Merge branch 'mplegendre-multi_pkgsrc_roots' into develop
- This moves var/spack/packages to var/spack/repos/builtin/packages. - Packages that did not exist in the source branch, or were changed in develop, were moved into var/spack/repos/builtin/packages as part of the integration. Conflicts: lib/spack/spack/test/unit_install.py var/spack/repos/builtin/packages/clang/package.py
