Refactor interface between backend and frontend (#530)

Browse Source 
* Rename to use Config, rather than StateHandle/Globals/Backend
* Make Backend a type on Config that contains the address space management implementation
* Make Ranges part of the Backend configuration, so we can reuse code for different ways of managing memory
* Pull the common chains of range definitions into separate files for reuse.
* Move PagemapEntry to CommonConfig
* Expose Pagemap through backend, so frontend doesn't see Pagemap directly
* Remove global Pal and use DefaultPal, where one is not pass explicitly.
