Currently, staticd configuration is tightly coupled with VRF existence.
Because of that, it has to use a hack in NB infrastructure to create a
VRF configuration when at least one static route is configured for this
VRF. This hack is incompatible with mgmtd, because mgmtd doesn't execute
configuration callbacks. Because of that, the configuration may become
out of sync between mgmtd and staticd. There are two main cases:
1. Create static route in a VRF. The VRF data node will be created
automatically in staticd by the NB hack, but not in mgmtd.
2. Delete VRF which has some static routes configured. The static route
configuration will be deleted from staticd by the NB hack, but not
from mgmtd.
To fix the problem, decouple configuration of static routes from VRF
configuration. Now it is possible to configure static routes even if the
VRF doesn't exist yet. Once the VRF is created, staticd applies all the
preconfigured routes.
This change also fixes the problem with static routes being preserved in
the system when staticd "control-plane-protocol" container is deleted
but the VRF is still configured.

`config.h` has all the defines from autoconf, which may include things
that switch behavior of other included headers (e.g. _GNU_SOURCE
enabling prototypes for additional functions.)
So, the first include in any `.c` file must be either `config.h` (with
the appropriate guard) or `zebra.h` (which includes `config.h` first
thing.)

When the control plane protocol is created, the vrf structure is
allocated, and its address is stored in the northbound node.
The vrf structure may later be deleted by the user, which will lead to
a stale pointer stored in this node.
Instead of this, allow daemons that use the vrf pointer to register the
dependency between the control plane protocol and vrf nodes. This will
guarantee that the nodes will always be created and deleted together, and
there won't be any stale pointers.
Add such registration to staticd and pimd.
