* Re-use the old tip change if there is no new tip change
Also improve the comments.
* Add an assertion message
* Rename task join handles and futures in start method
* Add a dedicated BlockGossipError type
This type helps distinguish between syncer and state errors.
* Test that committed blocks are gossiped to peers
Also do a minor type cleanup on the existing test code,
replacing `Option<Vec<_>>` with `Vec<_>`.
* Formatting
* Remove excess newlines

* Use `MockService` in inbound test
Refactor the `mempool_requsets_for_transactions` test so that it uses a
`MockService` instead of the `mock_peer_set` function.
* Use `MockService` in the basic mempool test
Refactor the `mempool_service_basic` test so that it uses a
`MockService` instead of the `mock_peer_set` helper function.
* Remove the `mock_peer_set` helper function
It is not used anymore, since the usages were replaced with
`MockService`s.

* Create initial `mempool::Crawler` type
The mempool crawler is responsible for periodically asking peers for
transactions to insert into the local mempool. This initial
implementation will periodically ask for transactions, but won't do
anything with them yet.
Also, the crawler is currently configured to be always enabled, but this
should be fixed to avoid crawling while Zebra is still syncing the
chain.
* Add a timeout to peer responses
Prevent the crawler from getting stuck if there's communication with a
peer that takes too long to respond.
* Run the mempool crawler in Zebra
Spawn a task for the crawler when Zebra starts.
* Test if the crawler is sending requests
Create a mock for the `PeerSet` service to intercept requests and verify
that the transaction requests are sent periodically.
* Use `full` Tokio features when testing
Make it simpler to select the features for test builds.

* Link to the issue for crawler activation
Make it easy to navigate from the `TODO` comment to the current project
planning.

Remove the seed command entirely, and make the behavior it provided
(responding to `Request::Peers`) part of the ordinary functioning of the
start command.
The new `Inbound` service should be expanded to handle all request
types.
* Add a TracingConfig and some components

* Restructure, use dependency injection, initialize tracing
* Start a placeholder loop in start command
* Add hyper alpha.1, bump tokio to alpha.4
* Hello world endpoint using async/await from hyper 0.13 alpha
Also cleaned up some linter messages.

* Update to tracing_subscriber 0.1
* fmt
* add rust-toolchain
* Remove hyper::Version import
* wip: start filter_handler impl
* Add .rustfmt.toml
* rustfmt
* Tidy up .rustfmt.toml
* Add filter reloading handling.
* bump toolchain
* Remove generated hello world acceptance tests.
These test the behaviour of the autogenerated binary and work as examples of
how to test the behaviour of abscissa binaries. Since we don't print "Hello
World" any more, they fail, but we don't yet have replacement behaviour to add
tests for, so they're removed for now.
* Clean up config file handling with Option::and_then.
