[issue7615] unicode_escape codec does not escape quotes

[Richard Hansen]

Richard Hansen <rhansen at bbn.com> added the comment:

Attaching a patch for an issue discovered while looking at the code:
  * The UTF-16 decode logic in the Unicode escape encoders no longer reads past the end of the provided Py_UNICODE buffer if the last character's value is between 0xD800 and 0xDC00.

This patch is meant to be applied after unicode_escape_1_minimal.patch.
