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) Change the error messages "unexpected code byte" to "invalid start byte"
and "invalid data" to "invalid continuation byte";
4) Add an extensive set of tests in test_unicode;
5) Fix test_codeccallbacks because it was failing after this change.
mode raises unicode errors. The encoder only supports "strict" and "replace"
error handlers, the decoder only supports "strict" and "ignore" error handlers.

handler, return a bytes object. If Py_FileSystemDefaultEncoding is not set,
fall back to UTF-8.
This function is only used to decode Python module filenames, but Python
doesn't support surrogates in modules filenames yet. So nobody noticed this
minor bug.

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.

Grow the allocated buffer in PyUnicode_EncodeUTF7 to avoid buffer overrun.
Without this change, test_unicode.UnicodeTest.test_codecs_utf7 crashes in
debug mode. What happens is the unicode string u'\U000abcde' with a length
of 1 encodes to the string '+2m/c3g-' of length 8. Since only 5 bytes is
reserved in the buffer, a buffer overrun occurs.

(In debug build, crash in assert())
This can happen with normal processing, if python starts with utf-8,
then calls sys.setfilesystemencoding('latin-1')

Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
PyUnicode_DecodeUTF8() once, remember the result and output it in a second

of using the replace error handler in PyUnicode_DecodeUTF8().

Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.
Also addresses these, which are intertwined with the short repr
changes:
- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515: 'n' formatting with commas no longer works poorly
with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
for floats.
This is incomplete, but I want to get some version into the next alpha. I am still working on:
Documentation.
More tests.
Implement for floats.
In addition, there's an existing bug with 'n' formatting that carries forward to thousands grouping (issue 5515).
