stdatomic.h does not have aliases for all of the useful gcc
atomic primitives; add them in for that path through
frratomic.h.

There exists a possibility that the ifindex we are passed
does not exist and as such we should check for it not
resolving as part of the debug.

It is possible to dynamically change default VRF name, if vrf backend is
a netns backend. By creating a link to the default netns in
/var/run/netns folder, then the file name will be used to name the
default VRF. If no backend netns is chosen, it is explained that it is
still possible to statically configure the default vrf name to new
define.

If default VRF is used, with standard naming convention,
memory allocation can be avoided.

Prevent from creating vrf, if the default vrf name is the same as the
vrf to be created.
Also, prevent at startup from creating default vrf with a name already
used in vrf list.

For the daemons that do not use vrf_init(), the call to the define
will return a default vrf if no other values has been overriden.

Because a VRF name can be used for default VRF, or an alias of an
already created VRF can be passed as parameter, the default VRF name
must be found out. This avoids creating double BGP instances for
example.

In the case the default netns has a netns path, then a new NETNS
creation will be bypassed.

The Vrf aliases can be known with a specific hook. That hook will then,
from zebra propagate the information to the relevant zapi clients.
The registration hook function is the same for all daemons.

End user was seeing this debug but we are not giving
the user enough information to debug this on his own.
Add a tiny bit of extra information that could point
the user to solving the problem for themselves.
