The corosync message "A processor joined or left the membership" is
vague and unhelpful. People have to look for the following quorum
message and try to deduce which nodes have joined or left from that
and past membership messages, even though the routine printing the
message already has this information to hand.
This patch fixes that message so that it prints the nodeids of the nodes
that have joined/left the cluster.

Log: Output parse errors to syslog
When corosync was started in daemon mode and there was parse error, no
way existed how to find out what happened (this is usual situation with
systemd enabled systems). Solution seems to be output to syslog by
default.
Also redundant line with setting logsys is removed because it's no
longer needed, because FORK and THREADED mode options has no longer
effect. FORK is handled by libqb by default and THREADED mode is forced
by calling logsys_thread_start.

Remove unnecessary mmap in cpg
Code for zero-copy in cpg does following mmaps:
- Mmap anonymous, private memory to some address (-> malloc)
- Mmap shared memory of fd to address returned by first mmap
(effectively shadows first mapping)
This is not necessary and only one mapping is needed.

Detect big scheduling pauses
Add poll timer scheduler to be called 3 times per token timeout.
If poll timer was not called for more then 0.8 * token timeout, it means
corosync process was not scheduled and ether token_timeout should be
increased or load should be reduced (useful for VM, where host is
overcommitted so VM is not scheduled as expected).

Convert the nodeid byte order to be aligned with network order
When using corosync with clear_node_high_bit setting to yes,
the highest bit is cleared. When all the cluster nodes are in
one subnet, we probably configure the IP addresses as follows:
node1: 147.2.207.64
node2: 147.2.207.192
If the byte order of the nodeid is little endian, wiping off the
highest bit will make the two nodes have the same nodeid!
This patch fixes this by converting the nodeid to network order.

If failed_to_recv is set, consensus can be empty
If failed_to_recv is set (node detect itself not able to receive
