Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html

Rewrite Windows console input handling 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.
