Fix overflow with parameters > LONG_MAX with Python 3.

Browse source 
The typemap incorrectly called PyInt_AsLong() if PyInt_Check() passed, but
this check is the same as PyLong_Check() for Python 3 and so the correct
PyLong_AsUnsignedLong() function was never called. As a consequence, passing
any value greater than LONG_MAX (e.g. 0x87654321 on 32 bit architectures) to a
function taking unsigned int, unsigned long or size_t parameter failed with an
overflow error being generated.

Fix this by simply disabling the part of the code dealing with PyInts for
Python 3 as there is no distinction between PyInt and PyLong there any more.

[Python] Fix overflow when passing values greater than LONG_MAX from Python 3 for parameters with unsigned long C type.

Fix director typemap searching so that a typemap specified with a name will be correctly matched. Previously
the name was ignored during the typemap search. Applies to the following list of typemaps:
