commit 50a405f579c9e00a62f60d2f162ebfeb213aa3f5
Author: Marco Nilsson <denravonska@gmail.com>

    Remove unused variables from CBlockIndex and remove redundant std::string assignments in constructor.

    sizeof(CBlockIndex) drops from 408 to 360 bytes and the overall memory consumption
    drops from peak 453MiB to 417MiB, or by 8%.
