scmutil: introduce function to check whether repo uses treemanifest or not In an upcoming patch, I wanted to check whether current repo uses treemanifest or not. I looked for a function and found that at all places we manually check for the requirement in repo requirements. I guess having a dedicated function for that is much better.
