7df9b69039 pybullet: add option to use NumPy to speed up, thanks to moof2k
option is disabled by default. When using cmake, use
cmake -DBUILD_PYBULLET=ON -DBUILD_PYBULLET_NUMPY=ON
then both testrender.py and testrender_np.py will work
without numpy only testrender.py works.
The numpy.reshape is likely a no-op when using numpy array,
so we could remove testrender_np.py...

1c65cae6d0 [SharedMemory] Calculate inverse dynamics now uses world gravity.
Small change that takes the world gravity and applies it to the
body during the call to inverse dynamics in the shared memory
interface. Otherwise the gravity vector is left at the default
value and there is currently no interface to set the gravity
for the inverse dynamics system.

Add option to have Z as up-axis for VR examples.

Don't crash VR app when no HMD is detected, just exit.
For now, don't request debug lines in client, it slows down physics server in VR mode too much.

6c9ce344ea fix shadowmap crash on some Intel GPUs, see https://github.com/bulletphysics/bullet3/issues/4
remove targetdir from all libraries in premake, so it is much easier to create a separate folder for all binary+lib
transmit the serialized btMultiBody data back from server to client, after the server loads a URDF file. This includes base+link+joint names
tweak the serialization routines, so it is easier to skip pointers and to serialize directly to a shared memory buffer
also tweak the serialization code to allow to process data without 'DNA' schema data (assuming file-DNA = memory DNA)
