Log:
[CONSRV]
- Move SrvSetConsoleWindowInfo to a better place.
- When enlarging the console buffer, use the attributes of the last cell of each line to
fill the new cells for each line.
- Remove usage of HAVE_WMEMSET / wmemset for resizing the buffer (NOTE: maybe it will be
needed again later on...)
