- Fix unlikely edge case in setCurrentThreadName
setCurrentThreadName accepts a std::string_view parameter, which is
not guaranteed to include a null terminator, which it then forwards
to OS-specific APIs that expect null-terminated C strings.
- Fix several compilation warnings
- Fix header includes
- Fix unnecessarily verbose logging
- Simplify code using inline lambdas instead of std::bind
- Modernize the Beast "lexical cast" framework
- Use boost::asio types instead of legacy Beast type wrappers
- Clean up LogicError, custom exception throwing and termination handling
- Clean up and modernize PublicKey, SecretKey and Seed
Simplify construction, buffer iteration and comparisons by leveraging
modern C++ features.
- Clean up and modernize RFC1751 code
Turn static-member-only class into namespace, thin out the public API
and make code noexcept and constexpr. Verify internal data at compile
time.
- Clean up CSPRNG engine
- Clean up rngfill function, eliminating GCC false-positive warning.
- Improve Slice comparison using C++ operator<=> and operator synthesis.
