  1. ENH: Allow toggling madvise hugepage and fix default 

    By default this disables madvise hugepage on kernels before 4.6, since
we expect that these typically see large performance regressions when
using hugepages due to slow defragementation code presumably fixed by:

torvalds/linux@7cf91a9

This adds support to set the behaviour at startup time through the
``NUMPY_MADVISE_HUGEPAGE`` environment variable.

Fixes numpygh-15545

  2. DOC: Note few global global options we currently have in refdocs 

    These are options that are controlled typically through environment
variable at startup or compile time.
