Support using UCS-4 as the Py_UNICODE type: Add configure option --enable-unicode. Add config.h macros Py_USING_UNICODE, PY_UNICODE_TYPE, Py_UNICODE_SIZE, SIZEOF_WCHAR_T. Define Py_UCS2. Encode and decode large UTF-8 characters into single Py_UNICODE values for wide Unicode types; likewise for UTF-16. Remove test whether sizeof Py_UNICODE is two.
