[ODE] ODE changes

[Colin Bonstead]

Hey Russ, VC7 popped up a warning after the dInfinity change.  On line 
148 of collision_trimesh_sphere.cpp a float is set to dInfinity.  Since 
I'm compiling with doubles, the compiler reports an "overflow in 
floating-point constant arithmetic".  That whole function uses floats 
instead of dReals, so it's not as simple as just changing that one value 
to a dReal.  Maybe just change dInfinity to FLT_MAX there, since they're 
explicitly using floats anyway.  I don't know if that overflow actually 
causes any problems, but it would probably be worth getting rid of.

Also, I noticed odecpp_old.h is still lingering around, might want to 
get rid of that too.

i've checked in a number of changes:

* changed the way that the dInfinity constant is implemented: now it
  is #defined to be one of: FLT_MAX, DBL_MAX, HUGE_VAL, HUGE_VALF, or
  a large numeric constant. previously it was a variable that was
  exported from the library. this simplifies the configuration and
  build process quite a bit, especially in the case of DLLs.

* removed the old, deprecated collision system (geom.cpp,space.cpp,
  geom.h,space.h,odecpp_old_collision.h). the ODE_OLD_COLLISION
  configuration setting no longer has any meaning.

* removed support for dGeomGroups, which have been deprecated for
  a while and are equivalent to 'spaces' anyway.

NOTES
-----

i've updated the files in the VC6 directory, but haven't had the 
opportunity to test them.

i've updated the config.h in contrib/Mac_CFMCarbon, but i'm not sure if 
it works.

i have NOT fixed contrib/msvc7.
