syl20bnr dc58801c7d core: refactor shadow mechanism
Shadowing is now control by layer property ':can-shadow' only.
can-shadow is a commutative relation, if layer1 can shadow layer2 then layer2
can shadow layer1.
the shadow operator is a binary operator accepting two layer names, it is not
commutative and the order of the operands is determined by the order of the
layers in the dotfile (like the ownership stealing mechanism).

If ':can-shadow' is set explicity to nil in the dotfile then the layer won't
shadow any layer.
For instance to install both ivy and helm layer:

   (setq dotspacemacs-configuration-layers
   '(
     ivy
     (helm :can-shadow nil)
     )

note that due to the commutative relation the above example can also be
written (in this case, ':can-shadow' should be read ':can-be-shawdowed'):

   (setq dotspacemacs-configuration-layers
   '(
     (ivy :can-shadow nil)
     helm
     )
