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.

Just gather the opaque data into the route entry. Later
commits will display this data for end users as well as
to send it down.

Initial WIP api to add providers into the zebra dataplane system,
with some simple ordering/prioritization.

Reduce or eliminate use of global zebra_ns structs in
a couple of netlink/kernel code paths, so that those paths
can potentially be made asynch eventually.
Slide netlink_talk_info into place to remove dependency on core
zebra structs; add accessors for dplane context block
Start init of route context from zebra core re and rn structs;
start queueing and event handling for incoming route updates.
Expose netlink apis that don't rely on zebra core structs;
add parallel route-update code path using the dplane ctx;
simplest possible event loop to process queued route'
updates.

The 'struct rib' data structure is missnamed. It really
is a 'struct route_entry' as part of the 'struct route_node'.
We have 1 'struct route_entry' per route src. As such
1 route node can have multiple route entries if multiple
protocols attempt to install the same route.

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.

This is a rather large mechanical commit that splits up the memory types
defined in lib/memtypes.c and distributes them into *_memory.[ch] files
in the individual daemons.
The zebra change is slightly annoying because there is no nice place to
put the #include "zebra_memory.h" statement.
bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the
library for its own use. This is bad practice and would break when the
memtype are made static.
