Hermes bfdb399772 WIP: modernization applied to DNS2 tree 
Brings in uncommitted work from SAMI-PC E:\repos\triangles
cpp20-modernization branch:
- RocksDB default chain DB + auto-migrate from txleveldb
- SQLite default wallet + non-destructive migration from Berkeley
- Boost.Asio removed from RPC (rpc_httpsocket.h)
- Boost removed from all daemon + GUI code
- New: walletdb-base.h, walletdb-batch.h, walletdb-sqlite.{h,cpp},
  walletdb-factory.{h,cpp}, walletmigrate.{h,cpp}
- New tests: chaindb_runtime_tests, chaindb_equivalence_tests,
  snapshotnet_tests
- Docs: BOOST-REMOVAL.md, ROCKSDB-DEFAULT-MIGRATION.md,
  WALLET-SQLITE-MIGRATION.md

Does not yet build — needs CWalletDB->CWalletBatchTyped rebase in
walletdb.cpp/wallet.cpp/db.cpp and merge with origin/master for
v6 source files (checkpointpublisher, tor/, snapshot/, utxosnapshot,
bootstrap.cpp).

Build flags: -DBUILD_QT=OFF -DUSE_I2P_EMBEDDED=OFF
