* Make host functions return TrapReason This avoids the need to manually store any trap reasons to the `Runtime` from the host function. This adds the following benefits: * It properly composes with the upcoming chain extensions * Missing to set a trap value is now a compile error * Add chain extension The chain extension is a way for the contract author to add new host functions for contracts to call. * Add tests for chain extensions * Fix regression in set_rent.wat fixture Not all offsets where properly updated when changing the fixtures for the new salt on instantiate. * Pre-charge a weight amount based off the specified length * Improve fn write docs * Renamed state to phantom * Fix typo

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.
