[RFC/PATCH 00/10] Support using submodules with worktrees

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Since this topic has come up twice recently, I'll take this opportunity
to gather early comments on this series. It depends nd/config-move-to and
at least has one known problem reported Tomasz. But I'll fix that
later once nd/config-move-to lands.

For more details, head for 01/10. This basically makes it possible
to create secondary worktrees in either supermodules or submodules. The
user will be required to turn on extensions.worktreeConfig and this is
something I'll need to work on, to make the transition smoother.

Note that while it works, it's not really optimal because worktree
clones of the same submodule could be duplicated. But hopefully I could
tackle this one step at a time. Make it work first, shake out bugs, then
think about sharing repos.
