This series fixes numerous segfaults in config API users, because they didn't expect *_get_multi() to hand them a string_list with a NULL in it given config like "[a] key" (note, no "="'s). A larger general overview at v1[1], but note the API changes in v2[2]. Changes since v7[3]: * A trivial documentation change to 3/9, to clarify which doc in config.h refer to what. As noted in the v7 discussion I think that config.h could use some larger cleanups in this area, but let's leave that for some future topic.
