Fix for memory corruption in the restarted process stack. This stemed from the brute force method we were previously using. This commit fixes this by using a lighter weight solution focused in the r2 BML instead of above the PML. This is a more efficient and flexible solution, and it solves the original problem. In the process I pulled out the ft_event function in the tcp BTL and r2 BML into a set of *_ft.[c|h] files just to keep any updates to these code paths as isolated as possible to make merging easier on everyone. This commit was SVN r14371.
