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!
