96265e088e Remove the printf builtin command from sh(1), which command is not
used so often that it's worth keeping it as a builtin.

Now that all the printf invocations from within the system startup
scripts, we can safely remove it.

Urged by:	sheldonh  :)

No MFC is planned so far because it may break compatibility and
violate POLA.

b58a3e4078 Make test(1) a builtin command of our sh(1) for efficiency. The
binary size increase is 3,784 bytes (about 0.6%).

I don't drop the printf builtin while I'm here because some /etc/rc.*
scripts seem to use it before mounting /usr where printf(1) resides.

ee151afe78 Fix child's SIGSTOP behaviour in scripts.
When a child is receiving SIGSTOP, eval continues with the next
command.  While that is correct for the interactive case (Control-Z
and you get the prompt back), it is wrong for a shellscript, which
just continues with the next command, never again waiting for the
stopped child.  Noted when childs from cronjobs were stopped, just to
make more processes (by wosch).

The fix is not to return from a job wait when the wait returned for a
stopped child while in non-interactive mode.  This bahaviour seems to
be what bash2 and ksh implement.  I tested for correct behaviour for
finnaly killing the child with and without forgrounding it first.
When not foregrouding before killing, the shell continues with the
script, which is what the other shells do as well.
