admin: Relicense code under Apache 2.0 (#3989)

This is Update 5, the original PR is ongoing and we will continue to
update as additional people relicense.

Per PR #3905 (#3905), update the
RELICENSING document with the names of people and companies who have
signed on to the relicensing thus far, and update the SPDX license
notices on source files whose extant authorship (per 'git blame')
comprises only authors who have relicensed.
