Highlights of this release

scipy.ndimage improvements: Fixes and ehancements to boundary extension
  modes for interpolation functions. Support for complex-valued inputs in many
  filtering and interpolation functions. New grid_mode option for
  scipy.ndimage.zoom to enable results consistent with scikit-image's
  rescale.
scipy.optimize.linprog has fast, new methods for large, sparse problems
  from the HiGHS library.
scipy.stats improvements including new distributions, a new test, and
  enhancements to existing distributions and tests

Deprecated features

scipy.spatial changes
  Calling KDTree.query with k=None to find all neighbours is deprecated.
  Use KDTree.query_ball_point instead.
distance.wminkowski was deprecated; use distance.minkowski and supply
  weights with the w keyword instead.
Backwards incompatible changes
  Using scipy.fft as a function aliasing numpy.fft.fft was removed after
  being deprecated in SciPy 1.4.0. As a result, the scipy.fft submodule
  must be explicitly imported now, in line with other SciPy subpackages.
  scipy.signal changes
The output of decimate, lfilter_zi, lfiltic, sos2tf, and
  sosfilt_zi have been changed to match numpy.result_type of their inputs.
The window function slepian was removed.
The frechet_l and frechet_r distributions were removed.

Log message:
math/blas, math/lapack: Install interchangeable BLAS system

Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework.  This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.

This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.

Details:

Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages
Update math/blas and math/lapack MAINTAINER approved by adam@
OpenBLAS, cblas, and lapacke will follow in separate commits
Update direct dependents to use mk/blas.buildlink3.mk
Perform recursive revbump

Log message:
py-scipy: update to 1.5.2

Done to fix build w/ gfortran 10. "make test" was mostly OK except for
three tests that returned nan where inf was expected ...

Highlights of this release:
  wrappers for more than a dozen new LAPACK routines are now available
  in scipy.linalg.lapack
  Improved support for leveraging 64-bit integer size from linear algebra
  backends
  addition of the probability distribution for two-sided one-sample
  Kolmogorov-Smirnov tests

New features:
  Too many; see release notes at github.

Backwards incompatible changes:
  The output signatures of ?syevr, ?heevr have been changed from
  w, v, info to w, v, m, isuppz, info
  The order of output arguments w, v of <sy/he>{gv, gvd, gvx} is
  swapped.
  The output length of scipy.signal.upfirdn has been corrected, resulting
  outputs may now be shorter for some combinations of up/down ratios and
  input signal and filter lengths.
  scipy.signal.resample now supports a domain keyword argument for
  specification of time or frequency domain input.

Log message:
py-scipy: updated to 1.4.1

SciPy 1.4.1 is a bug-fix release with no new features
compared to 1.4.0. Importantly, it aims to fix a problem
where an older version of pybind11 may cause a segmentation
fault when imported alongside incompatible libraries.

SciPy 1.4.0 is the culmination of 6 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with ``python -Wd`` and check for ``DeprecationWarning`` s).
Our development attention will now shift to bug-fix releases on the
1.4.x branch, and on adding new features on the master branch.
