Fix T43473: mathtutils.geometry.interpolate_bezier returns only 2d coordinates

Revert "mathutils: let Vector.normalize() return the original length."
...
Please discuss changes to core mathutils functions first.
Changes like this should be considered and applied to all areas of the API (or not at all).
Missed quaternion, matrix normalize for eg.

mathutils: let Vector.normalize() return the original length.
...
The length has to be calculated for normalization anyway, and it is already
returned by normalize_vn(vec, size).

658fc3ddbc
New python submodule mathutils.interpolate for various mesh interpolation and weighting methods.
...
This module will contain mirrored functions for calculating and applying
weights for points on a mesh. This includes barycentric and UV weighting
and possibly more advanced global weighting such as harmonic weights.
The naming should follow this scheme:
<type>_{2d,3d}_{calc,apply}
e.g.
poly_2d_calc
poly_2d_apply
uv_3d_calc
...

PyAPI: add PyList_APPEND
...
This appends while giving ownership to the list, avoiding temp assignment.
This matches PyList_SET_ITEM which bypasses refcount's
Note, this also reduce code-size, Py_DECREF is a rather heavy macro.

mathutils: refactor instantiation
...
remove 'type' argument, very few mathutils objects are wrapped,
add new function for creating wrapped objects.
also fixes unlikely memory leak if the data-array can't be allocated.

Py Mathutils: add invert_safe() and inverted_safe() to Matrix.
...
Those two mimic our BLI invert_m4_m4_safe - they add a small offset to diagonal values,
in case org matrix is degenerated, and if still non-invertible, return identity matrix.
Org patch by me, final enhanced version by ideasman42, many thanks!
