--enable-small-memory-footprint
When enabled the following defines are set
to reduce the overall memory footprint.

Currently totemip_copy (boundto,&ipaddr) is called even when the
required mask is not found.
This patch changes the behavior to only copy the ipaddr when the
mask is found.
The current behavior makes debugging an incorrect config really
confusing.

In logsys there are a number of XYZ_unlocked() functions that are called
like this:
pthread_mutex_lock (&logsys_config_mutex);
XYZ_unlocked();
pthread_mutex_unlock (&logsys_config_mutex);
The XYZ_unlocked() functions should not do any (un)locking.
But _logsys_config_subsys_get_unlocked() unlocks if it finds the subsys.
This means that there is 1 lock and 2 unlocks.

Attached patches handle NULL callbacks in *_initialize
and *_dispatch. Handling is same as in quorum service. Now, when
callback is NULL -> no memcpy -> instance callbacks will have all
items set to NULL and in *_dispatch function is not called.
It changes cfg so now we are using continue instead of exit.

Sometimes, when object_key_get doesn't return found_service_ver it
doesn't change old value and this value is then used in atoi what
will can cause fall of corosync. Patch fixes this case by setting
found_service_ver to NULL before call of object_key_get.

logsys thread priority was configured after forking the
wthread process and spread the scheduler priority config
across a large chunk of code in main.c
Now that logsys scheduler priority can be invoked at any time,
move the code together with corosync_setscheduler code.

logsys_thread_priority_set expects that wthread is already running
but doesn't perform any check if it is.
if logsys_thread_priority_set is invoked before forking the thread,
a segfault is guaranteed.
this changes to logsys_thread_priority_set ensure that a request
for a new scheduler priority is queued if the wthread is not
created yet and the new scheduler parameters are applied as early
as possible after the thread is created.
At the same time:
- add a few comments on clean up that needs to be done
- remove a redundant check for policy != SCHED_OTHER as that's
corosync need specific. logsys should simply accept the request
and apply it.

of the corosync version from users. Version and SVN

On some systems clock_gettime is not available so we are
testing availability and value of _POSIX_MONOTONIC_CLOCK.
On system without support of clock_gettime, we are using
old behaviour with function gettimeofday.

In case user not enter ver: in service section, whole
corosync falled with segfaul, because atoi was called
on NULL.
Now, in case of NULL, we rather not use atoi, and
return 0 directly.

The root of the theoretical problem is that cpg_join or cpg_leave
messages are being sent via the C apis between synchronization. With
the current cpg, synchronization happens in confchg_fn, and then later
in cpg_sync_process. cpg_sync_process is called much later after
confchg_fn and introduces a small probability of a window of time for
queued in totem (but not yet ordered by totem) for those cpg_join and
cpg_leave operations to interact with the synchronization process which
should happen in one atomic operation but currently is two distinct
operations.
This patch deletes confchg_fn and make sends joinlist/downlist
in cpg_sync_process.

This patch allows only one connection per (node, pid, grp_name) tuple.
This means, you cannot make more connection from one process to same
group_name. This is (I hope) how cpg should behave. In case, you will
try to do that, CPG_ERR_EXISTS error is returned.
Of course, there is no problem with creating:
- more connection with same (pid, grp) if nodeid is different
- more connection with same (node, grp) if pid is different (for example
after fork, or two distinct processes)
- more connection with same (node, pid) if grp is different (connect
one process to more cpgs).
