towards GPU joint (non-contact) constraint solving. The ConstraintDemo shows that CPU performance is very good, so not much performance win is to be expected.

Move b3Quickprof.* from Bullet 3.x src folder to btgui/Timing
...
The Bullet 3.x B3_PROFILE can be customized using b3SetCustomEnterProfileZoneFunc/b3SetCustomLeaveProfileZoneFunc defined in Bullet3Common/b3Logging,
so you can hook Bullet 3.x up to your profiler of choice.
The Demos3/BasicGpuDemo will show the Bullet 3.x timings inside the Bullet 2.x btQuickprof profiler.

tweak default values of b3Config.h so some laptop GPUs can run 128k scenes
...
return the result of resize
use size_t instead of int for btOpenCLArray
BasicInitialize demo will test how much memory can be allocated, using the btOpenCLArray

faster scene construction when not using instancing (avoid copy individual vertices/shapes to GPU, but do it afterwards in a batch), copy GPU data in 'writeAllBodiesToGpu' method
...
add option --no_instanced_collision_shapes, this only applies to the 2 benchmark screnes at the moment
always use the user specified b3Config file, so the settings can be set at runtime, not just at compile time
adjust default constants in b3Config (needs more tweaking, ideally at run-time)

b3GpuDynamicsWorld improvements:
...
apply forces
copy linear/angular velocity every frame at the CPU side, initial velocity works now
hook up setGravity
Note: the 'stepSimulation' for GPU only simulates a single simulation frame.
