Back when I put this together in 2015, ISO C11 was still reasonably new
and we couldn't require it just yet. Without ISO C11, there is no
"good" way (only bad hacks) to require a semicolon after a macro that
ends with a function definition. And if you added one anyway, you'd get
"spurious semicolon" warnings on some compilers...
With C11, `_Static_assert()` at the end of a macro will make it so that
the semicolon is properly required, consumed, and not warned about.
Consistently requiring semicolons after "file-level" macros matches
Linux kernel coding style and helps some editors against mis-syntax'ing
these macros.

1. Modifies the data structs to make the distance, tag and table-id
property of a route, i.e created a hireachical data struct to save
route and nexthop information.
2. Backend northbound implementation

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

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
