term: implement cursor blinking

Browse source 
Blinking can be enabled either by setting the cursor style with

 CSI Ps SP q

and selecting a blinking style.

Or, with 'CSI ? 12 h'

Note that both affect the same internal state. I.e. you can disable
blinking with CSI ? 12l after having selected a blinking cursor
style. This is consistent with XTerm behavior.
