/* NM_IP_ROUTING_RULE_TO_STRING_TYPE_IPROUTE gives a string representation that is
* partly compatibly with iproute2. That is, the part after `ip -[46] rule add $ARGS`.
* There are differences though:
*
* - trying to convert an invalid rule to string may not be possible. The reason is for
* example that an invalid rule can have nm_ip_routing_rule_get_from() like "bogus",
* but we don't write that as "from bogus". In general, if you try to convert an invalid
* rule to string, the operation may fail or the result may itself not be parsable.
* Of course, valid rules can be converted to string and read back the same (round-trip).
*
* - iproute2 in may regards is flexible about the command lines. For example
* - for tables it accepts table names from /etc/iproute2/rt_tables. We only
* accept the special aliases "main", "local", and "default".
* - key names like "preference" can be abbreviated to "pref", we don't do that.
* - the "preference"/"priority" may be unspecified, in which kernel automatically
* chooses an unused priority (during `ip rule add`). We don't allow for that, the
* priority must be explicitly set.
*
* - iproute2 does not support any escaping. Well, it's the shell that supports quoting
* and escaping and splits the command line. We need to split the command line ourself,
* but we don't support full shell quotation.
* from-string tokenizes words at (ASCII) whitespaces (removing the whitespaces).
* It also supports backslash escaping (e.g. to contain whitespace), but it does
* not support special escape sequences. Values are taken literally, meaning
* "\n\ \111" gives results in "n 111".
* The strings really shouldn't contain any special characters that require escaping,
* but that's the rule.
* This also goes together with the @allow_escaping parameter of nm_utils_strsplit_set().
* If you concatenate multiple rule expressions with a delimiter, the delimiter inside
* each word can be backslash escaped, and nm_utils_strsplit_set(allow_escaping=TRUE) will
* properly split the words, preserving the backslashes, which then will be removed by
* nm_ip_routing_rule_from_string().
