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.

It's not possible to type Ctrl+Space (aka ^@) into the CMD.EXE
|

console. Ctrl+Z is also problematic, since the Windows Console
|
||||
processes that keystroke into an EOF event, even when we don't
|
||||
enable input processing. These control codes are important for
|
||||
Emacs users. One solution is to install the "Windows Terminal"
|
||||
application from Microsoft Store, type Ctrl+Shift+, to get its
|
||||
settings.json file opened, and add this code to its "actions":
|
||||
|
||||
"actions": [
|
||||
{
|
||||
"command": {
|
||||
"action": "sendInput",
|
||||
"input": "␀"
|
||||
},
|
||||
"keys": "ctrl+space"
|
||||
},
|
||||
{
|
||||
"command": {
|
||||
"action": "sendInput",
|
||||
"input": "␚"
|
||||
},
|
||||
"keys": "ctrl+z"
|
||||
},
|
||||
{
|

"command": {
|

"action": "sendInput",
|
||||
"input": "\u001f"
|
||||
},
|
||||
"keys": "ctrl+-"
|
||||
}
|
||||
],
|
||||
|
||||
Its not possible to configure Windows Terminal to output our
|
||||
control codes. The workaround is to encode control sequences
|
||||
using the "Control Pictures" UNICODE plane, which we'll then
|
||||
translate back from UTF-8 glyphs, into actual control codes.
|
||||
|
||||
Another option Windows users can consider, particularly when
|
||||
using CMD.EXE is installing Microsoft PowerTools whech makes
|
||||
it possible to remap keys then configure ncurses to use them
