This required adding a lot of return values to two previously
'void' functions. I did two rather than just the one that was
needed because it seemed to make sense to do them both together.
Although these functions now return errors, they are probably
still ignored higher up. this really needs a comprehensive audit.

Before this, all knet messages, including debug, were sent
over the pipe from knet to corosync and filtered in corosync.
This was obviously a waste, so now we tell knet the logging
level we need from it and so only get the messages that the
user has requested.

Current we horribly over-use totempg_ifaces_get() to
retrieve information about knet interfaces. This is an attempt to
improve on that.
All transports are supported (so not only Knet but also UDP(U)).
This patch builds best against the "onwire-upgrade" branch of knet
as that's what sparked my interest in getting more information out.

Needs new knet crypto API.
If it's not available, then fall back to the old
API and forbid changing crypto while running.
To avoid us being dependant on the leader node, each
node sends its own crypto_reconfig_phase messages so
we can guarantee that the reconfiguration always completes
on each node.

To make finding victim of incompatible messages easier, IP of sender is
logged. Propagating IP in layers makes patch slightly larger.

This shrinks the srp_addr (and consequently every packet sent by
corosync) so that instead of containing loads of IP addresses to
identify a node, it just sends the nodeid.
This then allows us to make ring0 optional and replaceable when running
knet.
It also means that we need some other way of identifying the local
node in corosync.conf, so the nodelist.node.name entry is now mandatory
and is mapped to the local host using the same algorithm as used in
cman.
This code needs LOTS of testing as it touches a huge amount of totemsrp
and totemconfig.

Now we are using knet, it's possible to dynamically add, remove and
reconfigure links on the fly.
Also print 'n' for non-existant knet links. This will show up
only on loopback links >0. But it looks better than 'status ='
