* 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.

Instead of requiring execution proofs for Grandpa authorities, this
enables much simpler storage proofs.

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.

* Make substrate-offchain compile for WASM again

* Minor adjustments

* node: add sentry mode flag

* cli: extend docs on validator and sentry modes

* service: add missing field in test Configuration

* node: Display instead of Debug when printing node role

* Introduce new option "always force new era".

* Take appropriate action, even for small offences.

- Deselect the offender in all circumstances
- Ensure that deselection forces a new era
- Ensure that forcing a new era works with the always-forcing.

* Bump runtime

* Initial sotrage migration

* Fix some deps

* Remove footgun around session keys/handlers

- `OpaqueKeys` now has an associated type `KeyTypeIdProviders`. This can
be used in the runtime as input for `SessionHandler` from the session
trait.
- `impl_opaque_keys` now works with modules and extracts the `KeyTypeId`
from the module directly.
- Added some checks to the `session` storage initialization that checks
that the `SessionHandler` and `Keys` use the same number of keys and
that the order is equal.

* Update core/sr-primitives/src/traits.rs
