logging: Add CS_PRI_NODE_ID and CS_PRI_RING_ID

Previously node id was logged ether as a %d (most often), %u, %x or
PRI.32 and ring id ether as %lld, %llx with various separators (., :, /)
between rep nodeid and seq. This seems to cause confusion.

This patch adds macros CS_PRI_NODE_ID, CS_PRI_RING_ID and
CS_PRI_RING_ID_SEQ (CS prefix = corosync, PRI modeled in spirit of
inttypes.h PRIx32) and makes code use them.
