Based on discussion in PR 660.

_PyUnicodeWriter_Prepare() is used incorrectly in unicode_decode_call_errorhandler_writer(), _PyUnicode_DecodeUnicodeEscape() and PyUnicode_DecodeRawUnicodeEscape() in Objects/unicodeobject.c. The second argument is the number of characters that should be reserved after the current position. But in these places the total minimal size is passed to _PyUnicodeWriter_Prepare(). This can lead to allocating more memory than necessary.
