config: if local node addr is wrong, fail with a sensible message
If no valid local address is found in corosync.conf then corosync
exits with: "parse error in config: No multicast port specified"
This is because of the config change for knet that always populates
the interfaces. The old error of "no interfaces found" was only
slightly better anyway IMHO.
This patch adds an explicit check that local_node_pos has been
set in icmap and uses that to determine if a valid local address
has been found.

In my enthusiasm for removing code while integrating knet I
also deleted the correct code for returning IP address for a node,
so that only the IP addres of the local node was ever returned.
This commit restores the the previous code.
Also, because we always return INTERFACE_MAX interfaces now (they don't
have to be contiguous) set ss_family to zero if that interface is not
in use so that downstream apps know and don't display a lot of 0.0.0.0

sync: Call sync_init of all services at once
This patch solves situation which can happen very rearly:
- Node B is running
- Node A is started and tries to create singleton membership. It also
initialize service S which tries to send message during initialization
- Just before node A finished move to operational state, it gets
Node B multicast message so moves to gather state
- Node A and B creates membership and moves to operational state and
sync is started
- Node A and B receives message sent by node A during initialization of
service S
- Node A exits before sync of service is finished
In this situation, node B may never execute sync_init for
service S. So node B service S is not aware of existence of node A but
it received message from it.
Similar situation can theoretically also happen during merge.
Solution is to change flow of sync, so now it looks like:
- Build service_list
- Call sync_init for all local services
- Send service_list
- Receive service_list from all members and send barier
- For all services:
- Receive barier
- Call sync_activate if this is not first service
- Call sync_process for next service or finish sync if previous
this service is the last one
- Send barier

logsys: Avoid redundant callsite section checking
Previously, corosync executable was repeatedly (proportionally to the
count of LOGSYS_DECLARE_SUBSYS macro applications involved in the
constituent source files) checking the same for no gain in the pre-main
startup. This is not needed since nothing changes with static data
shared withing the same program space (it may have been a different
story once upon a time if loadable modules were in use), so make that
happen in (one-off per executable) LOGSYS_DECLARE_SYSTEM instead.
Libqb offers it's own ready-made macro to that
effect, simply to isolate the inner percularities from the library user
(that should not be required to understand anything about the orphan
sections and respective autocreated symbols to denote their boundaries).
As it is compile-time conditionalized in the same way, just use it
directly instead. As a value added, corosync will be kept up to date
about the possibly growing set of the logging-sanity checks as it gets
compiled with newer and newer libqb versions (their header files, for
that matter).

qdevice: Add support for heuristics
Heuristics are set of commands executed locally on startup, cluster
membership change, successful connect to corosync-qnetd and optionally
also at regular times. When all commands finish successfully
(their return error code is zero) on time, heuristics have passed,
otherwise they have failed. The heuristics result is sent to
corosync-qnetd and there it's used in calculations to determine which
partition should be quorate.
Right know, there are some problems (bugs):
- Regular heuristics is supported only by ffsplit. This is not a
problem for clusters with power fencing, but deployments where
non-quorate partition continues to operate may see this as a problem.
- Qdevice-tool status doesn't contain detailed information about
heuristics.
- Qdevice-tool doesn't have a possibility to trigger heuristics
re-execute.

cmap: don't shutdown highest config_version node
Scenario:
1. node A starts corosync with config_version = 2, nodelist = {A, B}
2. node B starts corosync with config_version = 1, nodelist = {A, B}
corosync.conf(5) says the config_version option is "used to prevent
joining old nodes with not up-to-date configuration."
So expected outcome is:
* corosync on node A remains alive
* corosync on node B exits
Actual outcome is:
* corosync on node A exits
* corosync on node B exits
Explanation of actual behaviour:
* Host A will have cmap_my_config_version = 2 but
cmap_highest_config_version_received = 1, so will shutdown in
cmap_sync_activate because these are not equal.
* Host B will have cmap_my_config_version = 1 but
cmap_highest_config_version_received = 2, so will shutdown in
cmap_sync_activate because these are not equal.
Instead, node A should consider its own config_version in the
calculation of the highest config_version, i.e.
cmap_highest_config_version_received = 2, and so not shutdown
in cmap_sync_activate.

totempg needs to store the current message + any
overflow for the next message which can be up to (nearly) the MTU size.
in knet that's large, but for UDP it's just 1500.
The reason we've never seen it before is because the actual max message
size is 1024 less than 1MB and after all the headers are stripped out the overflow is
usually 1024 bytes or less.
The 1024*1024 size of the assembly buffer is large enough to hold a max message (1047552) +
1024 bytes of a new UDP message. So we never saw any problems.
