rB568f0c7 added a recursion check that is supposed to prevent cyclic
cases where a group includes itself via dupli instancing.
The check function was descending into all groups nested inside the
target group - which works for single level recursion like in the test
case, but does not handle generic recursion. Basically it asked:
"is object X in the group already or in any instanced dupligroup?"
The new check instead asks:
"is group G dupli'd by X or any instanced subgroup thereof?"
which is what we really need to know.
The reported Freestyle warnings were due to wrong normals of filled faces at both ends
of a 2D extruded curve. The problem is detailed in the comment #19 of T39669.
The cause of the bug was an inconsistency in the use of vertex indices between
BKE_mesh_nurbs_displist_to_mdata() and init_render_curve() in the case of
DispList::type equal to DL_INDEX3.
This commit also fixes a related bug that the normals of filled faces were not inverted
when a scale of the curve object is set to a negative value (e.g., the Z scale was -1).

The Bullet 2.82 update uses a different method for ray casting that
seems incompatible with our older files. So, for now we just force the
vehicle physics to use the older ray casting method.
This updates the fix in rB27db75363, which had to be undone
because it broke other bevels.
It also fixes cases where edges went away went doing vertex
bevel on vertices with some wire edges.
Logic here was very stupid, texboxes would have their initial
locations scaled by font size but not their width/height.
Now its possible to change font size while keeping the textbox layout.
Other fixes
- tab character didn't work properly with textboxes.
- memory leak when VFontData was missing.
For now only disables scene render if all the layers are disabled, but scene
will still be rendered if it's used in compo, has enabled layers which are
not used by compo.
Current pipeline doesn't allow to handle such cases nicely, so leaving it
for later.
It was a regression since 5d49eff. Not really sure about proper solution
here, so used a bit workaround-ish way for now.
Hopefully new cloth will be landed after this GSoC anyway.
- underline faces had flipped winding by default.
- BKE_vfont_to_curve_ex disallowed 0 underline height (annoying when sliding value)
- disallow negative underline height since it flips underline direction (just change position + height)
Problem happens when removing a rigid body reference in a constraint,
and then jumping to the start frame right away. This will cause a full
rebuild of the rigid body world. However, the btRigidBodys are removed
before the constraints, and this leaves dangling pointers in the
btTypedConstraints, which causes corruption when deleting those
constraints later.
Fix for now is to explicitly delete constraints in advance when
rebuilding, while they still have valid btRigidBody pointers.
Ultimately the whole memory management and ownership of Bullet data
needs redesign. This is already happening in the particles_refactor
branch and could be ported to master separately:

ANIM_editkeyframes_refresh was testing handle selection as if those handles were transformed.
This is already handled by areas which need it,
so simply replace testhandles_fcurve -> calchandles_fcurve.
This was causing other bugs such as inserting a keyframe changing handles of unrelated fcurves.
