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
message), we can end up with assert, because my_failed_list and

build: fix indirect linking vs rpath by linking --as-needed
libtotem_pg links against libnss/nspr and correctly sets RPATH
corosync links against libtotem_pg, but libtool (via .la) enforces
an extra layer of linking against libnss/nspr without setting RPATH.
corosync final binary can't resolve the second linking and fails
to load.
This issue is visible only on NetBSD that enforces a much stricter
use of rpath (vs other OS/distros). Using --as-needed avoids that
and it's generally safe to use on other OS'es.
