Pacman 3 refuses to work with the pacman 4 SigLevel config entry

This build system overhaul allows for adding (define-style) macros to
our scripts. All source files are now suffixed with ".in" to clarify
that they might contain unprocessed defines. The Makefile provides a new
rule to preprocess source files and generate proper output scripts.

Also, add a "@pkgdatadir@" define (as used in GNU Autotools) and use it
instead of hardcoded paths to "/usr/share/devtools" everywhere. We
missed this when adding PREFIX support to the build system in commit
35fc83ce

This is much faster than using Rsync to clone.

Rsync stays available when the chroots are not on a Btrfs.

This prevents accidents when chroots are shared between multiple users.

Archbuild should be called via sudo.

No functional change.

This avoids updating the chroot on every call. See https://bugs.archlinux.org/task/21930

This bypasses a strange pacman behaviour with the --noconfirm parameter.

This will create chroots on demand if needed.
