CalcGasLimit computes the gas limit of the next block after parent.

calculate the gas for migration; no checks done here similar to other functions the checks are handled by staking_verifier.go, ex, if you try to delegate to an address who is not a validator - you will be charged all gas passed in two steps - 22k initially when gas is calculated - remainder when the tx inevitably is a no-op i have followed the same logic here, this only produces an error if can't read from db.
