Summary: As suggested in D48796, this patch replaces even more internal calls that were using the old completion API style with a single CompletionRequest. In some cases we also pass an option vector/index, but as we don't always have this information, it currently is not part of the CompletionRequest class. The constructor of the CompletionRequest is now also more sensible. You only pass the user input, cursor position and your list of matches to the request and the rest will be inferred (using the same code we used before to calculate this). You also have to pass these match window parameters to it, even though they are unused right now. The patch shouldn't change any behavior.
