libnm: add nm_ip_route_equal_full() function

Expose previously internal function nm_ip_route_equal_full(). It's
just useful API.

However, add a @cmp_flags argument, so that in the future we could
extend it.

 /**
- * _nm_ip_route_equal:
+ * nm_ip_route_equal_full:
  * @route: the #NMIPRoute
  * @other: the #NMIPRoute to compare @route to.
- * @consider_attributes: whether to compare attributes too
+ * @cmp_flags: tune how to compare attributes. Currently only
+ *   NM_IP_ROUTE_EQUAL_CMP_FLAGS_NONE (0) and NM_IP_ROUTE_EQUAL_CMP_FLAGS_WITH_ATTRS (1)
+ *   is supported.
  *
  * Determines if two #NMIPRoute objects contain the same destination, prefix,
  * next hop, and metric.
  *
  * Returns: %TRUE if the objects contain the same values, %FALSE if they do not.
+ *
+ * Since: 1.10
