MSC2836 threading: part 2 (#1596)
* Update GMSL * Add MSC2836EventRelationships to fedsender * Call MSC2836EventRelationships in reqCtx * auth remote servers * Extract room ID and servers from previous events; refactor a bit * initial cut of federated threading * Use the right client/fed struct in the response * Add QueryAuthChain for use with MSC2836 * Add auth chain to federated response * Fix pointers * under CI: more logging and enable mscs, nil fix * Handle direction: up * Actually send message events to the roomserver.. * Add children and children_hash to unsigned, with tests * Add logic for exploring threads and tracking children; missing storage functions * Implement storage functions for children * Add fetchUnknownEvent * Do federated hits for include_children if we have unexplored children * Use /ev_rel rather than /event as the former includes child metadata * Remove cross-room threading impl * Enable MSC2836 in the p2p demo * Namespace mscs db * Enable msc2836 for ygg Co-authored-by: Neil Alexander <neilalexander@users.noreply.github.com>
