8b097b4ed7 Close #17828: better handling of codec errors 
- output type errors now redirect users to the type-neutral
  convenience functions in the codecs module
- stateless errors that occur during encoding and decoding
  will now be automatically wrapped in exceptions that give
  the name of the codec involved

ad14ccd047 Issue #19512: add _PyUnicode_CompareWithId() function 
_PyUnicode_CompareWithId() is faster than PyUnicode_CompareWithASCIIString()
when both strings are equal and interned.

Add also _PyId_builtins identifier for "builtins" common string.

fd9e44db37 Issue #16286: optimize PyUnicode_RichCompare() for identical strings (same 
pointer) for any operator, not only Py_EQ and Py_NE.

Code of bytes_richcompare() and PyUnicode_RichCompare() is now closer.

602f7cf0b9 Issue #19424: Optimize PyUnicode_CompareWithASCIIString() 
Use fast memcmp() instead of a loop using the slow PyUnicode_READ() macro.
strlen() is still necessary to check Unicode string containing null bytes.

68b674c9d4 Issue #19437: Fix _PyUnicode_New() (constructor of legacy string), set all 
attributes before checking for error. The destructor expects all attributes to
be set. It is now safe to call Py_DECREF(unicode) in the constructor.

fa3ba4c3bc Issue #18609: Add a fast-path for "iso8859-1" encoding 
On AIX, the locale encoding may be "iso8859-1", which was not a known syntax of
the legacy ISO 8859-1 encoding.

Using a C codec instead of a Python codec is faster but also avoids tricky
issues during Python startup or complex code.

e699e5a218 Issue #18408: Don't check unicode consistency in _PyUnicode_HAS_UTF8_MEMORY() 
and _PyUnicode_HAS_WSTR_MEMORY() macros

These macros are called in unicode_dealloc(), whereas the unicode object can be
"inconsistent" if the creation of the object failed.

For example, when unicode_subtype_new() fails on a memory allocation,
_PyUnicode_CheckConsistency() fails with an assertion error because data is
NULL.

* _Py_char2wchar() now returns a buffer allocated by PyMem_RawMalloc(), instead
  of PyMem_Malloc()

bb4503f61e Partial revert of changeset 9744b2df134c 
PyUnicode_Append() cannot call directly resize_compact(): I forgot that a
string can be ready *and* not compact (a legacy string can also be ready).

8f674ccd64 Close #17694: Add minimum length to _PyUnicodeWriter 
* Add also min_char attribute to _PyUnicodeWriter structure (currently unused)
 * _PyUnicodeWriter_Init() has no more argument (except the writer itself):
   min_length and overallocate must be set explicitly
 * In error handlers, only enable overallocation if the replacement string
   is longer than 1 character
 * CJK decoders don't use overallocation anymore
 * Set min_length, instead of preallocating memory using
   _PyUnicodeWriter_Prepare(), in many decoders
 * _PyUnicode_DecodeUnicodeInternal() checks for integer overflow
