Add four, basic fuzz tests. This change adds fuzzing tests for: ∙ Certificate parsing ∙ Private key parsing ∙ ClientHello parsing ∙ Server first flow (ServerHello, Certificate, etc) parsing.

Build the fuzzers with -Wno-missing-prototypes. There's not much point in enforcing this on these files, and clang complains about LLVMFuzzerTestOneInput.

Switch to Clang 6.0's fuzzer support. With Clang 6.0, libFuzzer is now included and there's a new -fsanitize=fuzzer command to enable the needed compiler actions.

Support symbol prefixes - In base.h, if BORINGSSL_PREFIX is defined, include boringssl_prefix_symbols.h - In all .S files, if BORINGSSL_PREFIX is defined, include boringssl_prefix_symbols_asm.h - In base.h, BSSL_NAMESPACE_BEGIN and BSSL_NAMESPACE_END are defined with appropriate values depending on whether BORINGSSL_PREFIX is defined; these macros are used in place of 'namespace bssl {' and '}' - Add util/make_prefix_headers.go, which takes a list of symbols and auto-generates the header files mentioned above - In CMakeLists.txt, if BORINGSSL_PREFIX and BORINGSSL_PREFIX_SYMBOLS are defined, run util/make_prefix_headers.go to generate header files - In various CMakeLists.txt files, add "global_target" that all targets depend on to give us a place to hook logic that must run before all other targets (in particular, the header file generation logic) - Document this in BUILDING.md, including the fact that it is the caller's responsibility to provide the symbol list and keep it up to date - Note that this scheme has not been tested on Windows, and likely does not work on it; Windows support will need to be added in a future commit Change-Id: If66a7157f46b5b66230ef91e15826b910cf979a2 Reviewed-on: https://boringssl-review.googlesource.com/31364 Commit-Queue: David Benjamin <davidben@google.com> CQ-Verified: CQ bot account: commit-bot@chromium.org <commit-bot@chromium.org> Reviewed-by: David Benjamin <davidben@google.com>

Fix corner case in cpuinfo parser. I realized looking at the sigalgs parser that I messed up the space-splitting logic slightly. If the CPU features are "foo bar baz", it would not parse "baz". This doesn't particular matter (the last one is "crc32"), but better to parse it correctly. Fix this and add a unit test. While I'm here, may as well add a fuzzer too.
