If a manifest top level directory contains '.gitmodules' we now
assume this is a git module format manifest and switch to using
that code, rather than the legacy XML based manifest.
At the same time, we move the bare repository for a project from
$TOP/.repo/projects/$REPO_PATH.git to be $REPO_NAME.git instead.
This makes it easier for us to later support a repo init from an
existing work tree, as we can more accurately predict the path of
the project's repository in the workspace. It also means that the
$TOP/.repo/projects/ directory is layed out like a mirror would be.

If the caller knows exactly what the manifest type must be we
can now ask the loader to directly construct that type, rather
than guessing it from the working directory.
