Throw argument errors during construction instead of passing them in a callback

[reconbot]

Right now options errors when creating a serialport happen in a callback that is called immediately if provided to the constructor or emitted on the factory object. Lets throw these errors immediately.

We won't need the factory after this which things even further.

I suggest we return the constructor, but keep a copy of it on a SerialPort property as to not confuse too many people with this change. (eg, most example code on the net will continue to work) which we can depreciate later. list and parsers will also need to be properties of the constructor function too.
