all: avoid awkward wording from CL 236857

CL 236857 removed all uses of whitelist/blacklist, which is great.
But it substituted awkward phrasing using allowlist/blocklist,
especially as verbs or participles. This CL uses more standard English,
like "allow the function" or "blocked functions" instead of
"allowlist the function" or "blocklisted functions".
