cflinuxfs2 rootfs Support

Cloud Foundry is releasing new versions of go, nodejs php,
python, and ruby buildpacks to support cflinuxfs2, which is
the official name of the trusty64-based rootfs (or "stack").

Please note that the previous lucid64 stack is also supported by
this buildpacks release.

In order to support multiple stacks, we've extended the data structure
represented by the file manifest.yml in the go, nodejs, python
and ruby buildpacks to require the specification of one or more
"stacks" associated with each binary dependency. We've also required
the specification of an MD5 checksum for each binary, which is
verified before packaging the dependencies.

Changes

• Added support for cflinuxfs2 stack.
• Binary files now permanently hosted on a CF-managed S3 bucket.
• On lucid64, the following changes were made to package support:
  • Removed support for ruby 1.9.2. The binary for this version,
    included in previous ruby-buildpack releases, is not
    functional. There is a
    track of work
    scheduled to recreate binaries for all our stacks; but for this
    release, generating replacement binaries was deprioritized. That
    said,
    ruby 1.9.2 has reached end-of-life, and
    at this moment we do not plan to support 1.9.2 in future
    cflinuxfs2 buildpack releases.
• On cflinuxfs2, only the following interpreter versions are supported:
  • ruby 2.2.0, 2.1.{2,3,4,5}, 2.0.0, and 1.9.3.
  • jruby 1.7.{1-11}.
  • See manifest.yml for full details.
• The buildpack has increased in size with this release, from 825M to 922M.
