eb36fdaad8 Fix _PyUnicodeWriter_PrepareKind() 
Initialize kind to 0 (PyUnicode_WCHAR_KIND) to ensure that
_PyUnicodeWriter_PrepareKind() handles correctly read-only buffer: copy the
buffer.

29e68edbf4 Issue #24848: Fixed bugs in UTF-7 decoding of misformed data: 
1. Non-ASCII bytes were accepted after shift sequence.
2. A low surrogate could be emitted in case of error in high surrogate.
3. In some circumstances the '\xfd' character was produced instead of the
replacement character '\ufffd' (due to a bug in _PyUnicodeWriter).

0030cd52da Issue #25227: Cleanup unicode_encode_ucs1() error handler 
* Change limit type from unsigned int to Py_UCS4, to use the same type than the
  "ch" variable (an Unicode character).
* Reuse ch variable for _Py_ERROR_XMLCHARREFREPLACE
* Add some newlines for readability

f96418de05 Issue #24870: Optimize the ASCII decoder for error handlers: surrogateescape, 
ignore and replace. Initial patch written by Naoki Inada.

The decoder is now up to 60 times as fast for these error handlers.

Add also unit tests for the ASCII decoder.

ac2ef65c32 Make the unicode equality test an external function rather than in-lining it. 
The real benefit of the unicode specialized function comes from
bypassing the overhead of PyObject_RichCompareBool() and not
from being in-lined (especially since there was almost no shared
data between the caller and callee).  Also, the in-lining was
having a negative effect on code generation for the callee.

1912b39def _PyUnicodeWriter_WriteStr() now checks that the input string is consistent 
in debug mode to detect bugs earlier.

_PyUnicodeWriter_Finish() doesn't check if the read only string is consistent,
whereas it does check consistency for strings built by itself.
