Jun Wu c12e300bb8 codemod: move Python packages to edenscm
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`.
