    interpolationcontrolsource: add cubic_mono interpolation

    This new mode won't overshoot the min/max y values set by the
control-points.
    Fixes #754678
    API: GST_INTERPOLATION_MODE_CUBIC_MONO

    interpolationcontrolsource: refactor code

    Extract common code that looks up the control-points around the timestamp.
Add
    some comments for future investigation.

    tests/examples: add a demo for the interpolation control source modes

    This is in preparation for new modes to be added. In particullar it
demonstrates
    how the cubic splines overshoot the range.
