Juan RP 0d68a49660 Multiple changes in the infrastructure for improving the (un)stow stuff.
- Added pre_remove/post_remove/post_stow support for templates.

- When stowning pkgs, symlink all files into the chroot. This only works
  for packages that need to be built on it, also templates that set
  stow_copy will copy its files, or selectively via stow_copy_files.
