Relevant issues #24507 and #24166

Hi @rgommers @ngoldbaum,

This PR adds lib.array_utils module as as public namespace which creates only local namespace.
Initially it hosts three functions:

  • byte_bounds (moved from np.lib.utils)
  • normalize_axis_tuple
  • normalize_axis_index

Thanks @mtsokol. This looks pretty good to me. One idea to consider: would it make sense to move what is now in array_utils.py to _array_utils_impl.py and make the content of a new array_utils.py only this:

from ._array_utils_impl import (
    byte_bounds,
    normalize_axis_index,
    normalize_axis_tuple,
)

That would make it pretty much bullet-proof again more accidental leaking in of stray objects.

Also, as we just discussed, these are the first time we expose normalize_axis_index and normalize_axis_tuple as public API, so they should show up in the html docs after this PR.

@rgommers Sure, I added these two functions to routines.other.rst file.

* Can you verify that the removal of `np.byte_bounds` is okay with `joblib` now?

It looks like joblib uses np.byte_bounds in two places and one np.NaN that has already been removed. I will created a PR to address it: joblib/joblib#1501

* Since this is the first new namespace, it may be useful to ping the mailing list and point them at [DISCUSS: Namespace for array creation/inspection utils? #24166](https://github.com/numpy/numpy/issues/24166) regarding the `array_utils` name. Can you do that?

Sure! I sent a message to the mailing list.

Given this adds a new public name to the API let's let this sit for a few more days to gather comments.

LGTM now. Everyone's comments have been addressed, and the email to the mailing list didn't get replies. So I think we're good here. I suggest we merge this in a day or two unless there are new comments.

Adding here that the .. versionadded:: 1.13.0 in the normalize_axis_* functions took me a while to figure out, since np.lib.array_utils didn't exist until 2.0 🙃

FWIW, the versionadded 1.13.0 are now deleted because it is uninterestingly ancient history anyway ;).
