1) I don't think so, unless pchip is related.
2) Perhaps. Is it useful?
3) No idea.
One thing to look out: based on a quick look, Akima interpolation is a
form of spline interpolation, so it is probably possible to represent
the result as a B-spline. If so, FITPACK's spline representation
should be used, i.e., the same (t, c, k) format as in splrep.
This allows reusing `splev` for evaluating the spline values, which
will make life easier later on when we clean up scipy.interpolate.
