git-commit.sh: convert run_status to a C builtin
This creates a new git-runstatus which should do roughly the same thing as the run_status function from git-commit.sh. Except for color support, the main focus has been to keep the output identical, so that it can be verified as correct and then used as a C platform for other improvements to the status printing code.
