- Parse all paths with realpath. Fixes #84 .

configs/releng: move the mirror uncommenting sed command from customize_airootfs.sh to a pacman hook

After pacman-mirrorlist is installed, /etc/pacman.d/hooks/uncomment-mirrors.hook will run a sed command which uncomments all Server lines in /etc/pacman.d/mirrorlist.
This brings us another step closer to the complete removal of customize_airootfs.sh.

Related to #21 .

Booting via PXE we want to keep our DNS configuration. So remove
/etc/resolv.conf in new root before copying the current file.

Without this systemd-resolved fallback nameservers are used and we see an
error message when the root ships a symbolic link to systemd-resolved's
stub-resolv.conf:

cp: not writing through dangling symlink '/new_root/etc/resolv.conf'

To date the iso version was used for iso volume information and iso file name.
In my custom builds I do use it a lot more:

* Inside the root fs: The system knows about its own version. I use this to:
  -> report the version to a server (poor man's inventory)
  -> let the system update itself

* On the iso fs: The files are served via rsync, running systems transfer
  version file first to check for available update.

* A grub environment file on the iso fs: Booting the iso from grub allows
  to create cow directory per version:

    loopback loop archlinux.iso
    load_env -f (loop)/arch/grubenv
    linux (loop)/arch/boot/x86_64/vmlinuz-linux ... \
        cow_directory=archlinux/${VERSION} ...

So let's just create these files.

Usage: Launch run_archiso.sh -v ..., and then use a VNC viewer
(e.g. from https://wiki.archlinux.org/index.php/List_of_applications/Internet#Remote_desktop)
to connect (typically to `localhost`) on the default VNC port (5900).

This enables using run_archiso in a "headless" session; e.g. when SSH logged in
to the CLI of a VM, without a local display attached.  This is handy e.g. when
playing https://en.wikipedia.org/wiki/Inception and running an archlinux*.iso
on any non-Arch (say Fedora workstation), on which one built a new ISO, that you
then "run_archiso", inside which you could build another ISO, which you could
itself start inside the nested VM... ;-)

Jokes apart, this could also be used to run automated CI/CD tests of the built ISO,
which is particularly interesting in combination with the cloud-init support;
see https://wiki.archlinux.org/index.php/Cloud-init.

Fixes https://bugs.archlinux.org/task/68803 .

archiso/mkarchiso:
Make sure to always compare absolute paths in `_make_custom_airootfs()` (as `realpath` is used).
Remove `echo` calls that prevent the setting of actual file ownerships and modes.

configs/releng/profiledef.sh:
Set file mode of /root/.automated_script.sh to 755.

Fixes #82

This gets rid of the duplicate ldlinux.c32 and the useless isolinux.cfg which only points to syslinux.cfg.

Implements archlinux/archiso#46 .

profiledef.sh can now contain an associative array called file_permissions which can be used to set custom ownership and mode of custom airootfs files. The array's keys contain the path and the value is a colon separated list of owner UID, owner GID and access mode.
For example:

    file_permissions=(
      ["/etc/shadow"]="0:0:400"
    )

This means that mkarchiso now copies airootfs files (and directores) without permissions and anything that should be owned by a user other than root and/or if the mode should be something other than 644 for files and 755 for directories must to be listed in ${file_permission[@]} in profiledef.sh.

Fixes archlinux/archiso#61 .

archiso/mkarchiso:
Guard the call to `_mksignature()` in `_prepare_airootfs_image()` by an if statement.
Using the `&&` logic leads to `_prepare_airootfs_image()` evaluating to false if `$gpg_key` is not set.

Add `_msg_info()` calls to `_set_override()` which prevent the function from evaluating to false if no override is
being done. Additionally this is great for debugging purposes.

Add `_msg_info()` calls to `_read_profile()` (which is great for debugging purposes).

Fixes #81

archlinux/base is being deprecated anyway.

mkarchiso: add xorrisofs options from boot mode specific functions instead of hardcoding them in _build_iso

Fixes #76 .

- Remove remnants of the now removed legacy commands.
- Improve readability by getting rid of some "if" statements when performing string comparisons.
- Rename functions to make their purpose more clear.
- Move some conditions from functions to their invocations.

Default: 732M
With these options: 675M

- fatresize is a utility to resize FAT filesystems using libparted.
- gpart is partition table rescue/guessing tool.
- tmux is a terminal multiplexer. Requested in https://bugs.archlinux.org/task/68252 .

configs/releng/syslinux/archiso_sys.cfg:
Set the syslinux bootloader timeout to 15s.
In !97 it has accidentally been set to 1.5s.

configs/releng/efiboot/loader/loader.conf,
configs/releng/syslinux/archiso_sys.cfg:

Set the bootloader timeout to 15s, as they have been set to an overly generous 30s in !79.

Fixes #80

scripts/run_archiso.sh:
Add the `-a` option flag to add accessibility support on demand for `run_archiso`.

Add accessibility specific options to qemu in `run_image()`.

Not providing the specific braille chardev hardware otherwise blocks running run_archiso with
`qemu-system-x86_64: -chardev braille,id=brltty: brlapi__openConnection: connect: No such file or directory`.

Fixes #77

configs/releng/airootfs/usr/local/bin/livecd-sound:
Replace oldstyle expr with a bash test in `is_numeric()`.

Replace use of `nword()` with call to `wc -w`.

Quote variables in `pick_a_card()`.

Fixes #78
