[REACTOS]

Fix spelling of 'length' in various places.
Patch by andygui

Concerning kdio.c, we can see that the original author didn't see his misspelling since he used two different variables named:
KdpScreenLineLength and KdpScreenLineLenght ! ; the latter being renamed here KdpScreenLineLengthDefault to make the difference.
