IPv6 srcdest routes need to be keyed by both destination and source
prefix. Since the lookup order is destination first, the simplest thing
to do here is to add a second route_table to destination entries, which
then contain source entries. Sadly, the result is somewhat confusing
since a route_node might now be either a source node or a destination
node.
There are helper functions to get source and destination prefix from a
given route node (which can be either a destination or a source route).
The following bits have been added by Christian Franke
<chris@opensourcerouting.org>:
- make srcdest routing table reusable by moving it into lib
- make the srcdest routing table structure more opaque
- implement a srcdest routing table iterator
- fix a refcounting issue in src_node_lookup
- match route_node_lookup behavior with srcdest_rnode_lookup
- add accessor for the route_node table and table_info
- add string formatter srcdest_rnode2str

vector_remove would corrupt the data in the following sequence:
1. assume vector v = [a, b], active = 2
2. vector_unset(v, 0) => v = [NULL, b], active = 2
3. vector_remove(v, 1)
vector_remove calls vector_unset(v, 1), vector_unset notices index #0 is
also NULL and thus sets active to 0.
The equality test in vector_remove() now fails, leading it to decrement
v->active *again*, leading to an underflow that will likely crash the
daemon (and might even be exploitable).
This call sequence does not happen in existing code since vector_unset()
is not used on graph from/to lists. Nonetheless this is a buried land
mine in the code at best.
Rewrite the function - while we're at it, there's no reason to move the
entire array around, just fill the hole with the last element.

We don't need to copy the from/to arrays, we can just iterate backwards.
NB: this makes graph_remove_edge delete only one edge (which is more
consistent with graph_add_edge allowing parallel edges).
Iterating graph->nodes backwards also makes graph_delete_graph faster
since that also iterates backwards.
Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
Iterating over an array while deleting items needs to consider
interactions between the iteration position and deletion. The previous
code completely ignored that problem, leading to memleaks (graph_delete
skipping half of the nodes) and dangling pointers (if parallel edges
exist in graph_remove_edge).
Iterating backwards is safe and reduces "move to fill hole" overhead in
deletion.

command.c had:

DEFINE_MTYPE_STATIC(LIB, CMD_TOKENS, "Command Tokens")
... which means that there are 2 distinct MTYPE_CMD_TOKENS.
(The description text being different does not matter, even with the
same text it'd be 2 distinct types.)
command_match.c allocates token->arg in command_match_r() while
command.c frees it in del_cmd_token(). Therefore with each command
being executed, the allocation count goes up on one, down on the other.
=> clean up parser allocation counting. Also, use separate MTYPEs for
