Rebase one path to another path.
Give a absolute file path and folder path, and compute the relative path of given file to given folder.
Then applied the computed relative path to another given folder path.
Thus it seems like the file was rebased to from a folder to another folder with keeping the folder hierarchy.
For example, given `/path/to/file` and `/path`, it will compute relative path `to/file`.
Then it was applied to another folder path `/new` and got `/new/to/file`.
