Jan Friesse 131cfbe4ae Refactor qdevice-net
- 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.
