Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
This is meant to allow std::moving the returned object when needed.
Otherwise std::move(s.get_vector()) will be degraded to copying.

This class implements an add-only vector that ensures that the elements are
unique.
As long as items are only added this class does essentially the same what Java's
LinkedHashSet does.
