and joins the cluster quickly (within one second is default), the config
change messages will not indicate that the node left and rejoined. The patch
introduces a short delay in main() to make sure the token_timeout expires.

The instantiaton of the component is performed with some new steps:
1. SU invoke Comp to instantiate
2. Comp multicast a new event
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE
3. Comp receive the new event
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE
4. If the Comp is within the SU hosted on the node. The
component invokes
the clc_cli instantiate script to start the component
and start a timer
to supervise the start and registration of the component.
5. If the instantiation time elapse before the component has
registered himself
Comp is sending a new multicasted event
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE_TMO.
6. Comp receive
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE_TMO event.
7. The Comp presence state is set to
SA_AMF_PRESENCE_INSTANTIATION_FAILED
8. When all Components are in presence state
SA_AMF_PRESENCE_INSTANTIATED or
SA_AMF_PRESENCE_INSTANTIATION_FAILED the start or restart will
continue with
the assignment of load.
This implemntation means that the complete instantiation procedure
never will be endlessly waiting for a register. The
instantiation will
either turn out in a component instantiation failure or a success.
Hardening of the cluster start use case:
1. A clearer separation of the responsibilities between
amf_cluster and
amf_application.
2. A clearer interface and separation between amf_main (amf.c) and
amf_cluster.
3. A clearer interface and separation between amf_cluster
and amf_node.
4. A clearer separation of the responsibilities between amf_node and
amf_application.

2- On Solaris, the SA components executed have no names.
3- When killing the testamf1 component, it makes the aisexec process
crash on both of my nodes.
4- max priority for RR on solaris is 59.

README.amf now also includes a detailed list of what is currently
NOT implemented.
README.amf includes now, as before, a "demo example".

node has been started and its SUs has been instantiated.

asymmetrically distribute the SG:s among the Nodes.
2. strcmp bug fixes several *_find functions.
3. Minor bug fixes.

The call to gethostbyaddr() has been removed. This has been replaced by a
protocol where each node multicasts its hostname (obtained with gethostname()).
- "Logical AMF nodes"
The AMF node name is no longer a hostname. The saAmfNodeClmNode
configuration attribute of the AMF node is now the hostname. This config
attribute is now mandatory. The change to amf.conf file shows required changes.
- Some other AMF sync bug fixes

- when DEBUG compiled it does not use the new printer threads (printouts are not buffered)
- man page update
- openais.conf update

2. Improvement of the use case 'Amf node join'
3. Improvement to manage more than one SG within an Application.
4. Improvement to manage an arbitrary number of Csi-assignments associated
to the Csi

- 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.
