RRP doesn't exist any more so all the ring re-enable code is redundant.
I've removed it from the library and all the code that does anything,
but I've left the hole in the IPC just in case old libraries are
hanging around.

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.

(cherry picked from commit c56086c701)
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,
runtime.services and runtime.totem prefixes together with new knet
related. All stats are read only.

Option -P takes numeric value with same meaning
as nice or values min / max, meaning maximal / minimal priority (so
minimal / maximal nice value).
Scheduler / priority setting is moved in code so it is now executed
after logsys is configured so errors are logged.
Setting maximal priority is also used as fallback when realtime
scheduling is requested and sched_setscheduler fails.

Corosync layers don't need to know the knet MTU size - this way
corosync fragments buffers only when they get larger than the
KNET buffer size (64K) and knet fragments below that based on
the actual MTU and transport considerations.
It is also now possible to configure knet to use UDP or SCTP
transports in corosync.conf. This is currently done per-link
so if you have more than 1 link you need several interface{}
stanzas inside totem{} to make it use other than the default
of UDP. if it's useful I might add the option of a global
default.

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

Uidgid entries parsed from configuration files now has prefix
(uidgid.config.) so they are distinguishable from dynamically added
entries. Entries added from config file are pruned on reload if no
longer exists in config file (dynamic one stays unaffected). Also whole
uidgid.config. prefix is made read only.
This make PCMK work again after configuration reload is called.

This patch tidies the two state change callbacks and explains them
in the man page:
The difference between votequorum_nodelist_notification_t and
votequorum_quorum_notification_t is subtle but important.
The 'nodelist' callback is sent at the start of a cluster state
transition and contains the new ring_id and only the list of
nodes that are included in the sync state - ie only active nodes. No
quorum information is included this callback because it is not
available at that time.
The 'quorum' callback is sent after the cluster state transition has
completed and does contain quorum information.
In addition, the nodelist contains a list of all nodes known to
votequorum (whether up or down) and their state as well
as information about the quorum device attached (if any). quorum
callbacks will not be sent for qdevice up and down
events unless they affect quorum.
