reason for not using remote servers in the layout.

Some git state is further split out under `project-objects/`.
* `project-objects/`: Git objects that are safe to share across multiple
git checkouts. The filesystem layout matches the `<project name=...`
setting in the manifest (i.e. the path on the remote server). This allows
for multiple checkouts of the same remote git repo to share their objects.
For example, you could have different branches of `foo/bar.git` checked
out to `foo/bar-master`, `foo/bar-release`, etc... There will be multiple
trees under `projects/` for each one, but only one under `project-objects/`.

This can run into problems if different remotes use the same path on their
respective servers ...
This layout is designed to allow people to sync against different remotes
(e.g. a local mirror & a public review server) while avoiding duplicating
the content. However, this can run into problems if different remotes use
the same path on their respective servers. Best to avoid that.
* `subprojects/`: Like `projects/`, but for git submodules.
* `subproject-objects/`: Like `project-objects/`, but for git submodules.
* `worktrees/`: Bare checkouts of every project synced by the manifest. The

same advantages as the `project-objects/` layout above.
This is used when git worktrees are enabled.
