reactos/dll/win32/kernel32/client/console/readwrite.c
Hermès Bélusca-Maïto 22c9e139a1 [KERNEL32][CONSRV] 
- Make kernel32 / winsrv console CSR structures Win2k3-compliant for Read/WriteConsole functions.
  An attentive code reader will see that there are structure members in CONSOLE_WRITECONSOLE that are
  indeed unused by kernel32 that can be used in ReactOS for undocumented extensions of WriteConsole...
  (for instance, adding a parameter for ANSI codes support, who knows!... :P)
- Fix a bit the support for the CONSOLE_READCONSOLE_CONTROL parameter in ReadConsole (for unicode only).
- Use the actual exe name for command history management, given via a hackish way by ReadConsole:
  the exe name is passed via the 80-byte-length limited static buffer, and is of course retrieved before
  actually using the static buffer (if needed).

[CONSRV]
- Fix writing input events in the console, but first preprocessing them for pausing commands (we treat them separately and remove them),
  then, in case we write many single events, we merge them in case they are mouse moves or repeated key down presses. This helps in not
  overflowing too quickly the input buffer, and that fixes all the remaining kernel32:console winetests!! (see CORE-8256)
- Use the actual exe name for command history management, given via a hackish way by ReadConsole (blame MS!)
