This patch returns back SUBJ functionality. It rely on fact, that
sendmsg will return error, and if such error is returned for long time,
it's probably because of firewall.

Instead of rely on multicast loop functionality of kernel, we now use
unix socket created by socketpair to deliver multicast messages to
local node. This handles problems with improperly configured local
firewall. So if output/input to/from ethernet interface is blocked, node
is still able to create single node membership.
Dark side of the patch is fact, that membership is always created, so
"Totem is unable to form a cluster..." will never appear (same applies
to continuous_gather key).

When ringnumber in config file was set to value bigger or equal to

interfaces array, resulting to access to invalid memory and segfault.
Instead of that, ringnumber is now checked and proper error message is
printed if value is too big.

Multithreaded corosync used to use many ugly workarounds. One of them is
shutdown process, where we had to solve problem with two locks. This was
solved by scheduling jobs between service exit_fn call and actual
service unload. Sadly this can cause to receive message from other node
in that meantime causing corosync to segfault on exit.
Because corosync is now single threaded, we don't need such hacks any
longer.
