Add AFL in zcutil (with all-in-one script)
Supersedes #4156 and #4167.
Fuzzing targets and input sets are defined by the contents of directories in `./src/fuzzing/`. Inside the directory, there's a `fuzz.cpp` and `fuzz.h` with a `main()` function that will replace `zcashd`'s actual `main()` as well as an `input` subdirectory containing the inputs, one per file. To just run a fuzzer, you can, for example...
```
make clean # if you've previously build zcashd without AFL instrumentation
./zcutil/afl/afl-getbuildrun.sh DecodeHexTx
```
Alternatively you can...
```
./zcutil/afl/afl-get.sh /tmp/afl # (or wherever you want to build AFL)
./zcutil/afl/afl-build.sh /tmp/afl DecodeHexTx -j$(nproc)
./zcutil/afl/afl-run.sh /tmp/afl DecodeHexTx
```
Run `make clean` whenever you switch between a normal build and an AFL-instrumented build.
Use CommitTransaction
This enables `-walletbroadcast` to correctly control transactions created with `z_*` APIs. It also addresses some TODOs in the code and consolidates some repeated logic.
Closes#4077 (because `CommitTransaction` calls `KeepKey` on the transparent change address).
add SpentIndex changes needed for bitcore block explorer
Addresses #3708, follow-on to #3837, note there are no tests yet (will come later with RPC interfaces).
depends: Support additional cross-compilation targets in Rust
This will make it easier for third parties to cross-compile `zcashd` for other platforms. The third commit in this PR shows how to add a new target to the Rust dependency builder.
The default Rust target during cross-compilation is the canonical host, which is derived from `HOST` using `depends/config.sub`. If the canonical host differs from the required Rust target, add the necessary mapping in addition to the target itself.
Also includes fixes for cross-compiling aarch64 targets.
The code was already compiled as part of the wallet, but the tests were
not, meaning that the tests would fail to compile when the wallet was
disabled.
By using the flags defined through ./configure instead, libzcash will react to
configuration and build system changes (such as PIC_FLAGS being empty for
Windows builds).
Wallet must come before crypto, otherwise linking fails on some platforms.
Includes a tangentially-related general cleanup rather than making the Makefile
sloppier.
Split out methods to every module, apart from 'help' and 'stop' which
are implemented in rpcserver.cpp itself.
- This makes it easier to add or remove RPC commands - no longer everything that includes
rpcserver.h has to be rebuilt when there's a change there.
- Cleans up `rpc/server.h` by getting rid of the huge cluttered list of function definitions.
- Removes most of the bitcoin-specific code from rpcserver.cpp and .h.
Continues #7307 for the non-wallet.
