Significant rubocop fixups.

This merge-request contains almost entirely mechanical changes,
with a few exceptions:

* I changed `do_ipv4` and `do_ipv6` to `ipv4` and `ipv6` respectively.
  * This fixed a warning about normal-casing.
* I changed a test-case to compare against both `Integer` and `Fixnum`
  * Suspect this is a ruby-versionism.

The tests continue to pass, so I believe this is safe to merge,
but of course it is still not 100%:

    lib/custodian/queue.rb:135:21: W: Assignment in condition - you probably meant to use ==.

In short this takes care of _most_ of the warnings, but updates requiring
significant code-change have not been applied.
