some rayTest improvements in btDbvt::rayTestInternal, it avoids/reduces memory allocations during stack allocation (by sharing a persistent m_stack)
...
and rayTestInternal re-uses precomputed invRayDirection/signs.
also did some performance comparison with different ray-AABB test, from
http://jgt.akpeters.com/papers/EisemannEtAl07/
In short: it is faster, but it is not clear how to cull ray segments using ray slopes: when rays starts inside the AABB, we get a negative t value, but negatives also get false t-values...

Some changes in rendering, to get shadows for trimeshes
...
Add dynamic aabb tree (btDbvt) optimization for btCompoundShape/btCompoundCollisionAlgorithm
Add btTransformAabb util, todo: deploy it throughout the codebase

Pathnames between #include files that are intended to be used within application code should not depend on the paths to the subdirectories being known to the compiler because this will not always be the case when an end-user includes your headers.
...
Includes of files in the local hierarchy must not use <...> please stick with "..."

added very basic debug drawing for vehicle wheels, and updated raycast in world to do ray-aabb instead of aabb-aabb

merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches.
...
Still need to verify to make sure no unwanted renaming is introduced.
