mathutils: added exponential map to Quaternion
...
Added conversion to and from exponential map representation. This
representation is useful for interpolation of > 2 quaternions, or in
PD controllers.
Implementation in C functions quat_to_expmap,
quat_normalized_to_expmap, and expmap_to_quat with Python API, unit
tests and documentation.
Added Quaternion.to_exponential_map() and Quaternion(3-vector) to
Python API.

Fix T42638: Roll angle inconsistent flip in edit mode.
...
Basically, `angle_compat_rad()` was completely broken -
example of result it could produce:
| new angle | compat angle | result
| -0.000000 | 3.141593 | -> 3.141593
... Where 0.0 (or 2 * PI) would be expected!

Issue was in BLI's rotation_between_vecs_to_quat(), which did not handled correctly cases where both vectors are colinear.
Patch by Campbell Barton and me.
Issue originaly tracked down by Yan Shi, many thanks!

744f691af4
Fix dual quaternion armature deform giving erratic results in some cases. Bug
...
was encountered in a Kiribati rig file.
The problem was actually in the matrix to quaternion conversion function. One
problem is that it was using the wrong matrix indices in case of an ill defined
matrix trace. Besides that FLT_EPSILON was too small to detect cases where
float precision becomes a problem.

BLI_math rename functions:
...
- mult_m4_m4m4 -> mul_m4_m4m4
- mult_m3_m3m4 -> mul_m3_m3m4
these temporary names were used to avoid problems when argument order was switched.

rename axis_angle_to_mat3_no_norm() --> axis_angle_normalized_to_mat3().
...
this matches closer to convention from existing functions - angle_v3v3() angle_normalized_v3v3().
also added assert to ensure argument given to axis_angle_normalized_to_mat3() is in fact normalized.

New implementation for twist brushes.
...
It has much better rotation and avoids the compression effect that old
twist brushes have. Also twisting is now non periodic, meaning you can
twist beyond 180 degrees. The amount of twist is also calculated
relative to the angle formed after first translating the mouse away from
the brush center.
