[development] module_exists vs. functions_exists?

I think you're correct in using this; but only for hooks.  You've 
stated 'api_function' when it is actually the 'hook'.  And if 
mymodule_myfunction isn't a hook should we be using module_invoke to do 
the call?  No, we should call the function directly.
