Can we cache the result of getCompletion() with a variable outside the for loop? The implementation of getCompletion is pretty complex in org.eclipse.jdt.internal.codeassist.InternalCompletionProposal and calling it in each iteration looks expensive.

Can we use the SortTextHelper.CELING for consistency?
Its value is 999_999_999.

TextEdits need to be computed during the completion call, but this can be extremely slow when a large number of results is returned. This change tries to mitigate the issue by returning a partial result list and marking the results as incomplete. Smaller payload means computing Textedits is now more affordable. Hopefully the UX should be improved as well since completion queries will return faster too. The number of completion results is configurable with the java.completion.maxResults preference (defaults to 50). Setting 0 will disable the limit and return all results. Be aware the performance will be very negatively impacted as textEdits for all results will be computed eagerly (can be thousands of results).
