files_transaction_prepare() and the functions it calls add strings to a string list without duplicating them, i.e., we keep the original raw pointers we were given. That is "ok", since we keep them only for a short-enough time, but we end up leaking some of them. Switch to duplicating the strings, so that affected_refnames does not leak memory. The original strings might still leak, but at least that can now be addressed without worrying about these pointers. No-one takes any pointers to the strings in the list (it is basically only used to check for set membership), so it is ok for string_list_clear to free them.
