Governance

• Pruned nodes can now run governance. Proposal collateral is now looked up in a new governance collateral index instead of -txindex. The index stores only the transactions that could be a proposal's collateral, works with -prune, and always runs; there is no option for it. Pruned nodes, and nodes started with -txindex=0, now sync proposals and votes, check superblock payments in full, and can create and submit proposals.

• Every node builds the index once, on the first start after upgrading. It reads every block for that, and the node's governance sync waits until it has finished.

• A node that pruned blocks before it had this index can't build it, because the index has to start from the genesis block. It now starts with governance turned off and a warning instead of failing; restarting it once with -reindex downloads the blockchain again and enables governance, and the node stays pruned. This replaces the warning such nodes showed before, that governance is disabled because the node is pruned.

• Dash-Qt used to save disablegovernance=1 in settings.json when pruning was turned on in the options. That setting stays until it is removed, so governance stays off on those nodes.

• gobject prepare and gobject submit now fail straight away on a node that can't check or relay proposals. Before, gobject prepare burned the proposal fee and only gobject submit failed afterwards, with the misleading error Invalid proposal collateral. Collateral errors now also say what is wrong with the collateral instead of only Invalid proposal collateral.

• Pruned nodes now check superblock payments against the governance triggers they know, like full nodes do, instead of only checking that a superblock stays within the budget.

• getindexinfo reports the new index as govcollateralindex.

• Starting with -prune and -disablegovernance=0 is no longer an error. Governance validation no longer needs -txindex.
