Please move this into a separate patch.  The function also needs to be 
renamed because there is code out there which attempts to call it if it 
exists (notably, in Firefox and Rust—you might not see it because some 
refactoring broke it and switched from C linkage to Rust linkage, so the 
function is never found).

Thanks,
Florian
