The git_path function has "git_pathdup" and "strbuf_git_path" variants, but git_submodule_path only comes in the dangerous, static-buffer variant. That makes refactoring callers to use the safer functions hard (since they don't exist).
Since we're already using a strbuf behind the scenes, it's easy to expose all three of these interfaces with thin wrappers.
