This implements Package API v2.0, and is an opt-in feature for repos. It can be enabled with
```yaml
repo:
...
api: v2.0
```
It differs from the current default v1.0 as follows:
1. Package names can only contain `-` as a separator.
2. Package names can only be lowercase.
3. Package directory names are valid Python module names.
4. The repo namespace and its directory name are the same.
5. The `packages` subdir, which is configurable, should be a directory
name that is also a valid Python module name.
6. There is a one to one mapping between Spack package names and Python
module names.
7. Import statements `import spack.pkg.namespace.package_module` in
`package.py` files need to specify the canonical package module.
To go from Spack package name to Python module name:
- Replace `-` by `_`
- Add a leading `_` if the package name starts with a digit
To go from Python module name to Spack package name:
- Strip leading `_`
- Replace `_` by `-`.

Fix to cpup for zone grid connectivity. Previous versions broken for some meshes.
Database entity names (sets, blocks) are not lowercased by default.

* zoltan: add scotch library dependency
Due to the way the shared library is built it does not pick up
dependencies to other shared libraries correctly. This adds the library
dependency manually in the same way it is already done for parmetis.
* add tukss as maintainer for zoltan
