* Catch native panics when executing the wasm runtime

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.

* 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.

We do this to ensure that panics do not cross language boundaries.

* Fixes after merge from master and panic safety for wasmtime
instantiation.

- 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

* 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

* Fix rest of the errors

The authority discovery module enables authorities to be discoverable
and discover other authorities to improve interconnection among them. In
order to achieve this the module needs to know when the authority set
changes, thus when a session changes.

One has to register a module as a *session handler* in order for it to
be notified of changing sessions. The order and number of these *session
handlers* **MUST** correspond to the order and number of the *session
keys*.

Commit 7fc21cea added the authority discovery to the `SessionHandlers`.
Given that the authority discovery module piggybacks on the Babe session
keys the commit violated the above constraint.

This commit reverts most of 7fc21cea, leaving `core/authority-discovery`
and `srml/authority-discovery` untouched.
