d6c2830850
This change removes our use of ENABLE_VIRTUAL_TERMINAL_INPUT (which isn't very good) in favor of having read() translate Windows Console input events to ANSI/XTERM sequences by hand. This makes it possible to capture important keystrokes (e.g. ctrl-space) that weren't possible before. Most importantly this change also removes the stdin/sigwinch worker threads, which never really worked that well. Interactive TTY sessions will now work reliably when a Cosmo process spawns or forks another Cosmo process, e.g. unbourne.com launching emacs.com.
