[ODE] Reference counters

Reference counting adds significant memory traffic (especially if it's 
moderately thread-safe, and uses interlocked exchange).

My vote is that, if this gets added, it's added with an ifdef that 
defaults to off.

Also, the API for the user would have to change, as you'd need 
dBodyAddRef(), dBodyRelease(), and similar functions for each data 
structure returned from ODE.
