strbuf_split*(): document functions
Document strbuf_split_buf(), strbuf_split_str(), strbuf_split_max(), strbuf_split(), and strbuf_list_free() in the header file and in api-strbuf.txt. (These functions were previously completely undocumented.) Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Jeff King <peff@peff.net>
