Factor out equivalent code from ttyread/ttysend

The echo-to-terminal portions of ttyread and ttysend were actually doing
the same thing.  New function twrite() now handles this.  The parameter
show_ctrl determines whether control characters are shown as "^A".  This
was the only difference between tputc and techo, and techo is now unused
and removed.

(This commit should not change st's behaviour.)
