The refactoring in particular helps enable the "try using inquisition's getblocktemplate, and if that doesn't work fall back to core's getblocktemplate" logic, as described/implemented in https://github.com/bitcoin-inquisition/bitcoin/pull/7 ACKs for top commit: achow101: ACKfb6d51eb25danielabrozzoni: Code review ACKfb6d51eb25Tree-SHA512: d84095c4045ab196685b847e04ce2cdaedf387bc2527430ede918318dc5b70bf3d87b754264016f895f506fac70d4fdea5ef3cd8c3c375fd586afeae01e045e5
