Rewrite Windows console input handling

Browse source 
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.
