Our preferred shared logging system is exported via the libqb library. As
a result, the corosync project no longer needs to export logsys.so and the
code can be directly included in the binary. The header file can also be
removed.

defaults in services.c) and can load another module to do the quorum
work (eg YKD which I've made more compliant too). All the quorum code
has been removed from sync.c. quorum.c is simply a shim later for the
coroapi, the main module is in vsf_quorum.c
There are coroapi calls to query quorate status and also to get
notifications when it changes.
I've included the testquorum.lcrso module in this patch because I think
it's really helpful for testing. It sets the quorum state based on an
objdb variable, this can be set or cleared using corosync-cfgtool

This patch causes the flow control state in the library to be set
properly when the flow control is turned off (disabled). Then it can be
read properly by the flow control apis.
This also fixes the case where the application is no longer sending
messages and it has already dispatched all its received messages
before flow control is disabled.
Also, CPG response messages with a TRY_AGAIN error did NOT contain
a valid flow control state value. This meant the library could get
stuck with flow control enabled (flow control was never enabled
for the EXEC, so no disable event occurred).
This case was hit when a new node was joining - sync_in_process()
resulted in a TRY_AGAIN for error cpg_mcast_joined).
Also, in message_handler_req_exec_cpg_mcast() the state passed
back to the library defaulted to disabled for messages received
from another node (even if flow control was still enabled)
- this meant if multiple nodes were sending CPG messages,
then the library flow control state flip-flopped between
enabled and disabled.

confdb subsystems.
This is useful to provide atomic counters (ag handle numbers) for
long-running (though not persistent) connections. It's not currently
possible via confdb to atomically get a new number from objdb due to the
lack of locking. Doing it via increment operations in the IPC thread
provides enough atomicity to make it useful. Fabio has already
identified a use for these calls.
It could also provide some form of basic co-operative locking mechanism
for IPC-using processes (not direct objdb calls).

the confdb library to use the new find_create/find_next/find_destroy API
calls instead.
I've kept the libcondfb API the same as before with the single change of
adding a confdb_object_find_destroy to tidy up the find handle after
use. If you don't call this then libcondfb will do it for you when
confdb_finalize is called.
