staticd: fix nexthops without interface

When interface is not set in "ip route" command, CLI passes "(null)" as
an interface name instead of an empty string. The actual code in turn
uses "nh->ifname[0] != 0" to check if the interface name was set. Fix
the problem by changing the "(null)" string into an empty string when
populating the nexthop structure.

Revert "staticd: Accept full blackhole typed keywords for ip_route_cmd"

This reverts commit 76b2bc97e73874d882d5cf021972cfca84656cef.

This change is wrong for several reasons:
- it is backwards incompatible - previously it was always possible to
  create blackhole/reject routes using shortened versions of the words
  and it suddenly became impossible if there's an interface in the
  system with the same name
- it uses operational data for validation which is prohibited
- it doesn't really solve the problem with inability to create routes
  using interface names like `bla` or `rej`

We don't need to create an actual tree to print an empty tree, libyang
handles NULL just fine. The actual problem is that `yang_dnode_new`
creates a tree by validating it, and the validation creates all implicit
default nodes. Therefore, when called with "with-default" flags, instead
of getting an empty tree, we get a tree with all top-level default set.

Without this change when we change the route-map, we never reinstall the route
if the route-map has changed.

We checked only some attributes like aspath, communities, large-communities,
extended-communities, but ignoring the rest of attributes.

With this change, let's check if the route-map has changed.

bgp_route_map_process_update() is triggered on route-map change, and we set
`changed` to true, which treats aggregated route as not the same as it was before.

The previous commit has added a routing leak update when a nexthop
update is received from zebra. It indirectly calls
bgp_find_or_add_nexthop() in which a static route triggers a nexthop
cache entry registration that triggers a nexthop update from zebra.

Do not register again the nexthop cache entry if the BGP_STATIC_ROUTE is
already set.

bgpd: fix VRF leaking with 'network import-check' (3/4)

If 'bgp network import-check' is defined on the source BGP session,
prefixes that are defined with the network command cannot be leaked to
the other VRFs BGP table even if they are present in the origin VRF RIB
if the 'rt import' statement is defined after the 'network <prefix>'
ones.

When a prefix nexthop is updated, update the prefix route leaking. The
current state of nexthop validation is now stored in the attributes of
the bgp path info. Attributes are compared with the previous ones at
route leaking update so that a nexthop validation change now triggers
the update of destination VRF BGP table.

We may actually need to send CLI commands to mgmtd and another daemon at

only daemon this exception protects is staticd. But we don't actually

zebra: make vrf netns commands do nothing

These commands don't really provide any functionality. VRF is associated
with netns automatically based on its name, and it's not possible to
associate VRF and netns with different names with these commands:

- When trying to assosiate a VRF with an already existing netns with a
  different name:
  `NS /run/netns/test is already configured with VRF 1(test)`

- When trying to assiciate a VRF with a non-existing netns, so they
  become linked once the netns is created:
  `Invalid pathname for /run/netns/test: No such file or directory`

- When doing "no netns" to unlink the netns and link it back to the same
  VRF:
  `VRF 1 is already configured with VRF test`

- When doing "no netns" to unlink the netns and link it to another VRF:
  `Can not associate NS 4294967295 with NETNS /run/netns/test`

As shown above, not a single usecase is working. We can't remove them
completely to preserve backwards-compatibility, so just make them empty.

The main reason for this change is not to spend a lot of time trying to
figure out how to convert them to northbound.
