* gperftools@2.7: new version
* gperftools: update homepage & url
The URL in the homepage field of the gperftools package redirects to
its GitHub repo, and the URL for version 2.3 returns a 404 error. This
commit updates both fields to the most recent sensible values.
* gperftools: update commit hashes to sha256
This commit deletes the url field for all listed versions because it
is no longer needed as a result of updating the package url field. In
addition, all commit hashes are updated to SHA256.
- 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
Package repositories now look like this:
top-level-dir/
repo.yaml
packages/
libelf/
package.py
mpich/
package.py
...
This leaves room at the top level for additional metadata, source,
per-repo configs, indexes, etc., and it makes it easy to see that
something is a spack repo (just look for repo.yaml and packages).
