* upgrade primitives to allow changing validation function * set up storage schema for old parachains code * fix compilation errors * fix test compilation * add some tests for past code meta * most of the runtime logic for code upgrades * implement old-code pruning * add a couple tests * clean up remaining TODOs * add a whole bunch of tests for runtime functionality * remove unused function * fix runtime compilation * extract some primitives to parachain crate * add validation-code upgrades to validation params and result * extend validation params with code upgrade fields * provide maximums to validation params * port test-parachains * add a code-upgrader test-parachain and tests * fix collator tests * move test-parachains to own folder to work around compilation errors * fix test compilation * update the Cargo.lock * fix parachains tests * remove dbg! invocation * use new pool in code-upgrader * bump lockfile * link TODO to issue
