* Implement public helpers for querying header info * Update `best_header` when importing headers * Add BestHeader to GenesisConfig * Define extra types for Millau primitives * Start implementing runtime APIs in Millau runtime * Add helper for getting headers which require a justification * Add runtime API for getting headers requiring a justification * Reword `expect()` proof for valid authority sets * Fix typo * Clean up Hasher comment * Add the Call Dispatch Pallet back to the Millau runtime * Use types from Rialto in bridge pallet config * Use the Rialto runtime APIS in the Millau runtime * Include Millau bridge instance in Rialto runtime * Add missing doc comment * Use one storage function for setting and clearing `RequiresJustification` * Remove TODO comments
