adds a couple of new features:
- When total_votes exceeds the expected_votes value then expected_votes
is increased to that value.
- A callback can be sent to a client whenever expected_votes is changed

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

module doesn't provide quorum itself, merely a framework for setting and
querying it. I envisage YKD plugging into this rather than straight into
sync() eventually.
I've plugged this into the sync() routines rather than replacing them so
that quorum is itself a VSF, rather than a replacement - I'm not sure if
that is best or not. Opinions are welcome.
I've added an extra enum member to the service_handler so that we can
send IPC messages when the cluster isn't quorate. This will default to
NO (as now) but allows us to query and set quorum when we don't have it
.. a useful feature !

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).

Use a 2 phase "commit" operation:
1) Invoke verifyconfig that should catch the errors before the reload operation
2) Invoke reloadconfig that performs the operation and should _never_ fail
Implementation note: if step 2 fails, there is no fall back at the moment.

- AMF handles a component report of injurious health.
- AMF handles saAmfHealthcheckConfirm() SA_AIS_ERR_FAILED_OPERATION
so that if it's a recent recovery ongoing amf does nothing but if it's
no immediate recovery in progress, AMF invokes the recovery action
specified by the component when the health check is started If
the individual recommendation was SA_AMF_NO_RECOMMENDATION,
then AMF uses the configured recovery action for the component
(saAmfCompRecoveryOnError). If this recommendation also is
SA_AMF_NO_RECOMMENDATION, then AMF makes a component restart or
component/SU fail over counts on the value of
saAmfCompDisableRestart and saAmfSUFailover.
- Handling of cleanup of a component and health check response hardened.
- Time supervision and check return value of clc-cli CLEANUP command.
- Handle 'recommended recovery' specified by a component in an error
report. The potential recovery action to choose
implemented is - component restart - and - node fails over.
- The attribute saAmfCompDisableRestart is now recognizable which means
that if the component specifies 'Component restart' and restart is
disabled
then the SU in which the component is contained shall fall over.
- The attribute saAmfSUFailover will not be recognized. SU will always
fail
over as a single entity.
- A component can report an error on another component than itself.
- Implementation 'Instantiation Level' according to chapter 3.9.2 in the
AMF specification.
- Implementation of the escalation levels, component restart, SU
restart, SU fail over and Node fail over.

- One AMF node reads the AMF config file (IMM style)
- One AMF node syncs others AMF nodes
- One AMF object is serialized and sent as one message
- Serialization/deserialization of most objects is trivial (memcpy)
except for component and csi-attributes objects which have variable size
arrays/strings.
- Depth first AMF object tree traversal preserves relations when syncing
- Ordered lists of SUs and SIs
- Constructors/destructor per class
- Serializers/deserializers per class
- Config-change changes sync state
- Sync callbacks executes the sync
- "Use case" tracing for sync using the SYNCTRACE macro (trace6)
- Sync master is initially the winner of a timeout race and if the
master leaves the cluster, the node with the lowest node ID becomes new master.
- amf_malloc implements an AMF central malloc routine with error handling.

more fundamental information. (improves consistency)
- sg_assign_si can now recalculate workloads considering existing

- Logging improvements, similar to what is required as notification in
AMF spec.
- CLC-CLI INSTANTIATE now exits aisexec when it fails (should later be
sent as an NTF alarm)
- CLC-CLI CLEANUP correctly handles already terminated processes
- testamf1.c printouts removed for normal operation
- Iterator functions for SI/CSI assignments

model). A central header file (amf.h) keeps all the definitions and
prototypes needed.
New things apart from that:
- some doxygen html generated from AMF e.g. each file has a description
- saAmfHAStateGet() now works
- component invoked healthchecks implemented (but not tested)

- Use of Distinguished Names (DN) in API and multicast messages
- CSI resassignment properly handled (by using restarting state)
- State 'setter' functions with uniform printouts
- Simple 'assign SU to host' algorithm:
- based on saAmfSUHostedByNode config attribute
- see config file for example
- Debug print runtime attributes upon user request:
$ pkill -USR2 aisexec
- Object-oriented naming of functions started (but not finished)
- testamf1.c updated with some new tests
- Minor fix in print.h and print.c
- AMF can be started on two nodes (example config file needs
modification for this)

This small patch (against r948) adds variable CPPFLAGS to all make rules
that compiles `.c' files into `.o' files.
This makes it possible to set CPPFLAGS on the command line as in:
$ make CPPFLAGS=-DAMFDEBUG
Editing the makefile when prototyping is then not needed.
Another reason is that some of the openais C files are built using the
implicit rule for C files (which uses CPPFLAGS). The change makes rules
consistent with the implicit rule.
It also adds a few missing files to the clean make target.

tests results.
The changes may affect applications currently using the event service.
1. Timeout value to the saEvtChannelOpen call was updated to use
SA_TIME_MAX instead of 0 for infinite timeout.
2. added cleanup in the library to remove associated events when a
channel is closed, and remove associated channels when finalize is
called.
3. Added some new checking args for NULL and returning the correct error
code.
4. fixed dispatch to return correct status with SA_DISPATCH_ONE and no
available poll data.
5. Makefile had bad dependency for evt library build.
