admin: Relicense code under Apache 2.0

This is Update 7, the original PR is ongoing and we will continue to
update as additional people relicense.

Per PR AcademySoftwareFoundation#3905 (AcademySoftwareFoundation#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.

To the best of our estimation, we now have 99.85% of lines of code
relicensed, and 93.2% of all source files now consist of ONLY
Apache-2.0 licensed code with no traces of BSD remaining.
