If a route-map in zebra has `set src X` and the interface
X is on has not been configured yet, we are rejecting the command
outright. This is a problem on boot up especially( and where I
found this issue ) in that interfaces *can* and *will* be slow
on startup and config can easily be read in *before* the
interface has an ip address.
Let's modify zebra to just warn to the user we may have a problem
and let the chips fall where they may.

Having a fixed set of parameters for each northbound callback isn't a
good idea since it makes it difficult to add new parameters whenever
that becomes necessary, as several hundreds or thousands of existing
callbacks need to be updated accordingly.
To remediate this issue, this commit changes the signature of all
northbound callbacks to have a single parameter: a pointer to a
'nb_cb_x_args' structure (where x is different for each type
of callback). These structures encapsulate all real parameters
(both input and output) the callbacks need to have access to. And
adding a new parameter to a given callback is as simple as adding
a new field to the corresponding 'nb_cb_x_args' structure, without
needing to update any instance of that callback in any daemon.
This commit includes a .cocci semantic patch that can be used to
update old code to the new format automatically.
