* Remove signature verification in backing. `SignedFullStatement` now signals that the signature has already been checked. * Remove unused check_payload function. * Introduced unchecked signed variants. * Fix inclusion to use unchecked variant. * More unchecked variants. * Use unchecked variants in protocols. * Start fixing statement-distribution. * Fixup statement distribution. * Fix inclusion. * Fix warning. * Fix backing properly. * Fix bitfield distribution. * Make crypto store optional for `RuntimeInfo`. * Factor out utility functions. * get_group_rotation_info * WIP: Collator cleanup + check signatures. * Convenience signature checking functions. * Check signature on collator-side. * Fix warnings. * Fix collator side tests. * Get rid of warnings. * Better Signed/UncheckedSigned implementation. Also get rid of Encode/Decode for Signed! *party* * Get rid of dead code. * Move Signed in its own module. * into_checked -> try_into_checked * Fix merge.
