Upstream OSS-Fuzz build recipe
(google/oss-fuzz/projects/coturn/build.sh) only copies two fuzzer
binaries -- FuzzStun and FuzzStunClient -- and their seed corpora into
$OUT. The eight additional fuzz targets added later never ran on
oss-fuzz.com, which is why the introspector profile reports "fuzzer no
longer available" for them.
Rather than patching the Google-owned build recipe, fold all fuzzers
into the two binaries OSS-Fuzz actually ships. Each target now begins
with a single-byte selector (Data[0] mod 5) that dispatches to one of
five sub-harnesses:
FuzzStun - integrity (SHA1/multi-SHA), attr_iter, attr_add,
old_stun
FuzzStunClient - stun_client, channel_data, addr_codec, oauth_token,
oauth_roundtrip
No upstream OSS-Fuzz changes are required.
