Todd Gamblin c615d2be06 init: move spack.repo global variable into its own module ...

- spack.repository module is now spack.repo

- `spack.repo` is now `spack.repo.path()` and loaded lazily

- Added `spack.repo.get()` and `spack.repo.all_package_names()` as
  convenience functions to simplify the new lazy interface.

- updated tests and code
