Currently parse-options.o pulls quite a big bunch of dependencies. his complicates it's usage in contrib/ because it pulls external dependencies and it also increases executables size. Split off less generic and more internal to git part of parse-options.c to parse-options-cb.c. Move prefix_filename function from setup.c to abspath.c. abspath.o and wrapper.o pull each other, so it's unlikely to increase the dependencies. It was a dependency of parse-options.o that pulled many others. Now parse-options.o pulls just abspath.o, ctype.o, strbuf.o, usage.o, wrapper.o, libc directly and strlcpy.o indirectly.
