A nozzle device is a pseudo ethernet device that routes network
traffic through a channel on the corosync knet network (NOT cpg or any
corosync internal service) to other nodes in the cluster. It allows
applications to take advantage of knet features such as multipathing,
automatic failover, link switching etc.

Instead of compiling totempg as a shared library, compile all totem code
directly into corosync binary.
Main idea of having totempg which may be
used in other projects was nice, but never really finished (and as far
as I know no project were ever really using it). So at the end of the
day, we've end with huge amount of problems (need to pass new arguments
thru X layers, hard debugging, ...) without any real benefit.
For a future version, we may consider to revisit idea of split totemsrp
into well tested library without unrelated bits like transports/ip/...

Libcgroup is deprecated and not shipping with new distributions
(OpenSuSE is one example). Solution is to have a partial implementation
of required functionality of libcgroup in the corosync code.
Patch uses hardcoded cgroup mount point, because most of the systems are
now systemd and systemd is also using hardcoded mountpoint (see
https://github.com/systemd/systemd/blob/master/src/core/mount-setup.c)
Configuration option --enable-cgroup is gone, because it's not needed
any longer.
Big thanks to Christine Caulfield <ccaulfie@redhat.com> for example of
simplified implementation of cgroup management code primitives.

When corosync is started in environment where it ends in cgroup without
properly set rt_runtime_us it's impossible to get RT priority.
Already implemented workaround is to use higher non-RT priority.
This patch implements another solution. It moves corosync into root cpu
cgroup. Root cpu cgroup hopefully has enough RT budget.
Another solution was mentioned on ML
https://lists.freedesktop.org/archives/systemd-devel/2017-July/039353.html
but this means to generate some "random" values.

Icmap is factored out so it's possible to add other
maps for cmap. API call to switch maps from application
end is added.
Corosync-cmapctl is enhanced with -m option.
Stats contains all statistics previously found in runtime.connections,

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

The libtotem_pg library uses symbols from libqb, so it should be
explicitely linked with it. This doesn't cause problems for corosync
binary itself, as it is linked to both libraries, but can cause
problems if anything else links to libtotem_pg.so and automated
checkers can show this as a library problem.

corosync logging configuration logic is rather complex and in order
to make it simpler to reuse (at least within corosync/ tree)
we need to be able to use both icmap and cmap.
the patch might seem controversial, but it reduces heaps of code around
from qdevices (coming next).
It might be useful to consider moving this to a common shared library
but there aren't enough users yet and a shared lib would force
corosync to link with cmap (that we do not want at all costs)

there are several reasons for this:
1) evs is only partially implemented with no plans to complete it
typedef enum {
EVS_TYPE_UNORDERED, /* not implemented */
EVS_TYPE_FIFO, /* same as agreed */
EVS_TYPE_AGREED,
EVS_TYPE_SAFE /* not implemented */
} evs_guarantee_t;
2) evs has no users in any upstream distribution and no search
engine can find any other upstream using it.
3) the only reason (I was told) to carry around evs was that evs
receives the full ring_id struct from totem. This is only
partially correct because while the structures are prepared
to carry around those data, they are never transmitted from
corosync engine down the IPC line to the user.
CPG ring_id contains the exact same information and it's
actually less buggy (due to prototying of the info).
worst case scenario where a user really absolutely need libevs,
it can be easily reimplemented as libcpg wrapper and avoid
lots of code duplication.

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.
