2f1e635b9d ti84: tidy up driver code
Pushed all words directly interfacing with ports and memory offsets to
low level layers. This saves us the need for keeping those variables in
runtime memory.

baf725aa38 Move a bunch of words from core to inner core
That makes it easier to write drivers that can be xcompiled.

Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.

58ece9f9a1 editor: implement I command
Also, made LIST properly handle full 64-chars lines not ending with
a null or CR. Previously, such a line would be accompanied by its
following line, duplicating that line's output.

31119c2de3 xcomp: move all offset spitting to the end of the unit
I'd like to move this code, along with all recipe contents, to blk/.
It's easier if "emul-related" code is gathered at the same place.

fa79e3d8a6 Make (print) stop on CR
Lines edited with the Block editor end with 0xd and (print) spits
spurious CR when printing those lines.

Also, properly initialize ACC in BROWSE.
