Optimize lazy imports

[jdemeyer]

1. make _get_object() a cpdef method again, like it was with Cython 0.18 and before, see Upgrade to Cython 0.19 #14452. This exposes a Python bug (incorrectly claimed to be a Cython bug) which needs to be fixed.

2. use PyObject_RichCompare() as a shortcut in __richcmp__().

3. use print syntax compatible with Python 3.

Nearly trivial, but from my interpretation of the 3rd party packaging doc, we were suppose to have the first patched version be .p0? If we are suppose to be .p1, then you can set a positive review. Otherwise, you can set positive review after the appropriate change.

I really don't think it matters if it's .p0 or .p1. But I'll change it because you ask.
