5cb907fffc setconsole: make it NOEXEC 
BTW, I failed to make it do what it meant to do.
ioctl appears to succeed, but kernel's output is not coming
to the specified console (tried on VT consoles too).
OTOH, setlogcons does work...

5c527dc57e make 17 state-changing execing applets (ex: "nice PROG ARGS") noexec 
The applets with "<applet> [opts] PROG ARGS" API very quickly exec
another program, noexec is okay for them:

 chpst/envdir/envuidgid/softlimit/setuidgid
 chroot
 chrt
 ionice
 nice
 nohup
 setarch/linux32/linux64
 taskset
 cttyhack

"reset" and "sulogin" applets don't have this form, but also exec
another program at once, thus made noexec too.
