1991a464bd core: add Workspace back in 
The Workspace turns out to be useful, particularly when handled
correctly. This allows for a unification of all packages.

Additionally, since we now are focusing on applications and servers now,
the decision of which packages to build by default becomes clearer.

Finally, we'll be able to use `xbuild` to construct more complex
workflows with a full Workspace.

bb17038bfe kernel: rename "xous" to "xous-kernel" in import 
Cargo appears to cache packages in the workspace when multiple packages
use the same crate. Unfortunately, Xous uses different features
depending on whether it's running in the kernel or in userspace.

Pull the kernel version of "xous" in under a different namespace in
order to force it to use a different build.
