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 a special partitioner that will be used by
CDC Log. It works only with partition key that is blob
composed of two ints. The first int is a token this
partitioner will map the key to. The second int is there
to make it possible to create multiple keys that are different
from each other but map to the same token.
