This makes it easier to build eggs and wheels of 0.19.x releases; the
master branch already uses setuptools.

    * Fix self / other typecode compatibility check and add test

    * In CPython, PyErr_BadArgument() C-API function always raises an
      exception and returns zero

    * It is needed to add the `except -2` clause, so that the exception
      raised by PyErr_BadArgument() is not ignored

    * Additionaly, the `return -1` statement in array.extend() will have
      no effect, and hence is misleading, so it needs to be removed

remove another reference to the old distutils build (in quickstart!) and clarify the description of the Sage notebook a bit
