Log message:
lang/python and a number of python packages: re-do atomic64.mk issue.

Evidently, python 3.13 brought in the need to support 64-bit atomics.
This means that python extension packages built with C needs to
use mk/atomic64.mk to make -latomic available on the required 32-bit
ports.  Sadly, there is no reliable way to detect in the .mk files
whether the package is using C (or C++), so this change adds an
unconditional include of mk/atomic64.mk when the python version is
equal to or larger than 3.13 for packages using egg.mk or wheel.mk.

This undoes the individual package Makefile inclusions of mk/atomic64.mk
that I've added over the last few days.

Log message:
devel/py-bitarray: use atomic64.mk to fix build on macppc w/python3.13.

py-*: remove unused tool dependency

py-setuptools includes the py-wheel functionality nowadays

Log message:
py-bitarray: updated to 2.9.3

2.9.3:
* add official Python 3.13 support
* update cibuildwheel to 2.21.3
* minor simplifications
* fix some typos

Log message:
py-bitarray: updated to 2.9.2

2024-01-01   2.9.2:
-------------------
* optimize initialization from strings by not constantly resizing buffer
* optimize `util.hex2ba()` and `util.base2ba()` by avoiding unnecessary
  copies
* optimize `util.base2ba()` and `util.ba2base()` for `n=16` (hexadecimal)

2023-12-23   2.9.1:
-------------------
* avoid buffer being unnecessarily initialized with 0s in several
  functions of the `bitarray.util` module
* fix `.count()` type hint in pyi-file
* improve testing

2023-12-17   2.9.0:
-------------------
* deprecate support for Python 2 - Python 2.7 support will be removed
  in bitarray version 3.0,
* `bitarray(n)` for integer initializer `n` will always return a bitarray
  of length `n` with all items initialized to `0`
* allow sub-bitarray in `.count()`
* add `util.ones()`
* `.find()` and `.index()`: add keyword argument `right` for rightmost index
* `.itersearch()`: add start and stop argument, and keyword
  argument `right` (for descending order - starting with rightmost match)
* deprecate `util.rindex()` (will be removed in 3.0 release),
  use `.index(..., right=True)` instead
* deprecate `util.make_endian()` (will be removed in 3.0 release),
  use `bitarray(..., endian=...)` instead

Log message:
py-bitarray: update to 2.8.5.

2023-12-09   2.8.5:
-------------------
  * speedup unaligned copies by always using word shifts (in combination
    with builtin byte swap 64 when available) when bit-endianness and
    machine byte-order are opposite
  * add `HAVE_BUILTIN_BSWAP64` to header
  * avoid misaligned pointers when casting to `(uint64_t *)`
  * add tests

Log message:
py-bitarray: updated to 2.8.4

2.8.4 (2023-12-04):

simplify copy_n() (remove special cases)
add word shift example C program, and simplify shift_r8()
improve documentation and testing
add roadmap

Log message:
py-bitarray: updated to 2.8.3

2.8.3:
* ensure readonly attribute is set correctly when creating new objects,
* optimize sparse bitarray compression for raw block type
* improve hash functions in Bloom filter example

Log message:
py-bitarray: updated to 2.8.2

2.8.2:
* update cibuildwheel to 2.16.1 in order to provide cp312 wheels on PyPI
* improve error messages for masked assignment
* simplify test collection
* added `pytest.ini` to allow running pytest with no additional arguments,
* `util.sc_encode()`: avoid writing empty blocks at end of compressed
  stream, ie. skip encoding when total population count is reached

Log message:
py-bitarray: updated to 2.8.1

2.8.1:
* use reconstructor function for pickling
* simplify implementation of `.reverse()`
