added quickstep improvements, to allow for constraints (point to point etc).
...
Thanks Francisco Leon/projectileman

Based on feedback from another professional game company, there are several improvements, including some API change...
...
Some dynamic memory allocations have been replace by pool allocation or stack allocations.
quantized aabb versus quantized aabb overlap check is made branch-free (helps a lot on consoles PS3/XBox 360)
Collision algorithms are now created through a new btDefaultCollisionConfiguration, to decouple dependency (this is the API change):
Example:
btDefaultCollisionConfiguration* collisionConfiguration = new btDefaultCollisionConfiguration();
m_dispatcher = new btCollisionDispatcher(collisionConfiguration);

Attempts to improve performance. Not much gain yet, but good to experiment what has effect and what hasn't.
...
Added 'DO_BENCHMARK_PYRAMID' to CcdPhysicsDemo.

- removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal).
...
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015

updated quickstep solver (for comparison), enabled GPU physics again (but WIN32 doesn't have the VertexTextureSupport enabled)

Refactoring: another huge number of changes, renamed methods to start with lower-case.

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.

First stage in refactoring Bullet: moved Bullet Collision and Dynamics and LinearMath into src folder, and all files in Collision Detection and Dynamics have bt prefix.
...
Made all buildsystems to work again (jam, msvc, cmake)

Refactoring:
...
Moved optional code to Extras: AlgebraicCCD,EPA,quickstep
Moved SimpleBroadphase data to OverlappingPairCache, and derive both SimpleBroadphase and AxisSweep3 from OverlappingPairCache.
Added ParallelPhysicsEnvironment (prepair more parallel mainloop)
Upgraded hardcoded limit from 1024/8192 to 32766/65535 (max objects / max overlapping pairs)
