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.

6e9d047c15 cttyhack: handle multiple consoles found in sysfs 
If multiple consoles are found from the sysfs file, cttyhack fails:

cttyhack: can't open '/dev/tty0 ttyS0': No such file or directory

In such cases take the last one as the kernel will use that one for
/dev/console.

156840c249 cttyhack: print detected ctty name when called without parameters 
Sometimes there's a need to figure out the controlling tty from a shell
script, for example, to obtain a line for getty. In this case it's easier
to call cttyhack than trying to repeat some of the cttyhack's logic.
