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.

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.

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 ='

This is a big update that removes RRP & MRP from the codebase
and makes knet the default transport for corosync. UDP & UDPU
are still (currently) supported but are deprecated. Also crypto
and mutiple interfaces are only supported over knet.
To compile this codebase you will need to install libknet from
https://github.com/fabbione/kronosnet
The corosync.conf(5) man page has been updated with info on the new
options. Older config files should still work but many options
have changed because of the knet implementation so configs should
be checked carefully. In particular any cluster using using RRP
over UDP or UDPU will not start as RRP is no longer present. If you
need multiple interface support then you should be using the knet transport.
Knet brings many benefits to the corosync codebase, it provides support
for more interfaces than RRP (up to 8), will be more reliable in the event
of network outages and allows dynamic reconfiguration of interfaces.
It also fixes the ifup/ifdown and 127.0.0.1 binding problems that have
plagued corosync/openais from day 1

Member active is used for sending "multicast" messages only to members
of ring. This reduces network load if some nodes are intentionally down.
Only regular multicast message load is reduced (messages sent by
totemudpu_mcast_noflush_send), because special messages (like hold
cancel, join message, ...) still have to be send to all members to
ensure correct behavior.

The UDPU transport is useful for those deployments which can't use multicast.
UDPU works by using UDP unicast, which is fully supported by every switch
manufacturer by default and doesn't rely on a functional IGMP implementation.
An example of the UDPU transport is contained in the corosync.conf.example.udpu
file which shows a 16 node cluster. This file should be copied to each node
in the cluster and IP addresses changed as appropriate.
Amended to remove dead udpu REUSEADDR socket option.
