* pallet-mmr: extend batch proof verification test covers all possible 2-leaf combinations now, including current verification failures that batch proof item count limit is too low sometimes. * raise upper bound on proof item number as described in https://github.com/paritytech/substrate/issues/11753#issuecomment-1179838174 * test for powerset of leaves * refactor batch proof verification test * test all batch proofs for mmr sizes up to n=13 * limit mmr size to reduce batch proof test duration * use saturating integer addition for proof check * extract common chain building in batch proof tests note: right now, since not killing old chain, it keeps growing by 7 blocks for every leaf selection (added after proof generation), hence heavier to compute. * only add blocks after a proof generation once * increase batch proof testing range * register offchain extensions only once * fmt & remove unused util

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
