Fix T39210: Grid Fill is generating mesh that's inconsistent with selected edge loops
...
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!

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.

don't use a while loop when in compatible_eul(). this is a low level rotation function called in many places so better to avoid iterations.
...
checked this function against the previous method using random rotation inputs and compared results, while this isnt exactly the same the results are very close and acceptable in both cases, also checked baking actions that the resulting FCurves are good and give matching rotations.
