Log:
[CONSRV]
- Call TermGetLargestConsoleWindowSize to obtain the largest console window size allowed
on the system, and use it for GetConsoleScreenBufferInfo and for SetConsoleWindowInfo too,
where it is used to check if the given user window size is not too large.
- Improve GuiGetLargestConsoleWindowSize for multi-monitor situations.
- Remove the redundant definition of GetScreenBufferSizeUnits in guiterm.c (it already
exists in conwnd.c).
