Honggfuzz NetDriver fd0be92cff6a4b5e343e6ddae7481868354b9869 doc: Add instructions on how to fuzz the P2P layer using Honggfuzz NetDriver (practicalswift) Pull request description: Add instructions on how to fuzz the P2P layer using [Honggfuzz NetDriver](http://blog.swiecki.net/2018/01/fuzzing-tcp-servers.html). Honggfuzz NetDriver allows for very easy fuzzing of TCP servers such as Bitcoin Core without having to write any custom fuzzing harness. The `bitcoind` server process is largely fuzzed without modification. This makes the fuzzing highly realistic: a bug reachable by the fuzzer is likely also remotely triggerable by an untrusted peer.

2020-07-05doc: afl fuzzing comment about afl-gcc and afl-g++nsa
This commit includes a short comment in doc/fuzzing.md that gives guidance on compiling Bitcoin Core with AFL instrumentation using afl-gcc and afl-g++.
2020-06-05build: turn on --enable-c++17 by --enable-fuzzVasil Dimov
Fuzzing code uses C++17 specific code (e.g. std::optional), so it is not possible to compile with --enable-fuzz and without --enable-c++17. Thus, turn on --enable-c++17 whenever --enable-fuzz is used.

2017-05-19[test] Speed up fuzzing by ~200x when using afl-fuzzpracticalswift
Enable the `afl-clang-fast++` features deferred forkserver (`__AFL_INIT`) and persistent mode (`__AFL_LOOP(1000)`). Before this patch: ``` $ afl-fuzz -i input -o output -m512 -- src/test/test_bitcoin_fuzzy [*] Validating target binary... [!] WARNING: The target binary is pretty slow! See /usr/local/share/doc/afl/perf_tips.txt. [+] Here are some useful stats: Test case count : 1 favored, 0 variable, 1 total Bitmap range : 1072 to 1072 bits (average: 1072.00 bits) Exec timing : 20.4k to 20.4k us (average: 20.4k us) … exec speed : 57.58/sec (slow!) exec speed : 48.35/sec (slow!) exec speed : 53.78/sec (slow!) ``` After this patch: ``` $ afl-fuzz -i input -o output -m512 -- src/test/test_bitcoin_fuzzy [*] Validating target binary... [+] Persistent mode binary detected. [+] Deferred forkserver binary detected.
