Many error messages would say "see debug.log" or similar, without
indicating where the debug log actually lives. This now prints the
actual path in those cases.
It also changes more general uses of "debug.log" to "debug log", since
the file name may not even be "debug.log" if the user has specified it.
Zcash: Excluding change to `BlockWitnessMerkleRoot` as we don't have
SegWit (deploying non-malleable txs via ZIP 244 instead).

Zcash: Commented out second BENCHMARK argument as we haven't backported
the benchmark refactor that adds it.

The change to use Orchard batch validation now requires the Orchard
verifying key to be available even if there are no items in the batch.
For simplicity, we now load all verifying keys in the Boost tests.
The ZIP 244 changes mean that we're going to need to alter every
callsite to pass through all of the transparent `CTxOut`s being spent.
Given that we need to pass it over to Rust, it makes more sense to just
have `PrecomputedTransactionData` be the vehicle for conveying this data
across.
In addition to the specified consensus rules, we unconditionally enable
ZIP 216 in the following situations:
- Wallet code
- Transaction building
- Nullifiers for wallet notes
- Tests
- Benchmarks
Closeszcash/zcash#5201.
crypto_sign_verify_detached is still used within the consensus rules
until Canopy activation. ed25519-zebra generates signatures that are
valid under both pre- and post-Canopy rules (for our honest usage),
so we can use it to generate transaction signatures now. Then once
Canopy activates, we can remove the remaining usages of crypto_sign.
We don't support making pre-Sapling JoinSplit proofs, and we load the
parameters for post-Sapling JoinSplit proofs at proving time, so there
is no need for a global ZCJoinSplit to be passed through the APIs.
Worst-case block verification benchmarks
The micro-benchmark framework from #3858 is used to measure the time to verify various transaction components. These are leveraged by a script that simulates the verification cost of different compositions of full blocks.
lastCycles was introduced in 35328187463a7078b4206e394c21d5515929c7de which was merged into master yesterday.
Also initialize beginCycles to zero for consistency and completeness.
std::chrono removes portability issues.
Rather than storing doubles, store the untouched time_points. Then
convert to nanoseconds for display. This allows for maximum precision, while
keeping results comparable between differing hardware/operating systems.
Also, display full nanosecond counts rather than sub-second floats.
We were saving a div by caching the inverse as a float, but this
ended up requiring a int -> float -> int conversion, which takes
almost as much time as the difference between float mul and div.
There are lots of other more pressing issues with the bench
framework which probably require simply removing the adaptive
iteration count stuff anyway.
Avoid static analyzer warnings regarding "Function call argument
is a pointer to uninitialized value" in cases where we are
intentionally using such arguments.
This is achieved by using ...
`f(b.begin(), b.end())` (`std::array<char, N>`)
... instead of ...
`f(b, b + N)` (`char b[N]`)
Rationale:
* Reduce false positives by guiding static analyzers regarding our
intentions.
