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.

of range.

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.

platforms other than Windows. Patch written by Campbell Barton.

8486f9b134 Fix "warning: comparison between signed and unsigned integer expressions" 
-Wsign-compare warnings in unicodeobject.c.  These were all a result
of sizeof() being unsigned and being compared to a Py_ssize_t.
Not actual problems.
