Issue #13706 : Fix format(int, "n") for locale with non-ASCII thousands separator
...
* Decode thousands separator and decimal point using PyUnicode_DecodeLocale()
(from the locale encoding), instead of decoding them implicitly from latin1
* Remove _PyUnicode_InsertThousandsGroupingLocale(), it was not used
* Change _PyUnicode_InsertThousandsGrouping() API to return the maximum
character if unicode is NULL
* Replace MIN/MAX macros by Py_MIN/Py_MAX
* stringlib/undef.h undefines STRINGLIB_IS_UNICODE
* stringlib/localeutil.h only supports Unicode

Issue #13417 : speed up utf-8 decoding by around 2x for the non-fully-ASCII case.
...
This almost catches up with pre-PEP 393 performance, when decoding needed
only one pass.

Replace PyUnicodeObject type by PyObject

Replace PyUnicodeObject* by PyObject* where it was irrevelant
...
A Unicode string can now be a PyASCIIObject, PyCompactUnicodeObject or
PyUnicodeObject. Aliasing a PyASCIIObject* or PyCompactUnicodeObject* to
PyUnicodeObject* is wrong

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.
