Improve terminal initialisation

Don't just abort() on failures, print a proper error message.

Also, set up ncurses as late as possible.  This should be alright wrt.
signal handlers according to ncurses code, as well as XSI:

> Curses implementations may provide for special handling of
> the SIGINT, SIGQUIT and SIGTSTP signals if their disposition
> is SIG_DFL at the time initscr is called ...

termo blocks job control, so SIGTSTP is not a concern at all.
