Withdraw support for the DECEDM escape sequence.

Browse Source 
Having decided that the terminal's local echo setting shouldn't be
allowed to propagate through to termios, I think the local edit
setting shouldn't either. Also, no other terminal emulator I know
seems to implement this sequence, and if you enable it, things get
very confused in general. I think it's generally better off absent; if
somebody turns out to have been using it, then we'll at least be able
to find out what it's good for.
