04ac73018e qnetd: Add support for qnetd algo timer
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.

6c1add2925 Improve qdevice
- 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

8c0a45de41 qnet: Add TLV_VOTE_NO_CHANGE
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.

b1504098f4 qnetd: Make it easier to add algorithms
Put the algorithms into an array of structure pointers
(a bit like corosync services) so we can easily add more
without having huge switch statements.

I haven't added any code to the client end that parses the
name into the enum. Yet.
