A btBvhTriangleMeshShape object is created when converting
a mesh to physics, also in case of Soft body although the
soft body will not use it (it only uses the mesh interface).
This patch keeps this system for compatibility with the
KX converter but avoids the creation of the BVH structure,
which consumes a lots of CPU. This should speed up
significantly the conversion of large mesh to softbody.
A secondary optimization is that the sharing of shapeInfo
is extended to rigid body using gImpact. Before it was
only active between static body and soft body.
Even a static mesh can be used as replacement: the mesh
will be instantiated with the soft body settings of the
object. The position and orientation of the soft body
is preserved after the replacement.
Known limitation: the velocity of the soft body is reset
aftet the replacement. This is because soft body don't
have a well defined velocity.
* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
* further cleaning of 'player' stuff. Now only 3 libs are remaining, of which ideally the stubs lib will be fixed at some point, fading away into the dark history of not-so-nice code. The current blenderplayer part is still a little bit hackish, I'll see if I can find a better alternative, for now it works good enough.
* first working changes to get blenderplayer linking
* blenderplayer/ moved into source/ (CMakeLists.txt changed for that too)
* added externs for bprogname to gp_ghost, so that it links properly
* Add BGE_CXXFLAGS so we can get rid of hard-coded BGE compiler settings. This was only done for windows, but now linuxers and osxers should be able to set BGE-specific optimisation too. See the windows default configs for example.
Add support back for reinstancePhysics mesh, a frequently requested feature in the BGE forums.
from what I can tell Sumo supported this but bullet never did.
Currently only accessible via python at the moment.
- rigid body, dynamic, static types work.
- instanced physics meshes are modified too.
- compound shapes are not supported.
Physics mesh can be re-instanced from...
* shape keys & armature deformations
* subsurf (any other modifiers too)
* RAS_TexVert's (can be modified from python)
Moved the reinstancePhysicsMesh functions from RAS_MeshObject into KX_GameObject since the physics data is stored here.

* ensure all SConscripts are ready for win64-vc (where necessary).
* ensure we have proper _DEBUG flag for Python when we're doing a debug build.
* some cleaning up of linking etc.
* ensure /EHsc is there for game engine modules.
* removed radiosity render code, DNA and RNA (left in radio render pass options), we'll get GI to replace this probably, better allow baking to vertex colors for people who used this.
* removed deprecated solid physics library, sumo integrations and qhull, a dependency
* removed ODE, was no longer being build or supported
* remove BEOS and AMIGA defines and references in Makefiles.
Example is a cube that lands on a plane, sleeps after some time, a script changes the scale.
It would still use the scale when the object first went to sleep.

* Missing changes to release/windows/installer
* Sequencer fixes in source/blender/src/seqaudio.c dont apply to 2.5
* brechts fix for #18855 r20763 wasnt merged, does this apply to 2.5?
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
- Typo in occlusion variable init "m_buffer == NULL;" -> "m_buffer = NULL;"
CcdPhysicsEnvironment.cpp and CcdPhysicsController.cpp had too many warnings, fixed most of them.
+ fixed Python method, PyArg_ParseTuple already checks for errors, no returning of NULL, thanks Campbell too)
+ added linear/angular spring for each of the 6DOFs of a generic 6dof constraint. This makes the generic 6dof constraint very versatile.
allow to dynamically create rigid body constraints while disable collision detection between connected bodies, pass as 10th argument the flag 128
PhysiPython KX_ConstraintWrapper, setParam
export setParam(paramIndex,paramValue0,paramValue1) for Physics constraints
paramIndex 0,1,2 are linear limits, 3,4,5 are angular limits, 6,7,8 are linear motors, 9,10,11 are angular motors
For example:
disableConnectedBodies=128
cons = PhysicsConstraints.createConstraint(oid,rid,generic6dof,pivotInAx,pivotInAy,pivotInAz,angleX,angleY,angleZ,disableConnectedBodies)
#params 0,1,2 are linear limits, low,high value. if low > high then disable limit
cons.setParam(0,0,0)
I will provide an example .blend for Blender 2.49

(todo: expose this setting in World setting GUI)
Expose contact processing threshold in Advanced GUI, next to rigid body margin, called CPT.
Default to 1, makes rigid body stacking a bit more stable, smaller values makes sliding easier (at the cost of easier jittering).
Disabled for 'dynamic' objects that don't rotate, because characters etc. always need smooth sliding.
