* Add support for Grandpa warp sync

* Don't pull the warp sync crate if not full-node

* Compress the PoV block before sending it over the network

This pr changes the way we send PoV blocks over the network. We now
compress the PoV block before it is send over the network. This should
reduce the size significant for PoVs which contain the runtime WASM for
example.

* Preallocate 1KB

* Try something..

* Switch to zstd and some renamings

* Make compression/decompression fail in browsers

* Use some sane maximum value

* More doc fixes.

* Minor refactorings in the process of #2177

By having everything peer set related depend directly on the enum the
code becomes more clear and it is also straight forward to add more
peersets/protocols as the compiler will complain if you forget to
implement parts of it.

* Add peer set infos on startup properly

For feature real_overseer.

+ Fixes from review. Thanks @coriolinus and @ordian

!

* More structure in network-bridge

Some changes, which would have helped me in groking the code faster.

Entry points/public types more to the top. Factored out implementation
in their own files, to clear up the top-level view.

* Get rid of local ProtocolName type definition.

Does not add much at this level.

* Fix tests + import cleanup.

* Make spaces tabs.

* Clarify what correct parameters to send_message are

* Be more less vague in docs of send_message.

* Apply suggestions from code review

Extend copyright on new files to 2021 as well.

* subsystems have an unbounded channel to the overseer

* Update node/overseer/src/lib.rs

Co-authored-by: Bernhard Schuster <[email protected]>

* bump Cargo.lock

Co-authored-by: Bernhard Schuster <[email protected]>

* Do not send empty view updates to peers

It happened that we send empty view updates to our peers, because we
only updated our finalized block. This could lead to situations where we
overwhelmed sub systems with too many messages. On Rococo this lead to
constant restarts of our nodes, because some node apparently was
finalizing a lot of blocks.

To prevent this, the pr is doing the following:

1. If a peer sends us an empty view, we report this peer and decrease it
reputation.

2. We ensure that we only send a view update when the `heads` changed
and not only the `finalized_number`.

3. We do not send empty `ActiveLeavesUpdates` from the overseer, as this
makes no sense to send these empty updates. If some subsystem is relying
on the finalized block, it needs to listen for the overseer signal.
