totempg needs to store the current message + any
overflow for the next message which can be up to (nearly) the MTU size.
in knet that's large, but for UDP it's just 1500.
The reason we've never seen it before is because the actual max message
size is 1024 less than 1MB and after all the headers are stripped out the overflow is
usually 1024 bytes or less.
The 1024*1024 size of the assembly buffer is large enough to hold a max message (1047552) +
1024 bytes of a new UDP message. So we never saw any problems.

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.

When initialization fails knet logs messages into pipe. Previously they

Man page of mlockall is clear:
Memory locks are not inherited by a child created via fork(2) and are
automatically removed (unlocked) during an execve(2) or when the
process terminates.
So calling mlockall before corosync_tty_detach is noop when corosync is
executed as a daemon (corosync -f was not affected).
This regression is caused by ed7d054e55
(setprio for logsys/qblog was correct, mlockall was not).
Solution is to move corosync_mlockall call on correct place.

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.
