Separate root-related code

This creates a root.c and moves bits and pieces from elsewhere into it.

* layout_init has been renamed to root_create and moved into root.c
* root_destroy has been created and is called on shutdown
* scratchpad code has been moved into root.c, because hidden scratchpad
containers are stored in the root struct
