The old springs with damping 1.0 operate in a special way that
is more similar to plastic deformation than a spring. Some users
rely on that, so let the user choose which implementation to use.
This also restores full backward compatibility with 2.79.

The new constraint is slower and not backward compatible, but should
be better, especially in the damping side. The new constraint also
has a different valid range of the damping coefficient, and a limit
implementation that bounces instead of making the object stationary.

This is a experimental collision detection function, so the API might
change in the future.
Note: The simulation needs to be stepped before this function can be
used, otherwise the rigid body world might not be valid.
Patch [#34989] Bullet Convex sweep test API
by Vilem Novak (pildanovak), thanks!
It's implemented as a separate constraint instead of adding properties
to the existing constraints.
Motors only apply linear and angular impulses and don't limit the
movement of rigid bodies, so it's best to use them in conjunction with
other constraints to limit the degrees of freedom.
Thanks to Markus Kasten (markus111) for the initial patch.
This modules does not depend on any blender-specific data
structures or algorithms and due to our policy better be
placed to intern/
Shall be no functional changes, tested CMake and SCons on
Linux, hopefully other platforms will work as well.
P.S. SVN history shall be preserved for the files.
