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).

Algo timer is simplified timer designed for qnetd algorithm. Instead of
full timer only one can exists per client. Workflow is:
- In one of algorithm callbacks qnetd_client_algo_timer_schedule is
called
- On timeout .timer_callback is called (for example
qnetd_algo_test_timer_callback). It's possible to set send_vote and
result_vote to send vote info to client
- It's possible to discard timer by calling
qnetd_client_algo_timer_abort
Timer is automatically deleted on client disconnect.
To make all this possible, qnetd main loop now has support for
timer-list (main_timer_list). To be able to handle error and disconnect
client from timer callback, client has schedule_disconnect. If this is
set to 1, client is disconnected on current call of poll loop.

- 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.
