I made a silly little script that looked at the defined symbols in nm and then looked to see if other files in the module used those symbols and if they didn't they were either candidates for removal or to be made static. This is the result.
I split the code into per-file chunks for easier review and to make it easier for the developers to object to any given removal but I have no qualms if Sean or Rob want to squash these together in the final patch.
