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

f033510fee Cleanup PyUnicode_Append() 
* Check also that right is a Unicode object
 * call directly resize_compact() instead of unicode_resize() for a more
   explicit error handling, and to avoid testing some properties twice
   (ex: unicode_modifiable())

247109e74d Issue #17615: On Windows (VS2010), Performances of wmemcmp() to compare Unicode 
strings are not convincing. For UCS2 (16-bit wchar_t type), use a dummy loop
instead of wmemcmp(). The dummy loop is as fast, or a little bit faster.

wchar_t is only 16-bit long on Windows. wmemcmp() is still used for 32-bit
wchar_t.

69ed0f4c86 Use PyUnicode_READ() instead of PyUnicode_READ_CHAR() 
"PyUnicode_READ_CHAR() is less efficient than PyUnicode_READ() because it calls
PyUnicode_KIND() and might call it twice." according to its documentation.

cfc4c13b04 Add _PyUnicodeWriter_WriteSubstring() function 
Write a function to enable more optimizations:

 * If the substring is the whole string and overallocation is disabled, just
   keep a reference to the string, don't copy characters
 * Avoid a call to the expensive _PyUnicode_FindMaxChar() function when
   possible
