Since this PR is very large and not covered by CI tests, it is hard to take it directly into the main branch, i.e. I could not read every line to make sure it doesn't break anything or rely on the test cases to make sure the features introduced will not be broken.

To accelerate the development process, I changed the base to a different branch demo. Please merge related improvements to that branch, and we will merge it whenever it has been thoroughly tested.
