The logic in that function is broken. Various NULL-checking bandaids for
guaranteed non-NULL variables didn't even help there.
This patch updates the function to check if a previous item exists
before fetching it instead of after. This makes all other tests
unnecessary.
In particular, it makes the check for an empty list unnecessary, because
for empty lists the only iter is the begin iter (and the end iter) and
so the new check catches that case.

This makes it >10x faster if more than a single value is requested
by not searching in the GSequence for every value and converting
the value from GValue to the real value type.
Fix a warning that occurs when the self->priv->values is NULL and
the code tries to retrieve an iterator from it. The warning was showing
up in the checks for the volume element.
When generating arrays of control changes timestamp variable was used instead
the local ts variable that we increment when stepping through the array.

Use gst_guint64_to_gdouble instead of gst_util_guint64_to_gdouble

When linearly interpolating integer types, round to the nearest int
by adding 0.5. Don't do it for float/double types.
Fixes the failing controller test on my machine, which is somehow
rounding differently than on the buildbots.

Implement a interpolation control source and use this for backward

Factor out the 'set' logic into gst_controller_set_unlocked for the

To make life of the interpolators easier always add a control point
at timestamp zero with the default value.
In the linear interpolator make things more obvious by better variable
naming (slope).
Implement cubic interpolation mode (by using a natural cubic spline)
and map the quadratic interpolation mode to this too (as quadratic
doesn't make much sense, see discussion on the list).
