These changes were the result of my Motion leak audit.
However, there is a serious problem with LLKeyframeMotionParam
in that it stores plain pointers to objects that can and will be deleted
by other objects. Its the classicial LL example of coding
non-Object-Oriented badly maintainable and instable code.
I cannot make sure this won't go wrong for the simple fact
that LLKeyframeMotionParam is not used at ALL in our code.
Hence, the next commit will rather delete this file.
This commit is merely to have a record of this finding.
