* seal: Change prefix "ext_" to "seal_" for contract callable functions The word Ext is a overloaded term in the context of substrate. It usually is a trait which abstracts away access to external resources usually in order to mock them away for the purpose of tests. The contract module has its own `Ext` trait in addition the the substrate `Ext` which makes things even more confusing. In order to differentiate the contract callable functions more clearly from this `Ext` concept we rename them to use the "seal_" prefix instead. This should change no behaviour at all. This is a pure renaming commit. * seal: Rename import module from "env" to "seal0" * seal: Fixup integration test * seal: Add more tests for new import module names

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.
