Instead of having a pair of bespoke build definitions use the standard FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION toggle. We actually originated the idea of a fuzzing-specific build toggle, and then libFuzzer standardized a toggle when we talked to them about what we were doing. The problem is our fuzzer mode toggle substantially changed the TLS stack behavior, such that downstream code would likely go haywire. So we couldn't easily fold into the standard one, and all of BoringSSL's downstream fuzzer builds were messy. Instead, make a few changes: 1. Switch BORINGSSL_UNSAFE_DETERMINISTIC_MODE to FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION. That flag is not expected to cause downstream issues as it just makes the PRNG deterministic. 2. Replace BORINGSSL_UNSAFE_FUZZER_MODE with a runtime toggle that is only available when building with FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION. 3. Instead of the no_fuzzer_mode fuzzers being special corpora for the client and server fuzzers, they're now just separate fuzzerrs and follow the usual naming conventions between fuzzers and their corpora. Update-Note: Downstream fuzzer builds can now be simplified. If the fuzzing infrastructure already builds with FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION, the separate boringssl_fuzz (or whatever) target can be removed.
