branch: use ref-filter printing APIs
Port branch.c to use ref-filter APIs for printing. This clears out most of the code used in branch.c for printing and replaces them with calls made to the ref-filter library. Introduce build_format() which gets the format required for printing of refs. Make amendments to print_ref_list() to reflect these changes. The strings included in build_format() may not be safely quoted for inclusion (i.e. it might contain '%' which needs to be escaped with an additional '%'). Introduce quote_literal_for_format() as a helper function which takes a string and returns a version of the string that is safely quoted to be used in the for-each-ref format which is built in build_format(). Change calc_maxwidth() to also account for the length of HEAD ref, by calling ref-filter:get_head_discription(). Also change the test in t6040 to reflect the changes. Before this patch, all cross-prefix symrefs weren't shortened. Since we're using ref-filter APIs, we shorten all symrefs by default. We also allow the user to change the format if needed with the introduction of the '--format' option in the next patch.
