Turn ivars into private attr_readers

This makes them more changeable and robust. Ruby will raise
NoMethodError on typos while it'll silently create a new ivar without
us noticing. Also, in my experience, a reader method gives more room to
future refactorings and eases testing because methods are easier to
stub.
