Subject: create new machine/_float.h which is namespace clean.  create a new
 MI float.h which pulls in and defines the values that are needed from there,
 and repair sys/limits.h so that it defines the values it needs as well
 (depending on POSIX version, XPG version, etc).  guenther has a more exact
 selection of that coming for limits.h. this also fixes a few mistakes for the
 vax. reviewed by kettenis and guenther.
