service attacks due to hash collisions within the dict and set types. Patch

Revert r83395, it introduces test failures and is not necessary anyway since we now have to nul-terminate the string anyway.

#8821: do not rely on Unicode strings being terminated with a \u0000, rather explicitly check range before looking for a second surrogate character.

Update PyUnicode_DecodeUTF8 from RFC 2279 to RFC 3629.
1) #8271: when a byte sequence is invalid, only the start byte and all the
valid continuation bytes are now replaced by U+FFFD, instead of replacing
the number of bytes specified by the start byte.
See http://www.unicode.org/versions/Unicode5.2.0/ch03.pdf (pages 94-95);
2) 5- and 6-bytes-long UTF-8 sequences are now considered invalid (no changes
in behavior);
3) Add code and tests to reject surrogates (U+D800-U+DFFF) as defined in
RFC 3629, but leave it commented out since it's not backward compatible;
4) Change the error messages "unexpected code byte" to "invalid start byte"
and "invalid data" to "invalid continuation byte";
5) Add an extensive set of tests in test_unicode;
6) Fix test_codeccallbacks because it was failing after this change.

Issue #1583863: An unicode subclass can now override the __str__ method

Fix the NEWS about my last commit: an unicode subclass can now override the
__unicode__ method (and not the __str__ method).
Simplify also the testcase.

#7649: "u'%c' % char" now behaves like "u'%s' % char" and raises a UnicodeDecodeError if 'char' is a byte string that can't be decoded using the default encoding.

any errors that might occur during coercion of the left operand and
turning them into a TypeError with a message text that was confusing in
the given context. This patch lets any errors through, as was already
done during coercion of the right hand side.
