LoadSnapshot previously opened LevelDB directly at <datadir>/txleveldb to
write the snapshot in. Refactored to use the CTxDBBase abstraction:
- WipeChainDataDir() removes the configured backend's chain DB dir
- MakeChainDB("c+") opens fresh via the factory
- High-level methods (WriteBlockIndex, WriteUtxo, WriteHashBestChain,
WriteVersion, WriteDbFormat) replace manual key/value construction
- TxnBegin/Commit cycles every 1000 headers / 50000 UTXOs preserve the
prior batching cadence
The IsRocksDbChainBackend() guard added in 76579e3 is dropped — snapshot
loading now works on either backend.
Two adjacent paths in init.cpp also hardcoded "txleveldb": the snapshot
auto-load guard (Step 6c) and the -reindex datadir wipe. Both updated to
GetChainDataDir() / WipeChainDataDir() so they pick the right directory
for the configured backend.
Helpers added to txdb.h / txdb-factory.cpp:
- GetChainDataDir(): on-disk path of the configured backend's chain DB
- WipeChainDataDir(): rm -rf the same path
Bootstrap archive paths (bootstrap.cpp lines 721+) intentionally still
reference txleveldb specifically — the prebuilt-index distribution
remains LevelDB-format until that pipeline is ported separately.
