* Put the DB configuration in an enum

* Allow passing a custom database to client-db

* Clean-ups in client-db

* Hopefully fix tests for good this time 😩

* Address review

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

* grandpa: fix handling of catch-up requests

* grandpa: fix tests

* grandpa: add test for catch-up handling when observer disabled

* grandpa: extend doc comment

* grandpa: rename existing catch up test

* 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

* test added

* another dep removed

* Test on variable limb lengths

* Change license

* Rework division

* 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.

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 027d8879 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 027d8879, leaving `core/authority-discovery`
and `srml/authority-discovery` untouched.
