Repoint ADR references after HQ consolidated 65 records to 23

96 comments across the two repos named records that no longer exist. Each now
points at the consolidated record that holds its reasoning -- ADR 0034 (a test
defends a decision) is 0017, the eight host records are 0005, the four lab
records are 0016.

Worth noting for next time: these are references from outside HQ, so renumbering
there is not free. It cost 38 files here.
