Some extra initialization needs to occur before calling the local/remote GetFunctioneName. Also, cleanup the test code a bit: - Make all local functions static. - Create a common function to create and finish remote processes. - Remove unused function. - Fix the formatting a bit by making it match clang format. Test: Ran the unit tests. Change-Id: I998bed1378d582df59fdf9263df6f208db5d795a
