Add two new functions, string_list_split() and string_list_split_in_place(). These split a string into a string_list on a separator character. The first makes copies of the substrings (leaving the input string untouched) and the second splits the original string in place, overwriting the separator characters with NULs and referring to the original string's memory. These functions are similar to the strbuf_split_*() functions except that they work with the more powerful string_list interface.
