When an interface disappears handle the resulting POLLERR
result from polling. Ignoring this will cause ndppd to go into
a hot loop.
This is a very simple fix that will make the daemon terminate.
- Netlink is disabled per default (compile with WITH_ND_NETLINK)
- Automatic loading of routes is only done if at least one rule
uses the "auto" setting.
Uses netlink sockets to learn the addresses on the proxied
interfaces so that NS packets can be replied to (with a NA)
when the address is present.

We need to send the NA back to the All Nodes Multicast address
rather than attempting to route to "::".

Dynamic interfaces, such as tunnel and ppp, do not exist
in the kernel until it's fully configured. If nd proxy
is configured on such an interface, the ndppd config for
this interface should be written only when the interface's
fully configured (ie, having a valid ifindex value in apteryx).
The patch ensures that the ndppd config only contains interfaces
that have a valid ifindex. This is done by watching the interface
ifindex node in apteryx and trigger the ndppd config update callback
when ifindex has changed.
To make ndppd not exit when the config file contains an interface
that is not yet created, ndppd is patched to treat fd-bind error
as a valid return code so that the program does not try to
proxy the interface and will continue to run.

Members are initialized in the order that they are declared in the class
definition not in the order they are written them in the initialization
list in the constructor. Fix the ordering.

* Fix a bug where pollfds would be changed while in the poll_all
loop. This issue didn't exist before 'auto' was implemented.
* Fix so 'auto' rules won't try to forward Neighbor Solicitation
Packages through proxy's interface.
* Some code cleanup.
* Fix so that "route-ttl" in ndppd.conf works
* Fix a typo in ndppd.conf.5
* Update "ndppd.conf" to reflect the big changes
* Fix a bug with config loader
* Fix so that "auto" will never forward a Neighbor Solicitation
Message out through the "proxy" interface
