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.

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.

- corosync-device-net as binary is gone. Replacement is
corosync-qdevice
- corosync-qdevice has support for multiple models (only net is
currently implemented)
- Completelly redesign qdevice-net main loop.
- Connect is non blocking
- Cmap and Votequorum events are handled even before connect to
qnetd. Algorithm gets send_node_list and vote set so it's not needed
to check connection status and also vote_timer is running and voting
until something changes (configuration or votequorum node list)
- If connect fails, algorithm_disconnected with new reason
CANT_CONNECT_TO_THE_SERVER is called
- Logging for qdevice is based on libqb logging functions. Also
logging configuration from corosync.conf is now used and dynamic
changes of configuration are handled.
- Added qdevice_net_algorithm_config_node_list_changed
- Changed qdevice_net_algorithm_votequorum_node_list_notify in respect
of adding send_node_list so it's similar to other functions.

- 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

- Add option for forcing ip version 4 or 6
- Choose new default port. It's now 5403. Exactly one less than used by
corosync.
- Fix compiler warning
