StripCtrlChars: retarget and reset functions.

Browse Source 
stripctrl_retarget() points the StripCtrlChars at a new BinarySink, to
avoid having to pointlessly throw it away and make a new one all the
time.

Since that probably means the same scc is going to be reused for
processing a fresh data stream, we also don't want any character-set
conversion state hanging over from the previous stream, so we also
reset the state in the process. Just in case it's needed,
stripctrl_reset() is also provided to do that operation on its own.
