z_overlay and z_fbdemo_dlftbls (Transition overlay handling), clean up a lot of u32s used to store pointers (#1073)

* overlay matches

* prototypes

* fbdemo too

* virtual to physical

* names, cleanup, etc

* bss reordering

* uintptr stuff

* fixed now?

* one fix

* headers and such

* fixes'n'stuff

* XXX action

* docs of a sort

* useless error codes

* n

* format

* header? I barely know her!
