* parity-version: betalize 2.0
* Multiple improvements to discovery ping handling (#8771)
* discovery: Only add nodes to routing table after receiving pong.
Previously the discovery algorithm would add nodes to the routing table
before confirming that the endpoint is participating in the protocol. This
now tracks in-flight pings and adds to the routing table only after receiving
a response.
* discovery: Refactor packet creation into its own function.
This function is useful inside unit tests.
* discovery: Additional testing for new add_node behavior.
* discovery: Track expiration of pings to non-yet-in-bucket nodes.
Now that we may ping nodes before adding to a k-bucket, the timeout tracking
must be separate from BucketEntry.
* discovery: Verify echo hash on pong packets.
Stores packet hash with in-flight requests and matches with pong response.
* discovery: Track timeouts on FIND_NODE requests.
* discovery: Retry failed pings with exponential backoff.
UDP packets may get dropped, so instead of immediately booting nodes that fail
to respond to a ping, retry 4 times with exponential backoff.
* !fixup Use slice instead of Vec for request_backoff.

* fetch: replace futures-timer with tokio-timer
Currently the coverage build fails because `futures-timer` fails to compile with
`-C link-dead-code`. This issue has been reported to `futures-timer`
(https://github.com/alexcrichton/futures-timer/issues/2) but has remained unsolved
for months. It should be fixed by rustc eventually
(https://github.com/rust-lang/rust/issues/45629).

* Might consume slight more memory than pure conditional compilation
flags
* formatting nits
* Enable libusb for android
* Tested by it compiling succesfully with `cargo build --target=armv7--linux-androideabi`
* The binary is ~66 MB

registered on the IoService.
* devp2p: Use 0-initialized memory buffer instead of unsafe.
* Remove send_queue field from public interface of Discovery.
* Rename Datagramm to Datagram.

* Use assert-matches for more readable tests
* Fix Wording and consistency
* network-devp2p: Test for discovery bucket insertion.
All test values are randomly generated and the assertions are checked manually.
Test fails because distance metric is implemented incorrectly.
* network-devp2p: Fix discovery distance function.
The Kademlia distance function (XOR) was implemented incorrectly as a population count.

Optimizations are possible with more access to the discovery state.
