c38503af4d sparc must flush register windows before vm_deallocate or else fireworks 
must deallocate shm's
set/reset emulation environment at the right times
keep arg buffer around for later use
canonicalize all #includes.
support STACKGAP for COMPAT_SUNOS code
support OMAGIC/NMAGIC-style memory loading
don't assume VM_MIN_ADDRESS is 0.
(changes come from magnum branch)

a84055b552 use the ALIGN macro to align the stack, rather than rounding up 
by a (char *).  the former is safe, even on strange machines
(read: sparc).

83aeee1bc0 there now exists an "exec switch". break the a.out code into another 
module, and tidy up the interface so that other object formats are
more easily supportable.

491d6b4b9d fix problem where exec would lose on shell scripts with symlinks in 
their names.  fix from "James W. Dolter" <jdolter@sawtooth.eecs.umich.edu>.
test script:

#!/bin/csh
mkdir /tmp/foodir
cat > /tmp/foodir/testscript <<EOF
#!/bin/sh
echo "Executing script \$1"
EOF
chmod 755 /tmp/foodir/testscript
(cd /tmp ; ln -s foodir foosym)
echo "Trying full path (w/o symlink) to /tmp/foodir/testscript"
/tmp/foodir/testscript "with out symlink"
echo "Trying full path (w/ symlink) to /tmp/foosym/testscript"
/tmp/foosym/testscript "with symlink"
echo "End of Test"

518f7c78d6 a program being exec'd *must* cause *some* exec commands to be invoked; 
if it doesn't there's a problem in the kernel, because a program
with no exec commands run will have no address space except the stack,
and i don't think it's valid to have a "run from stack only" exec type,
so panic.  if need for that case comes up later, it can be changed...

0e6cb953ea ANSIfications - removed all implicit function return types and argument 
definitions.  Ensured that all files include "systm.h" to gain access to
general prototypes.  Casts where necessary.

24fe3e4563 fixed bug where extra spaces at the end of a shell name would 
cause shell scripts to be executed incorrectly.  shells would
receive an *empty* arg for name of script, open it, the kernel
would say "oh, that's ." or something similar, and the results
would be interesting...  found, diagnosed, and killed by me.
