Summary: Move top-level Python packages `mercurial`, `hgext` and `hgdemandimport` to a new top-level package `edenscm`. This allows the Python packages provided by the upstream Mercurial to be installed side-by-side. To maintain compatibility, `edenscm/` gets added to `sys.path` in `mercurial/__init__.py`.
