They are not doing anything right now. This is in preparation for their
complete removal from the tree.
Note: several changes that affect the derivation inputs (e.g. removal of
references to stub paths in build instructions) were left out. They will
be cleaned up the next iteration and will require special care.
Note: this PR is a result of a mix of ugly regex (not AST) based
automation and some manual labor. For reference, the regex automation
part was hacked in: https://github.com/booxter/nix-clean-apple_sdk

When reworking the percona package naming towards the two release
streams "innovation" and "lts", I did not anticipate the case that two
releases are long-term supported in parallel, and that the latest
Innovation release is end-of-life and replaced by a more recent lts.
Hence, the first-level attribute names now reflect the package
major-minor versions again, augmented by attribute names pointing to
respective lts and innovation releases.
