* 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 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.

There is no reason to consume the GenesisConfig when using it to
initialize a new storage backend. Instead, build_storage and
assimilate_storage now operator on self references.

* if it doesn't though it is ok, account will be created when the amount put is more than existential deposit.

When requesting an explicit fork sync, try to sync from all known peers,
when no specific peers were provided.

make sure to only request it from the locally known peers that are
either ahead or on a par compared to the block number we are looking
for.
