BulletSim: default PhysicsTimeStep to same as the simulator's
...
heartbeat timestep when running the physics engine on a separate
thread. This reduces the occurance of heartbeats that happen when
there is no physics step which is seen as vehicle jerkyness.

BulletSim: fix corner case when rebuilding a compound linkset while

a mesh/hull while a mesh or hull is being rebuilt when its asset
is fetched. This fixes a 'pure virtual function' crash when changing
physical state of complex linksets that include many meshes.

BulletSim: experimental movement of physics execution off of heartbeat
...
thread. Off by default until more testing.
Setting "[BulletSim]UseSeparatePhysicsThread=true" causes the physics
engine to be called on its own thread and the heartbeat thread only
handles the reporting of property updates and collisions. Physics frame
rate is about right but physics execution time goes to zero as accounted
by the heartbeat loop.

...
if the mesh asset specifies physics hulls, BulletSim will fetch and
use same rather than approximating the hulls. If physics hulls are not
specified, the representation will fall back to the regular physics mesh.

BulletSim: enable GImpact shape for prims with cuts. Include DLLs and SOs
...
which recompute GImpact shape bounding box after creation as Bullet
doesn't do that itself (something it does for nearly every other shape).
Now, physical prims without cuts become single mesh convex meshes. Physical
prims with cuts become GImpact meshes. Meshes become a set of convex
hulls approximated from the mesh unless the hulls are specified in the
mesh asset data. The use of GImpact shapes should make some mechanical
physics more stable.
