1b487b467b Issue #14624, #14687: Optimize unicode_widen()

3a7f7977f1 Remove buggy assertion in PyUnicode_Substring() 
Use also directly unicode_empty, instead of PyUnicode_New(0,0).

684d5fd420 Fix PyUnicode_Substring() for start >= length and start > end 
Remove the fast-path for 1-character string: unicode_fromascii() and
_PyUnicode_FromUCS*() now have their own fast-path for 1-character strings.

bff7c96834 Issue #14687: Optimize str%tuple for the "%(name)s" syntax

e6abb488c9 unicodeobject.c: Add MAX_MAXCHAR() macro to (micro-)optimize the computation 
of the second argument of PyUnicode_New().

 * Create also align_maxchar() function
 * Optimize fix_decimal_and_space_to_ascii(): don't compute the maximum
   character when ch <= 127 (it is ASCII)

Victor Stinner
b5c3ea3af3 Issue #14687: Optimize str%args 
* formatfloat() uses unicode_fromascii() instead of PyUnicode_DecodeASCII()
   to not have to check characters, we know that it is really ASCII
 * Use PyUnicode_FromOrdinal() instead of _PyUnicode_FromUCS4() to format
   a character: if avoids a call to ucs4lib_find_max_char() to compute
   the maximum character (whereas we already know it, it is just the character
   itself)

d0880d57b0 Simplify and optimize formatlong() 
* Remove _PyBytes_FormatLong(): inline it into formatlong()
 * the input type is always a long, so remove the code for bool
 * don't duplicate the string if the length does not change
 * Use PyUnicode_DATA() instead of _PyUnicode_AsString()

41a863cb81 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

09a7c72cad Merge from 3.1: Issue #13703: add a way to randomize the hash values of basic types (str, bytes, datetime) 
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.

The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.
