obsolete: don't use os.stat in repo.obsstore.__nonzero__ if it's static HTTP
If a repo is accessed via static HTTP, then we obviously can't use os.stat() to
just peek at the file size. Let's download the entire file to check its size.
Yes, this feels wasteful, but:
1. If we're cloning or pulling a repo from a static HTTP server, we need the
contents of the obsstore anyway.
2. Implementing statichttpvfs.stat() that uses HEAD will result in one more
request to a static-only HTTP server, which is already slow. Also parsing a
response to a HEAD request to construct os.stat_result is pretty hacky.
There's also a question of the remote server properly supporting HEAD method
and reporting at least file size.
3. Implementing statichttpvfs.stat() that uses GET is pretty much the same
thing as we do here, except we can't even cache the response easily, unlike
simply accessing obsstore._data, which is @propertycache'd.
Importing statichttprepo locally to avoid circular import.
