"no" to all parts unfortunately.  the sim/common/ tree is a loose
collection of files.  sims get to opt in to different pieces or simply
re-implement the core functions themselves.  i'd say probably more
than half do.  you can tell quickly by looking at the sub-Makefile and
see how many objects from common it refers to.  and if the sim still
uses "run.c" instead of "nrun.c", you're really screwed.

and from what i recall from when i converted bfin from standalone to
the common tree, the main loops, header files, and state are heavily
impacted.  fairly invasive to convert over, but much of it is simply
code massage rather than rewriting new stuff.

the upside is that the conversion tends to involve throwing out a lot
of code because common/ takes care of it for you.  the downside is
that it isnt trivial, and i unfortunately have no interest in
converting other sims.
