overhaul tests, and many small tweaks.  Most of this is internal to
the project, but there are a few changes to note for everyone:
* Now requires Node 6 or above

messages and not leaving uncaught errors

Everything else done here should be internal facing.  Those changes
include:

* Remove a lot of duplication in tests and many small fixups in tests
* Start using Mocha 4

* Remove the ignoring of errors on close of tests, and tear down tests in general better
* Stop using "new Buffer", that is deprecated, and use Buffer.from() instead
