f2c76aa6cb Issue #14687: str%tuple now uses an optimistic "unicode writer" instead of an 
accumulator. Directly write characters into the output (don't use a temporary
list): resize and widen the string on demand.

3a7f7977f1 Remove buggy assertion in PyUnicode_Substring()

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.

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()

 * don't duplicate the string if the length does not change
 * Use PyUnicode_DATA() instead of _PyUnicode_AsString()

7b1668735a don't use a slot wrapper from a different special method (closes #14658) 
This also alters the fix to #11603. Specifically, setting __repr__ to
object.__str__ now raises a recursion RuntimeError when str() or repr() is
called instead of silently bypassing the recursion. I believe this behavior is
more correct.

b0b224233e Issue #14385: Support other types than dict for __builtins__ 
It is now possible to use a custom type for the __builtins__ namespace, instead
of a dict. It can be used for sandboxing for example.  Raise also a NameError
instead of ImportError if __build_class__ name if not found in __builtins__.

fd0741555b Issue #2377: Make importlib the implementation of __import__(). 
importlib._bootstrap is now frozen into Python/importlib.h and stored
as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen
code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().

Currently import does not use these attributes as they are planned
for use by importlib (which will be another commit).

Thanks to Filip Gruszczyński for the initial patch and Brian Curtin
for refining it.
