added duplis as fracture "source"

this basically converts e.g. particle duplis to individual rigidbodies

dynamic fracture: fix for depsgraph thread jamming / crashes

the modifier eval thread made calls (validate shard) which changed the rigidbody thread's data from outside, before control is passed to rigidbody thread again (both tasks / threads follow each other alternatingly, first rigidbody, then modifier, then again rigidbody and so on after frames do change. Solution was to delay validation and let the rigidbody thread do it, instead of forcing it from the modifier thread.

dynamic fracture: when using constraints, keep those of unaffected shards in place

internally all constraints are removed just after bullet step, and rebuilt in modifier
eval call following it, so it will be there on next bullet step. else you mess up the sim
if you stop and restart it.

removed separate pack operator, execute fracture handles this now

removed accidental code merge failures

updated submodule pointers to match latest 2.8

Merge remote-tracking branch 'origin/blender2.8' into fracture_modifier-2.8

cleanup, removed (non-working) compound stuff again

cleanup, sensible rename and code documentation, first part

added dynamic shard count setting, to decouple from prefractured

fix for odd behavior with constraints and dynamic

was necessary to delete all constraints in each modifier evaluation when using dynamic

mainly fixing some warnings, further fix attempts for misbehavior with constraints/dynamic

some more dynamic fracture stability fixes

partial fix for bullet related crashes or lockups

especially when 2 or more dynamic objects fracture each other, there are still crashes / lockups

seems dynamic cache behavior is fixed, tests looked good .

execute fracture in dynamic should return the intact object

added constraint search size, made mixed/none constraint setting in dynamic work

plus fix attempts for dynamic cache logic

added separate activation shard size for dynamic fracture

exposed apply_force and apply_torque for rigidbody to python

using proper random number generator now + fixed dynamic trigger
