move new interpreter class to separate file
* libinterp/corefcn/interpreter.cc, libinterp/corefcn/interpreter.h:
New files. Move interpreter class and some supporting functions here
from octave.h, octave.cc, toplev.h, and toplev.cc. Move main_loop
into the interpreter class. Handle exiting with a separate exception
object from interrupts, passing the exit status with the object.
Update other files as needed to remove toplev.h or include
interpreter.h instead of toplev.h.
* libinterp/corefcn/module.mk: Update.
* toplev.h: Deprecate.
