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.

Don't access invalid mem in totemconfig interfaces

When ringnumber in config file was set to value bigger or equal to
INTERFACE_MAX, we are using this big value as index to totemconfig
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.

Use unix socket for local multicast loop

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).

it's probably because of firewall.
