To prevent receiving vote from old membership ring id is sent to server
during init and replied back to client in every node list,
ask for vote reply and vote info messages.

Previously client was not force to use heartbeat. Because we have to be
able to detect dead client in qnetd, heartbeat setting is now forced.
Insted of set_option message, heartbeat is force to exists in init
message. This also means that
QDEVICE_NET_INSTANCE_STATE_WAITING_SET_OPTION_REPLY can be removed and
client is considered as connected after init_reply is received. So
currently, set_option is not used (but implementation of these two
messages still exists).

- Add support for cmap node list configuration change
- Add client side algorithms
- Check if currently received ring id in membership message
equals to last sent ring id
- Send config node list only if config node list really changes and not
after every reload
- Add tlv_ring_id_eq (replacing qnetd_algo_rings_eq) so it's usable in
client
- Move debug logs from algo-test into qnetd-log-debug.c and call them in
proper places (= logs are now algorithm independent)
- Fix memory leak in msg

Tie-breaker can be used in algorithm to decide if algorithm should
prefer highest, lowest or some concrete node id.

State used for informative only callbacks (quorum node list) and
possibly informative only callbacks (configuration node list). Client
doesn't change cast vote timer state.
