The returned value is the number of addresses, or a negative error code;
the names and addresses are returned into the provided pointers as
consecutive null-terminated strings. It is up to the caller to free them.
Note that some of the strings may be zero-length.
Either of the provided pointers may be NULL if the caller is not interested
in those components.
quote_names_p and quote_addrs_p control whether the returned strings should
be quoted as RFC822 entities, or returned in a more human-presentable (but
not necessarily parsable) form.
If first_only_p is true, then only the first element of the list is
returned; we don't bother parsing the rest.
