global executable `run_archiso`.
Use -D and -t flags to install to install files more generically (without a previous call to install the directory).

README.rst:
Add README outlining the project's scope, how to build images from the profiles and how to test.

AUTHORS.rst:
Add list of all direct contributors to the repository.

CONTRIBUTING.rst:
Add basic contribution guidelines, explaining the linter and the license in use.

Closes #7
Closes #3

configs/*:
Copy all files that do not need a rename generically (not specifying a destination file name).
Do not rename vmlinuz-linux to vmlinuz or vmlinuz.efi (as this serves no purpose and makes the scripts more
complicated).
Do not rename microcode (i.e. {amd,intel}-ucode.img) when copying them and change all boot loader configuration files
that assume a renamed microcode image.
Add note and link to Arch Linux wiki to state why memtest.bin is renamed to memtest.
Copy license files for {amd,intel}-ucode and memtest more generically by placing them into subdirectories with the same
name as the package (to circumenvent overwriting one other).

Closes #33

configs/{baseline,releng}/build.sh:
Copy custom files to airootfs before installing packages.
Instead of calling `mkarchiso init`, list all required packages in packages.x86_64 and install them all at once with `mkarchiso install`. The mkdir command which `mkarchiso init` performs is now done by make_custom_airootfs.

configs/releng/build.sh:
Don't copy configs/releng/pacman.conf to airootfs, it is only meant to provide a unmodified pacman.conf durring pacstrap. In airootfs, an unmodified /etc/pacman.conf will be installed with the pacman package.

Install linux and mkinitcpio packages.
Remove root user's password.

Fixes https://bugs.archlinux.org/task/64236 .

Correct shadow file permissions from build.sh.

When one calls the `build.sh` scripts with bash instead of the shebang
`$script_path` contains the filepath, not the parent dir:

```
% cd /path
% grep -A2 script_path= build.sh
script_path=$(readlink -f "${0%/*}")
echo "$script_path"
exit 0
% ./build.sh
/path
% bash build.sh
/path/build.sh
```

This commit fixes that:

```
% grep -A2 script_path= build.sh
script_path="$( cd -P "$( dirname "$(readlink -f "$0")" )" && pwd )"
echo "$script_path"
exit 0
% ./build.sh
/path
% bash build.sh
/path
```

Timeout is 3 seconds to match systemd-boot's configuration.

Reduce the time where boot loader artifacts linger on screen after the boot loader has done its job.

archiso/mkarchiso:
Quoting all variables.
Changing pkg_list to be an array instead of a string for easier
handling. Using read to properly populate pkg_list from OPTARG with
stripped whitespaces.
Not exporting iso_label anymore as there seems to be no reason to do so.
Introducing line breaks.

.editorconfig:
Setting max_line_length to 120.
Adding a section for YAML files (e.g. .gitlab-ci.yml).

configs/releng/build.sh
Quting nearly all variables.
Introducing line breaks.

configs/baseline/build.sh:
Quoting all variables.
Introducing line breaks.

.gitlab-ci.yml:
Adding gitlab CI for shelleck linting of the config build scripts, mkarchiso and startup scripts in releng.

Closes #19

Always create one filesystem of a fixed size (32G), format (ext4) and
know name "airootfs".

Simplify logic a lot.

Two purposes:
 * systemd filename friendly: "-" is used for "/" and must be escaped with "\x20"
 * ISO9660 filename friendly: "-" is replaced with "_"

* Remove devtools dependency.
* Better control over what files are touched inside chroot (root-image).
  Now: NONE :)
* Two new commands:
  + init: To install {base} group and other needed packages (syslinux for now)
  + run: If we want to run some command inside chroot
         (mkinitcpio, locale-gen, useradd, etc etc...)
* Renamed command: "created" to "install", says much better what does.

Avoid issues with -b BASEDIR (*).

Default (if not specified) -w work -o out.

-o <out_dir> is only used by 'iso' command.
