[archiso] Use dm-snapshot instead of aufs2 (A.K.A. "The Big Commit")

* Use device mapper + snapshot module, instead union layer filesystem.
  * A block-level approach vs vfs-level.
  * No more unofficial (Linux) things.
  * More memory is needed.
* Refactor mkarchiso.
* Refactor hooks/archiso.
* Fix install/archiso_pxe_nbd
  (due recent change in mkinitcpio-0.6.15 on checked_modules()/all_modules())
  [Thanks Dave for the improved workaround]
* New configs/releng to build official images.
  * Works with a Bash script instead of Makefile.
    (better control and easy to maintain)
* Remove configs/syslinux-iso.
* Remove archiso2dual script. Integrate functionality in configs/releng.
* New configs/baseline to build the most basic live medium or use as template.
* New README (draft). [Thanks Dieter for fixing english grammar]
