ab479c49d3 Issue #26494: Fixed crash on iterating exhausting iterators. 
Affected classes are generic sequence iterators, iterators of str, bytes,
bytearray, list, tuple, set, frozenset, dict, OrderedDict, corresponding
views and os.scandir() iterator.

2bf8993db9 Optimize bytes.fromhex() and bytearray.fromhex() 
Issue #25401: Optimize bytes.fromhex() and bytearray.fromhex(): they are now
between 2x and 3.5x faster. Changes:

* Use a fast-path working on a char* string for ASCII string
* Use a slow-path for non-ASCII string
* Replace slow hex_digit_to_int() function with a O(1) lookup in
  _PyLong_DigitValue precomputed table
* Use _PyBytesWriter API to handle the buffer
* Add unit tests to check the error position in error messages

772b2b09f2 Optimize bytearray % args 
Issue #25399: Don't create temporary bytes objects: modify _PyBytes_Format() to
create work directly on bytearray objects.

* Rename _PyBytes_Format() to _PyBytes_FormatEx() just in case if something
  outside CPython uses it
* _PyBytes_FormatEx() now uses (char*, Py_ssize_t) for the input string, so
  bytearray_format() doesn't need tot create a temporary input bytes object
* Add use_bytearray parameter to _PyBytes_FormatEx() which is passed to
  _PyBytesWriter, to create a bytearray buffer instead of a bytes buffer

Most formatting operations are now between 2.5 and 5 times faster.

861470c836 #16518: Bring error messages in harmony with docs ("bytes-like object") 
Some time ago we changed the docs to consistently use the term 'bytes-like
object' in all the contexts where bytes, bytearray, memoryview, etc are used.
This patch (by Ezio Melotti) completes that work by changing the error
messages that previously reported that certain types did "not support the
buffer interface" to instead say that a bytes-like object is required.  (The
glossary entry for bytes-like object references the discussion of the buffer
protocol in the docs.)

db067af12a Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(), 
PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) and bytearray(int) are now
using ``calloc()`` instead of ``malloc()`` for large objects which is faster
and use less memory (until the bytearray buffer is filled with data).

8455723cfb Close #19568: Fix bytearray_setslice_linear(), fix handling of 
PyByteArray_Resize() failure: leave the bytearray object in an consistent state.

If growth < 0, handling the memory allocation failure is tricky here because
the bytearray object has already been modified.  If lo != 0, the operation is
completed, but a MemoryError is still raised and the memory block is not
shrinked. If lo == 0, the bytearray is restored in its previous state and a
MemoryError is raised.
