Fix "--disable-mining" build regression
closes#4634
Test by building with:
* `CONFIGURE_FLAGS="--disable-tests --disable-mining --disable-bench" zcutil/build.sh`
* `zcutil/distclean.sh`
* `CONFIGURE_FLAGS="--disable-mining" zcutil/build.sh`
After the second build, run `qa/zcash/full-test-suite.py`. Stop when it gets to the RPC tests, which will hang. The preceding parts of the test suite are all expected to pass.

Pass HistoryNode through Rust FFI as a C array
`std::array<T>` is guaranteed to store `T` contiguously. However, there is
no guarantee that `sizeof(std::array<unsigned char, N>) == N`, which
prevents us from interpreting `std::array<std::array<unsigned char, N>, 32>`
as `&[[u8; N]]` on the Rust side of the FFI.
Instead, we define `HistoryNode` as a struct wrapping a C array, which
(as checked by `static_assert`) contains no padding.
This is equivalent to 82fe37d22b, which
fixed this issue when passing a slice of `HistoryEntry`s from C++ to Rust;
the bug fixed here is writing `HistoryNodes` from Rust into C++ memory.
This prevents the metrics screen from flashing if locks are being held
by long-running processes, specifically cs_main during block validation.
We split up locking on cs_main and cs_vNodes to make obtaining the locks
easier, at the expense of potentially having slightly out-of-sync
statistics (which doesn't really matter, as all we are fetching from the
latter lock is the number of connected peers).
Wallet must come before crypto, otherwise linking fails on some platforms.
Includes a tangentially-related general cleanup rather than making the Makefile
sloppier.
Verify that results correct (match known values), consistent (encrypt->decrypt
matches the original), and compatible with the previous openssl implementation.
Also check that failed encrypts/decrypts fail the exact same way as openssl.
The output should always match openssl's, even for failed operations. Even for
a decrypt with broken padding, the output is always deterministic (and attemtps
to be constant-time).
Post-Heartwood cleanups
The C++ Equihash validator is removed; the Rust validator is now used unconditionally for the entire chain.
Changes made to enable contextually switching between the two validators have been reverted.
Also fixes a segfault that could occur on reindex during consensus-related development.
