The ECMP group id and the member ids are written into the
lr_in_ip_routing and lr_in_ip_routing_ecmp logical flows, but they
were assigned from the order in which routes reached
en_group_ecmp_route: the group id was hmap_count() at creation time
and the member id was the insertion position. On a full recompute
the routes are walked in hmap order, while incremental processing
appends them in event order, so the same set of routes could get a
different numbering. Every forced or fallback recompute could then
delete and re-insert Logical_Flow rows in the Southbound DB even
though nothing had changed.
Derive the ids from hashes instead. The group id comes from the
group key, i.e. prefix, prefix length, route table, source or
destination route and source class, which does not change as members
are added or removed. The member id comes from the UUID of the
route's source row, its nexthop and its output port: a NAT or LB row
produces one route per path to the peer router, so the UUID alone is
not unique within a group.
When two elements derive the same id, all of them retry in the next
round with an id derived from their hash and the round number, so
that the ids only depend on the set of routes and not on the order
in which they were processed. The members are listed in the select()
action in id order for the same reason.
Besides making a recompute produce the same flows as incremental
processing, adding or removing a route no longer changes the ids,
and so the flows, of unrelated groups or members.
Fixes: 6979a96138a2 ("northd: Support I+P for group_ecmp_route engine.")
Fixes: 5395e12f247c ("northd: Drop traffic for ECMP group with "discard"
route.")

v4:
- Derive the ECMP group and member ids from hashes instead of sorting,
so that adding or removing a route doesn't change the ids of
unrelated groups or members (suggested by Rosemarie).
- Added a test with NAT and LB routes reachable over several paths,
whose ECMP members share their source row.
- Added ovn_strip_ecmp_ids(), ecmp_ids() and ecmp_member_id() for the
tests.
v3:
- Dropped nullable_strcmp() and the patch converting its callers.
- Removed the unused 'route_count' field from struct ecmp_groups_node.
v2:
- Moved nullable_strcmp() to lib/ovn-util.h and documented its NULL
handling.
- Clarified in ecmp_groups_node_cmp() that it can't return 0 for two
distinct groups.
