Will there be refactoring support in the near future?
Not in the near future. We're missing multi-translation unit IntelliSense, which is a required component for refactoring to work across translation units.
I think we already have issues tracking this so I'll close this one: https://github.com/Microsoft/vscode-cpptools/issues/296, https://github.com/Microsoft/vscode-cpptools/issues/1162
