Switch gen-kconfig to new framework

Also:
- Move companion_* to comp_* to match the kconfig symbols
- Replace bootstrap with former gen-versions.sh
- Fold *.in.2 into their respective first parts; this moves common
  options to the end - if it is undesirable, inclusion of *.in
  can be moved where *.in.2 used to be (but that will also move
  version selection after common options).
- Retire addToolVersion.sh (may later replace with a more
  comprehensive script that tries to download the added tarballs,
  copy the patches and try to apply them, and create a version.desc).
