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`.

Summary:
Before I implement a proper fix [1], let's just use the correct slashes.
[1]
Correct fix is de-verbatimization of canonicalized paths.
So, if `a-symlink->b` and `"C:\a".canonicalize()` produces `\\?\C:\b`, then doing `.push("c/d")` produces `\\?\C:\b\c/d`, where `c/d` is a *single* path component, becuase the path starts with `\\?\`. If there isn't such prefix, it's fine to push forward-slash-separated things into Windows paths.

Summary:
We need to canonicalize `current_exe` to resolve symlinks on OSX.
Unfortunetely, on there's no way to just resolve symlinks and not
turn path into a `\\?\` on Windows, AFAIK.
Once the path is canonicalized on Windows, it starts with `\\?\` and
forward slashes are no longer recognized as valid separators.
Here's a demonstration:
```
> cat src\main.rs
use std::path::Path;
fn main() {
let p = Path::new("\\\\?\\C:\\Code\\fbsource\\fbcode\\scm\\hg\\mercurial/entrypoint.py");
for comp in p.components() { println!("{:?}", comp); }
println!("{:?} exists: {}", p, p.exists());
let p = Path::new("\\\\?\\C:\\Code\\fbsource\\fbcode\\scm\\hg\\mercurial\\entrypoint.py");
for comp in p.components() { println!("{:?}", comp); }
println!("{:?} exists: {}", p, p.exists());
let p = Path::new("C:\\Code\\fbsource\\fbcode\\scm\\hg\\mercurial/entrypoint.py");
for comp in p.components() { println!("{:?}", comp); }
println!("{:?} exists: {}", p, p.exists());
}

Summary:
This is important on OSX where `current_exe` will return the symlink address if `hg.rust` is a symlink.
Therefore, if you create a symlink to the `hg.rust` in the repo (like tests do), repo Python code won't be picked up, and the system code will be.

Following the conversation with quark-zju, this in future will help us conditionally dynamically load
the `hgpython` `.dll`/`.so` only if we need it.
