Inline the stats printf calls to avoid compiler warnings about
non-literal format strings.  This in turn highlights bad type
sizes being passed in, so fix the strings to use the right size
type.  This in turn highlights the rest of the func using casts
rather than the right type directly, so adjust all of those.

Finally, replace a few abort+sim_engine_halt calls with the
common sim_engine_abort.  This provides good output while still
aborting as we want.
