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

jquery-ui is no longer bundled in git repo and is downloaded during
the install or sdist process. If you are installing from pypi the
files will be included, but if you are installing from git you will
need internet access the first time you run `pip install .`. The
install process tries to cache the files and will not need internet
access on future installations.

This is the second bug-fix release for the v3.0 series.
- Un-breaks basemap which was broken by partially restoring
private APIs for cartopy.

more 'safe' switching after auto-discovery, but before starting an event loop.
- Improvements to bounding box calculations.
- Provide the correct length for RcParams instances.

REL: v3.0.0
The first release of the Matplotlib 3.0 series
This is the first version of Matplotlib to only support Python 3.
Highlights of this release include:
- GUI backend is selected at run-time based on what toolkits are
installed. A GUI toolkit will not be selected on a headless
server.
- New cyclic color map *twilight*
- Improvements to automatic layout of titles, ticks, and GridSpec
- Many bug fixes!

Don't call fflush() on a read-only file pointer; it is an error on BSD
systems and causes the import of matplotlib.pyplot to fail.
