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).

- 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

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.

- Add cast vote timer (qdevice-net now really votes)
- In sync phase it's impossible retreive cmap config version so it's no
longer sent in membership node list
- Refactor qdevice-net
