Emilio Cobos Álvarez 23e91e805a Bug 1425759: Make Shadow DOM not use XBL anymore. r=smaug,xidorn ...

More improvements to come. In particular, this still iterates through Shadow DOM
in each_xbl_cascade_data, but that should be changed later. That allows to
cleanup a bunch of stuff and finally fix Shadow DOM cascade order.

We still rely on the binding parent to be setup properly in the shadow tree, but
that requirement can go away later (we can walk the containing shadow chain
instead).

This mostly focuses on removing the XBL binding from the Shadow host.

It'd be nice to do EnumerateShadowRoots faster. I think that should also be a
followup, if needed.
