794d567b17 any_find_slice() doesn't use callbacks anymore 
* Call directly the right find/rfind method: allow inlining functions
 * Remove Py_LOCAL_CALLBACK (added for any_find_slice)

fb9ea8c57e Don't check for the maximum character when copying from unicodeobject.c 
* Create copy_characters() function which doesn't check for the maximum
   character in release mode
 * _PyUnicode_CheckConsistency() is no more static to be able to use it
   in _PyUnicode_FormatAdvanced() (in formatter_unicode.c)
 * _PyUnicode_CheckConsistency() checks the string hash

c3cec7868b Add asciilib: similar to ucs1, ucs2 and ucs4 library, but specialized to ASCII 
ucs1, ucs2 and ucs4 libraries have to scan created substring to find the
maximum character, whereas it is not need to ASCII strings. Because ASCII
strings are common, it is useful to optimize ASCII.

ce5faf673e unicodeobject.c doesn't make output strings ready in debug mode 
Try to only create non ready strings in debug mode to ensure that all functions
(not only in unicodeobject.c, everywhere) make input strings ready.

c80d6d20d5 Speedup str[a🅱️step] for step != 1 
Try to stop the scanner of the maximum character before the end using a limit
depending on the kind (e.g. 256 for PyUnicode_2BYTE_KIND).

ae86485517 Speedup find_maxchar_surrogates() for 32-bit wchar_t 
If we have at least one character in U+10000-U+10FFFF, we know that we must use
PyUnicode_4BYTE_KIND kind.

b9275c104e Speedup str[a:b] and PyUnicode_FromKindAndData 
* str[a:b] doesn't scan the string for the maximum character if the string
   is ascii only
 * PyUnicode_FromKindAndData() stops if we are sure that we cannot use a
   shorter character type. For example, _PyUnicode_FromUCS1() stops if we
   have at least one character in range U+0080-U+00FF

702c734395 Speedup the ASCII decoder 
It is faster for long string and a little bit faster for short strings,
benchmark on Linux 32 bits, Intel Core i5 @ 3.33GHz:

./python -m timeit 'x=b"a"' 'x.decode("ascii")'
./python -m timeit 'x=b"x"*80' 'x.decode("ascii")'
./python -m timeit 'x=b"abc"*4096' 'x.decode("ascii")'
