- Simplify and consolidate code for parsing hex input.
- Replace beast::endian::order with boost::endian::order.
- Simplify CountedObject code.
- Remove pre-C++17 workarounds in favor of C++17 based solutions.
- Improve `base_uint` and simplify its hex-parsing interface by
consolidating the `SexHex` and `SetHexExact` methods into one
API: `parseHex` which forces callers to verify the result of
the operation; as a result some public-facing API endpoints
may now return errors when passed values that were previously
accepted.
- Remove the simple fallback implementations of SHA2 and RIPEMD
introduced to reduce our dependency on OpenSSL. The code is
slow and rarely, if ever, exercised and we rely on OpenSSL
functionality for Boost.ASIO as well.
Escrow replaces the existing SusPay implementation with improved
code that also adds hashlock support to escrow payments, making
RCL ILP enabled.
The new functionality is under the `Escrow` amendment, which
supersedes and replaces the `SusPay` amendment.
This commit also deprecates the `CryptoConditions` amendment
which is replaced by the `CryptoConditionSuite` amendment which,
once enabled, will allow use of cryptoconditions others than
hashlocks.
