Miner configuration is unified under [Eth.Miner] (GasCeil/GasPrice/Etherbase/ExtraData), replacing legacy top-level [Eth] miner keys.
Operational impact: existing config files using [Eth].GasPrice/[Eth].Etherbase/[Eth].ExtraData must be migrated before upgrade.
Behavior update: gasprice=0 remains valid; only negative gas prices are sanitized at startup.
Default change: XDCGenesisGasLimit is reduced to 42,000,000 and now feeds miner default GasCeil (including default --miner-gaslimit), so nodes relying on defaults should review capacity expectations.
- Add error returns to Database.Reader() and NodeIterator() methods
- Introduce committed flag to prevent usage of tries after commit
- Update callers to handle new error signatures
- Add MustNodeIterator() helper for backward compatibility

This commit removes two redundant SetGasPrice() calls in the startNode function that were causing multiple issues:
1. Overriding txpool's configured price limit with the miner's gas price setting, mixing two independent configurations:
- cfg.Eth.GasPrice (from --miner-gasprice --gasprice flag)
- cfg.TxPool.PriceLimit (from --txpool-pricelimit flag)
2. Reverting runtime gasPrice changes made via RPC. When users call miner_setGasPrice RPC method to adjust the gasPrice dynamically, the changes would be unexpectedly reverted at the next checkpoint when startNode re-applies cfg.Eth.GasPrice.
The txpool already initializes its gasPrice from config.PriceLimit during construction (core/txpool/txpool.go:333):
```go
func NewTxPool(config Config, chainconfig *params.ChainConfig, chain blockChain) *TxPool {
pool := &TxPool{
gasPrice: new(big.Int).SetUint64(config.PriceLimit),
}
```
When mining is started via RPC (miner_start), the MinerAPI.Start() method handles gasPrice propagation correctly.
This change ensures:
- The txpool respects its own configuration
- Runtime gasPrice adjustments via RPC persist across checkpoints
- No unexpected overriding of user-configured values
This PR introduces a node scheme abstraction. The interface is only implemented by `hashScheme` at the moment, but will be extended by `pathScheme` very soon.
Apart from that, a few changes are also included which is worth mentioning:
- port the changes in the stacktrie, tracking the path prefix of nodes during commit
- use ethdb.Database for constructing trie.Database. This is not necessary right now, but it is required for path-based used to open reverse diff freezer
