Fix T59059: Blender crashing after adding particle system and dynamic paint (Brush).

Looks like this bug has been there since ages (at least present before
2.79 official release...).

Simplified #ifdef to not silently fail on certain platforms

added shape-based clusters

clustergroup object with meshes will now cut out clusters according to their mesh,
make sure mesh is subdivided enough for better results

GP: Add offset over surface

GP: Add missing initialization for surface projection

GP: Add support for drawing control points [wip]

Also renamed variables top, bottom -> start, end

fix attempt for having proper constraints with dynamic fracture again

"mixed" and "all" settings were basically not properly taken into account before

GP: Experimental test for Stroke project

GP: Cleanup typo

added new cluster trigger propagation feature and a couple of fixes

fixes for example for split to island crashs

User Interface: Add button color for indicating that the value differs from the interpolated one

One issue that especially newer users often run into is that they accidentally reset changes to the scene by switching frame without creating a keyframe first.

Therefore, this commit adds a new color that is used to draw properties if their current value differs from the one that would be set when switching to this frame.
This works both for existing keyframes as well as for currently interpolated frames.

Unfortunately the flags in but->flag are full, so I had to move the new flag to but->drawflag and pass that to all relevant functions.

I went with orange for the color since afaics it fits with the green and yellow that are currently used for keyframe states and since it's somewhat reddish to signify that there might be something to look out for here.

Merge branch 'blender2.8' into greasepencil-object

Fix merge errors.

Fix T51057 Modifiers lose bevel weight and crease

This is for 2.80 (though bug I mistakenly merged into was for 2.78.
Duplicate bugs T58127, T58411, T58440, and T58789 all fixed.
Bevel weights and crease are not real Mesh layers so get lost
on coversion of mesh to bmesh unelss the mesh's cd_flag member
tells the converter to create layers for them.
Most code the copies or partially copies meshes uses
mesh_new_nomain_from_template_ex, so copied the flag there.

GP: Allocate stroke memory only when required

Fix T58950: wireframe/orthographic/front/side/topview crash 2.8

Shrinkwrap: use polygon normals for flat faces in Align To Normal.

Hit normal originates from tesselated triangles and isn't the
actual normal used for shading of flat faces. Thus, it is better
to use the actual polygon normals when available.

Cleanup: style
