BLD: Fix a macOS build failure when `NPY_BLAS_ORDER=""`

BLD: enabled negation of library choices in NPY_*_ORDER (#17219)

BLD: enabled negation of library choices in NPY_*_ORDER

When users build for a particular order it may be beneficial
to disallow certain libraries.

In particular a user may not care about which accelerated
BLAS library is used, so long as the NetLIB or ATLAS library isn't used.

This is now possible with:

   NPY_BLAS_ORDER='^blas,atlas'

or

   NPY_BLAS_ORDER='!blas,atlas'

Since we may envision more BLAS/LAPACK libraries to the pool, this
will provide greater flexibility as they enter.

A new (local) method is added in system_info.py which removes duplicate
code and allows for easier usage across libraries.

BUG: sysconfig attributes/distutils issue

2020-09-07T21:21:02+00:00

* gh-17223 started the `distutils` modernization
process because of the various upstream stuff
going on (thanks)

* that set of changes caused build issues with NumPy
pre-release wheels + SciPy `master`:
https://travis-ci.org/github/scipy/scipy/builds/725002838

* I was able to patch two separate issues and confirm
that this feature branch restores the SciPy build locally:
1) in one case, `distutils.sysconfig.get_python_inc` was
replaced with `distutils.get_python_inc`, which does not
exist (probably a typo)
2) a bit more serious; even `sysconfig.get_python_inc` does
not appear to exist; the closest match I could find (and
that worked) was `sysconfig.get_path()` with options for
general and platform-specific header paths as needed

* I'm not claiming that these stdlib replacements are perfect
either (the prefix case may still be slightly different?), but
it does prevent the SciPy build break originally introduced
as a start

BUILD: Remove Accelerate support (#15759)

2020-05-22T16:26:27+00:00

Remove support for Apple Accelerate, since it is buggy. A build error should
occur on most or all setups if linked against Accelerate. Test or import failures
should occur on setups where Accelerate is picked up dynamically.

MAINT: cleanup unused imports; avoid redefinition of imports

2020-02-06T09:16:23+00:00

* Cleanup unused imports (F401) of mostly standard Python modules,
  or some internal but unlikely referenced modules
* Where internal imports are potentially used, mark with noqa
* Avoid redefinition of imports (F811)
