* Adds new wrapper traits for wasm executor * Add new crate `substrate-wasm-interface` Thew new crate holds types and traits for the communicating between the wasm runtime and the host. * Rewrite externals with new macro etc * Fix vec initialization * Make executor tests working * Remove unused code + warnings * Introduce `Pointer` and `WordSize` for working with wasm * Fix tests and compilation * Fix compilation * Apply suggestions from code review Co-Authored-By: Sergei Pepyakin <sergei@parity.io> * Review feedback * Remove unused conversions * Make each host function its own struct `HostFunctions` now just returns these function structs. Each function can be executed by using one of the function structs. The inherent host functions are now moved to the "normal" host functions. * Remove byteorder * Add floating point types * Make pointer interface more safe * Add type alias for wasm-interface Result * More review comments
