Alec Cooper ba01182ec4 Fixing Python primitive conversions 
Don't mistakenly treat PyLong objects as PyInt objects in Python3.
  This resolves issues of large integers being incorrectly treated as -1 while also having
  an OverflowError set internally for converting PyLong->long and PyLong->double
Conversions from PyLong to long, unsigned long, long long, and unsigned long long now
raise OverflowError rather than TypeError when given an out of range value.
Removing unnecessary check for PyLong_AsLong when converting PyLong->unsigned long since the
call to PyLong_AsUnsignedLong will have covered this case.
