Changes to deal with the fact that the 386 does not honor read-only pages
for kernel accesses.  Make subyte and suword check for write permission
and simulate a page fault if necessary.  copyout requires similar
treatment, for now, it is in C in trap.c.  Also, check for valid user
addresses in all of the functions that move data to and from the user
address space.  Delete functions for moving shorts (fusword, susword),
which are not used.  Finally, add a push for the environment pointer which
was missing from the call to exec in icode; from Pace Willisson.
