* Improve complexity of CompactAssignments::unique_targets Original implementation was O(n**2). Current impl is O(n log n). Avoided the original proposed mitigation because it does not retain the de-duplicating property present in the original implementation. This implementation does a little more work, but retains that property. * Explicitly choose sp_std Vec and BTreeSet Ensures that the macro still works if someone uses it in a context in which sp_std is not imported or is renamed. * explicitly use sp_std vectors throughout compact macro

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.
