Running through some of my tests with the `-3` flag in python2.7 I encountered some errors within py.test itself. This fixes those errors so we can use py.test in order to identify problems with Python 3.
The assertion reinterpretation is an old backwards compatibility
mode which was no longer being maintained on feature-parity with
the assertion rewriting mode. It was also responsible for some
dubious patching of builtins and test with side-effects would
suddenly start passing. Since re-writing has been the default for
a long time and plugins are now also re-written it is time to
retire reinterpretation.
While this leads to slightly more complicated user code for the common
case (checking if the exception is of a given type) it's easier to
implement and more flexible.
When __tracebackhide__ gets set to an exception type or list/tuple of
exception types, only those exceptions get filtered, while the full
traceback is shown if another exception (e.g. a bug in a assertion
helper) happens.
