nethack/sys/windows/consoletty.c
nhmall 92340a6827 consolidate some arg processing 
Unix and Windows had diverged significantly for command line
options handling.

This:
   1. uses the the Unix processing as a baseline.
   2. consolidates the code in earlyarg.c, where it can
      be a common copy to be shared.
   3. start converting the Windows command line argument
      processing to the Unix code that now resides in earlyarg.c.

* Console Buffer Flipping Support
*
* To minimize the number of calls into the WriteConsoleOutputXXX methods,
* we implement a notion of a console back buffer which keeps the next frame
* of console output as it is being composed. When ready to show the new
* frame, we compare this next frame to what is currently being output and
* only call WriteConsoleOutputXXX for those console values that need to
* change.

/*
* Keystroke handling contributed by Ray Chason.
* The following text was written by Ray Chason.
*
* The problem
* ===========
*
* The console-mode Nethack wants both keyboard and mouse input. The
* problem is that the Windows API provides no easy way to get mouse input
* and also keyboard input properly translated according to the user's
* chosen keyboard layout.
*
* The ReadConsoleInput function returns a stream of keyboard and mouse
* events. Nethack is interested in those events that represent a key
* pressed, or a click on a mouse button. The keyboard events from
* ReadConsoleInput are not translated according to the keyboard layout,
* and do not take into account the shift, control, or alt keys.
*
* The PeekConsoleInput function works similarly to ReadConsoleInput,
* except that it does not remove an event from the queue and it returns
* instead of blocking when the queue is empty.
*
* A program can also use ReadConsole to get a properly translated stream
* of characters. Unfortunately, ReadConsole does not return mouse events,
* does not distinguish the keypad from the main keyboard, does not return
* keys shifted with Alt, and does not even return the ESC key when
* pressed.
*
* We want both the functionality of ReadConsole and the functionality of
* ReadConsoleInput. But Microsoft didn't seem to think of that.
*
*
* The solution, in the original code
* ==================================
*
* The original 3.4.1 distribution tries to get proper keyboard translation
* by passing keyboard events to the ToAscii function. This works, to some
* extent -- it takes the shift key into account, and it processes dead
* keys properly. But it doesn't take non-US keyboards into account. It
* appears that ToAscii is meant for windowed applications, and does not
* have enough information to do its job properly in a console application.
*
*
* The Finnish keyboard patch
* ==========================
*
* This patch adds the "subkeyvalue" option to the defaults.nh file. The
* user can then add OPTIONS=sukeyvalue:171/92, for instance, to replace
* the 171 character with 92, which is \. This works, once properly
* configured, but places too much burden on the user. It also bars the
* use of the substituted characters in naming objects or monsters.
*
*
* The solution presented here
* ===========================
*
* The best way I could find to combine the functionality of ReadConsole
* with that of ReadConsoleInput is simple in concept. First, call
* PeekConsoleInput to get the first event. If it represents a key press,
* call ReadConsole to retrieve the key. Otherwise, pop it off the queue
* with ReadConsoleInput and, if it's a mouse click, return it as such.
*
* But the Devil, as they say, is in the details. The problem is in
* recognizing an event that ReadConsole will return as a key. We don't
* want to call ReadConsole unless we know that it will immediately return:
* if it blocks, the mouse and the Alt sequences will cease to function
* until it returns.
*
* Separating process_keystroke into two functions, one for commands and a
* new one, process_keystroke2, for answering prompts, makes the job a lot
* easier. process_keystroke2 doesn't have to worry about mouse events or
* Alt sequences, and so the consequences are minor if ReadConsole blocks.
* process_keystroke, OTOH, never needs to return a non-ASCII character
* that was read from ReadConsole; it returns bytes with the high bit set
* only in response to an Alt sequence.
*
* So in process_keystroke, before calling ReadConsole, a bogus key event
* is pushed on the queue. This event causes ReadConsole to return, even
* if there was no other character available. Because the bogus key has
* the eighth bit set, it is filtered out. This is not done in
* process_keystroke2, because that would render dead keys unusable.
*
* A separate process_keystroke2 can also process the numeric keypad in a
* way that makes sense for prompts: just return the corresponding symbol,
* and pay no mind to number_pad or the num lock key.
*
* The recognition of Alt sequences is modified, to support the use of
* characters generated with the AltGr key. A keystroke is an Alt sequence
* if an Alt key is seen that can't be an AltGr (since an AltGr sequence
* could be a character, and in some layouts it could even be an ASCII
* character). This recognition is different on NT-based and 95-based
* Windows:
*
* * On NT-based Windows, AltGr signals as right Alt and left Ctrl
* together. So an Alt sequence is recognized if either Alt key is
* pressed and if right Alt and left Ctrl are not both present. This
* is true even if the keyboard in use does not have an AltGr key, and
* uses right Alt for AltGr.
*
* * On 95-based Windows, with a keyboard that lacks the AltGr key, the
* right Alt key is used instead. But it still signals as right Alt,
* without left Ctrl. There is no way for the application to know
* whether right Alt is Alt or AltGr, and so it is always assumed
* to be AltGr. This means that Alt sequences must be formed with
* left Alt.
*
* So the patch processes keystrokes as follows:
*
* * If the scan and virtual key codes are both 0, it's the bogus key,
* and we ignore it.
*
* * Keys on the numeric keypad are processed for commands as in the
* unpatched Nethack, and for prompts by returning the ASCII
* character, even if the num lock is off.
*
* * Alt sequences are processed for commands as in the unpatched
* Nethack, and ignored for prompts.
*
* * Control codes are returned as received, because ReadConsole will
* not return the ESC key.
*
* * Other key-down events are passed to ReadConsole. The use of
* ReadConsole is different for commands than for prompts:
*
* o For commands, the bogus key is pushed onto the queue before
* ReadConsole is called. On return, non-ASCII characters are
* filtered, so they are not mistaken for Alt sequences; this also
* filters the bogus key.
*
* o For prompts, the bogus key is not used, because that would
* interfere with dead keys. Eight bit characters may be returned,
* and are coded in the configured code page.
*
*
* Possible improvements
* =====================
*
* Some possible improvements remain:
*
* * Integrate the existing Finnish keyboard patch, for use with non-
* QWERTY layouts such as the German QWERTZ keyboard or Dvorak.
*
* * Fix the keyboard glitches in the graphical version. Namely, dead
* keys don't work, and input comes in as ISO-8859-1 but is displayed
* as code page 437 if IBMgraphics is set on startup.
*
* * Transform incoming text to ISO-8859-1, for full compatibility with
* the graphical version.
*
* * After pushing the bogus key and calling ReadConsole, check to see
* if we got the bogus key; if so, and an Alt is pressed, process the
* event as an Alt sequence.
