Add ChainstateManagerOpts, using as ::Options [META] Although it seems like we don't need it for just one option, we're going to introduce another member to this struct in the next commit. In future patchsets for libbitcoinkernel decoupling it from ArgsManager, even more members will be added here. 2022-03-01 16:14:12 -05:00			`// Copyright (c) 2022 The Bitcoin Core developers`

Add ChainstateManager::m_adjusted_time_callback This decouples validation.cpp from netaddress.cpp (transitively, timedata.cpp, and asmap.cpp). This is important for libbitcoinkernel as: - There is no reason for the consensus engine to be coupled with netaddress, timedata, and asmap - Users of libbitcoinkernel can now easily supply their own std::function that provides the adjusted time. See the src/Makefile.am changes for some satisfying removals. 2022-03-01 16:14:12 -05:00			`const std::function<int64_t()> adjusted_time_callback{nullptr};`
