* seal: Change prefix "ext_" to "seal_" for contract callable functions

The word Ext is a overloaded term in the context of substrate. It usually
is a trait which abstracts away access to external resources usually in order
to mock them away for the purpose of tests. The contract module has its own
`Ext` trait in addition the the substrate `Ext` which makes things even more
confusing.

In order to differentiate the contract callable functions more clearly from
this `Ext` concept we rename them to use the "seal_" prefix instead.

This should change no behaviour at all. This is a pure renaming commit.

* seal: Rename import module from "env" to "seal0"

* seal: Fixup integration test

* seal: Add more tests for new import module names

* Rough skeleton for what I think the RPC should look like

* Create channel for sending justifications

Sends finalized header and justification from Grandpa to the
client. This lays the groundwork for hooking into the RPC module.

* WIP: Add subscribers for justifications to Grandpa

Adds the Sender end of a channel into Grandpa, through which notifications
about block finality events can be sent.

* WIP: Add a struct for managing subscriptions

Slightly different approach from the last commit, but same
basic idea. Still a rough sketch, very much doesn't compile yet.

* Make naming more clear and lock data in Arc

* Rough idea of what RPC would look like

* Remove code from previous approach

* Missed some things

* Update client/rpc-api/src/chain/mod.rs

* Revalidate transactions only on latest best block

We should revalidate transactions only on the latest best block and not
on any arbitrary block. The revalidation before failed when there were
multiple blocks on the height given to the revalidation function, but no
block was imported as best block.
