Since Python 3.3 PyUnicode_AsUnicodeAndSize() is deprecated in favour of PyUnicode_AsWideChar() and PyUnicode_AsWideCharString(). But the latter two are implemented using PyUnicode_AsUnicodeAndSize(). This prevents adding the deprecation compiler warning for PyUnicode_AsUnicodeAndSize(). Other side effect -- PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() cache the wchar_t* representation of the PyUnicode object increasing its memory consumption.

Proposed patch reimplements PyUnicode_AsWideChar(), PyUnicode_AsWideCharString() and PyUnicode_AsUnicodeAndSize() using two common helper functions. PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() no longer cache the wchar_t* representation.
