Log Message:
Fix curses CPU spin when PTY is deleted (ticket #216)
When a ttyd/SSH session drops and the PTY is deleted, ioctl(FIONREAD)
returns -1/EIO instead of 0. The EOF detection in curs_getch() only
checked for ioctl()==0, so the EIO case was missed and the while(get_wch()==ERR) loop spun at ~100% CPU. Treat FIONREAD failure
as a dead fd and return CIO_KEY_QUIT immediately.
