Export tables merged with BGP prefix hash
...
Until now, if export table was enabled, Nest was storing exactly the
route before rt_notify() was called on it. This was quite sloppy and
spooky and it also wasn't reflecting the changes BGP does before
sending. And as BGP is storing the routes to be sent anyway, we are
simply keeping the already-sent routes in there to better rule out
unneeded reexports.
Some of the route attributes (IGP metric, preference) make no sense in
BGP, therefore these will be probably replaced by something sensible.
Also the nexthop shown in the short output is the BGP nexthop.

Hash: iterable now per partes by an iterator
...
It's now possible to pause iteration through hash. This requires
struct hash_iterator to be allocated somewhere handy.
The iteration itself is surrounded by HASH_WALK_ITER and
HASH_WALK_ITER_END. Call HASH_WALK_ITER_PUT to ask for pausing; it may
still do some more iterations until it comes to a suitable pausing
point. The iterator must be initalized to an empty structure. No cleanup
is needed if iteration is abandoned inbetween.

The show-route CLI command now uses the route export API
...
In the multithreaded environment, it is not supposed that anybody
traverses the routing table as the CLI show-route was doing. Now the
routing table traversal is gone and CLI won't hold the table locked
while computing filters.

Allowed optimized exporting of a subprefix tree

Added an option for export filter to allow for prefiltering based on the

is simple:
export in <net> <filter>;

Import tables are stored as an attribute layer inside the main tables.

The separate import tables were too memory-greedy, there is no need for
them being stored as full-sized tables.

There were quite a lot of conflicts in flowspec validation code which
ultimately led to some code being a bit rewritten, not only adapted from
this or that branch, yet it is still in a limit of a merge.

Fixing FlowSpec validation for v3 internal API

Validation is called internally from route table at the same place where
nexthop resolution is done. Also accounting for rte->sender semantics
change (not a channel but the import hook instead).
