Firstly, `Step.duration_remaining` casts it to u32, unnecesarily
limiting it to 2^32. While theoretically this is "good enough" (at 3
seconds steps it provides room for a little over 400 years), it is
still a lossy way to calculate the remaining time until the next step.
Secondly, step duration might be zero, triggering division by zero
in `Step.calibrate`
Solution: rework the code around the fact that duration is
typically in single digits and never grows, hence, it can be represented
by a much narrower range (u16) and this highlights the fact that
multiplying u64 by u16 will only result in an overflow in even further
future, at which point we should panic informatively (if anybody's
still around)
Similarly, panic when it is detected that incrementing the step
counter wrapped around on the overflow of usize.
As for the division by zero, prevent it by making zero an invalid
value for step duration. This will make AuRa log the constraint
mismatch and panic (after all, what purpose would zero step duration
serve? it makes no sense within the definition of the protocol,
as finality can only be achieved as per the specification
if messages are received within the step duration, which would violate
the speed of light and other physical laws in this case).

* Copy modal from keepkey branch and generalize
The keepkey PinMatrix modal needs to be the same for Trezor, but we
should probably try to keep it general since it can be used for both.
* Add trezor communication code
This is a result of much trial-and-error and a couple of dead-ends in
how to communicate and wire everything up.
Code here is still a bit WIP with lots of debug prints and stuff.
The test works though, it is possible to sign a transaction.
* Extend the basic lib to allow Trezor
This is kind of ugly and needs some cleanup and generalization. I’ve
just copy-pasted some things to bring in the trezor wallets. I’ve also
had to add a lock to the USB API so that only one thing talks to the
USB at once.
* Add RPC plumbing needed
We need to be able to get “locked” devices from the frontend to figure
out if we’re going to display the PinMatrix or not. Then we need to be
able to send a pin to a device.
* Add logic to query backend for Trezor and display PinMatrix
There’s a bug somewhere here because signing a transaction fails if you
take too long to press the confirm button on the device.
* Change back to paritytech branch
As my fork has been merged in.
* Converting spaces to tabs, as it should be
* Incorporate correct handling of EIP-155
Turns out the Trezor was adjusting the v part of the signature, and
we’re already doing that so it was done twice.
* Some circular logic here that was incorrect
BE-encoded U256 is almost the same as RLP encoded without the
size-byte, except for <u8 sized values. What’s really done is
BE-encoded U256 and then left-trimmed to the smallest size. Kind of
obvious in hindsight.
* Resolve issue where not clicking fast enough fails
The device will not repeat a ButtonRequest when you read from it, so
you need to have a blocking `read` for whatever amount of time that you
want to give the user to click. You could also have a shorter timeout
but keep retrying for some amount of time, but it would amount to the
same thing.
* Scan after pin entry to make accepting it faster

* Move the PinMatrix from Accounts to Application
* Removing unused dependencies

This test is useless without a connected Trezor, not sure how to make
it useful without one.

# rpc/src/v1/helpers/dispatch.rs
* Ignore test that can't be run without trezor device

* s/network_id/chain_id
* Propagating an error from the HID Api

* Make message type into an actual type
This makes the message type that the RPC message accepts into an actual
type as opposed to just a string, based on feedback. Although I’m not
100% sure this has actually improved the situation.
Overall I think the hardware wallet interface needs some refactoring
love.

It’s split into two more generic endpoints that should be suitable for
any hardware wallets with the same behavior to sit behind.

This is a huge change, which includes some changes to replace code that
originally cloned to reuse allocations instead. The updated
`elastic-array` crate renames its consuming `Vec`-conversion method to
`into_vec`, which means that I can do a simple
`sed -i 's/to_vec/into_vec/'` and then fix the compilation errors.
This commit is probably a minor performance win and definitely a
significant readability win.

* Ethereum Classic Monetary Policy
Create a new parameter `ecip1017EraRounds`. When the block number
passes one era rounds, the reward is reduced by 20%.
See https://github.com/ethereumproject/ECIPs/blob/master/ECIPs/ECIP-1017.md
* Update rewards for uncle miners for ECIP1017
In the monetary policy, the rewards are changed from "up to 7/8 of the
reward" to "1/32 of the reward".
* Fix an off-by-one error in ECIP1017 era calculation
According to
https://github.com/ethereumproject/ECIPs/blob/master/ECIPs/ECIP-1017.md,
when in block number 5,000,000, it should still be in Era 1 (which in
our code `era == 0`). So we need to check whether the `rem` equals to
zero and act accordingly when calculating the era.
