Code review comment for lp://qastaging/~phablet-team/network-manager/ofono-rm-unused-code

Also this code has *nothing* to do with any code run on the desktop.

The only way any of the deleted static functions could possibly be used is if they were referenced in a function table, which none of them are.

The rest of the changes are super straight-forward, private variables that aren't ever used after being initialized, and code that's commented out, or ifdef'd out.
