* executor: Use non wasmi-specific execution in tests.
* executor: Move all runtime execution tests into tests file.
* executor: Use test_case macro to easily execute tests with different
Wasm execution methods.
* executor: Convert errors to strings with Display, not Debug.
* node-executor: Rewrite benchmarks with criterion.
They were not passing compilation before and criterion seems to be more
widely used in Substrate.
* executor: Begin implementation of Wasm runtime.
The implementation demonstrates the outline of the execution, but does
not link against the external host functions.
* executor: Define and implement basic FunctionExecutor.
The SandboxCapabilities::invoke is still left unimplemented.
* executor: Implement host function trampoline generation.
* executor: Instantiate and link runtime module to env module.
* executor: Provide input data during wasmtime execution.
* executor: Implement SandboxCapabilites::invoke for wasmtime executor.
* executor: Integrate and test wasmtime execution method.
* executor: Improve FunctionExecution error messages.
* Scope the unsafe blocks to be smaller.
* Rename TrampolineState to EnvState.
* Let EnvState own its own compiler instead of unsafe lifetime cast.
* Refactor out some common wasmi/wasmtime logic.
* Typos and cosmetic changes.
* More trampoline comments.
* Cargo.lock update.
* cli: CLI option for running Substrate with compiled Wasm execution.
* executor: Switch dependency from fork to official wasmtime repo.
* Quiet down cranelift logs.
* Explicitly catch panics during host calls.
We do this to ensure that panics do not cross language boundaries.
* Additional checks and clarifications in make_trampoline.
* Fixes after merge from master and panic safety for wasmtime
instantiation.
As with the native runtime, we now catch all native panics when we
execute the wasm runtime. The panics inside the wasm runtime were
already catched before by the wasm executor automatically, but any panic
in the host functions could bring down the node. The recent switch to
execute the native counterpart of the host function in `sr-io`, makes
this change required. The native `sr-io` functions just `panic` when
something is not provided or any other error occured.
* 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

* 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
