Instead of each script defining their own ad-hoc usage function we define a generic handler in /bin/git/common.rc and have each script fill the $usage variable with a message that will get displayed on standard error output before exiting the program. This patch also makes an initial and weak attempt at cleaning up the usage messages to match the current implementation. Rest of the work, along with cleaning up the unused code paths will be done after further basic cleanups. Move usage handling to common.rc; update all scripts.
