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.

Currently, this involves a lot of explicit cloning, but we
could migrate the return types of the get_* functions to
be copies rather than references since they are mostly copy
types anyway.
I opted to eliminate the constructor in favor of using
Default::default() plus calling a bunch of setters. This
is similar to the model that a Google Protobuf client uses
and I think it looks fine.
* Drop some unnecessary cloning by comparing references
* Fix compiler errors from callsites in tests.
