reactos/win32ss/user/consrv/guiconsole.c
Hermès Bélusca-Maïto 0473031b87 [KERNEL32] 
- Move console-related Vista+ functions from client/vista.c to a dedicated client/console/vista.c file, and add it to compilation.
- Move some helper functions from console.c to history.c.
- Use the new api index names in history.c.

[CONSRV]
- Merge CSRSS_GET_HISTORY_INFO and PCSRSS_SET_HISTORY_INFO structures declarations into CSRSS_HISTORY_INFO, and therefore use only one member of it inside CONSOLE_API_MESSAGE structure.
- WORD --> UINT for few structure members related to history information.
