Two changes in this patch:
1) Management object IDs are now persistent for persistent (durable) objects. This is required to provide continuity of historical management data across broker restarts. The format of object IDs now indicates whether they are transient or persistent. The upper bit (bit 63) is 0 for transient IDs and 1 for persistent IDs.
2) Changes have been made to the management code generator in preparation for allowing it to be used by outside projects that wish to use the broker Plugin API for management access.
File-by-file notes:
M python/mgmt-cli/managementdata.py
Enhanced user-friendly display of 64-bit object IDs to
differentiate between persistent IDs and non-persistent IDs.
M cpp/src/Makefile.am
Changed command line format for call to the management code
generator.
M cpp/src/qpid/broker/Broker.cpp
M cpp/src/qpid/broker/Vhost.cpp
M cpp/src/qpid/broker/Queue.cpp
Updated calls to ManagementAgent::addObject to use the new support
for persistent IDs, ensuring that the management object IDs for
persistent objects are themselves persistent.
M cpp/src/qpid/management/ManagementAgent.h
M cpp/src/qpid/management/ManagementAgent.cpp
Added support (using defaulted arguments) to
ManagementAgent::addObject for persistent object IDs
M cpp/managementgen/generate.py
M cpp/managementgen/schema.py
M cpp/managementgen/main.py
Added the ability for templates to set variables to be used during
code generation.
Makefile fragment is now generated using a template rather than
hard-code. This was done to help non-qpid code to use the code
generator for management-via-qpid support.
M cpp/managementgen/templates/Args.h
M cpp/managementgen/templates/Class.cpp
M cpp/managementgen/templates/Class.h
Use a generator variable to define the comment prefix.
A cpp/managementgen/templates/Makefile.mk
New template for the qpid makefile fragment.

QPID-697
Fixed access-rights constants for management schema.
Added mutex to fix problems associated with concurrent invocation of accessors for queue statistics.
Removed queue schema content that is not relevant to QPID.
QPID-698
This patch creates a new subdirectory in python called "mgmt-cli".
python/mgmt-cli/main.py can be executed from the shell. If no arguments are supplied, it attempts to connect to the broker at localhost:5672. The first argument is the hostname for the target broker and the second (optional) argument is the TCP port (defaults to 5672).
It is assumed that the AMQP spec file is in the following location:
/usr/share/amqp/amqp.0-10-preview.xml
It is also required that the qpid/python directory be in the PYTHONPATH environment variable.

Queue statistics fixed. Additional objects added (exchange, binding).
Changes:
M cpp/src/qpid/broker/ExchangeRegistry.h
M cpp/src/qpid/broker/ExchangeRegistry.cpp
ExchangeRegistry was modified to pass a parent pointer to created
exchanges. This parent reference is not stored but is used to
link management objects in a hierarchy of ownership.
M cpp/src/qpid/broker/Exchange.h
M cpp/src/qpid/broker/Exchange.cpp
Exchange now inherits Manageable to make it visible via the
management interface. The Exchange parent class handles most of
the management boilerplate. A Binding struct was introduced to
track bindings for management. This is separate from
QueueBindings which track bindings for queues.
M cpp/src/qpid/broker/HeadersExchange.h
M cpp/src/qpid/broker/FanOutExchange.h
M cpp/src/qpid/broker/DirectExchange.h
M cpp/src/qpid/broker/TopicExchange.h
M cpp/src/qpid/broker/HeadersExchange.cpp
M cpp/src/qpid/broker/FanOutExchange.cpp
M cpp/src/qpid/broker/DirectExchange.cpp
M cpp/src/qpid/broker/TopicExchange.cpp
M cpp/src/qpid/management/ManagementExchange.cpp
M cpp/src/qpid/management/ManagementExchange.h
Each exchange type handles management stats in its own specific
way. Additionally, the constructors pass the management parent
pointer to the constructor or Exchange.
An extra layer was added to contain bindings. Instead of directly
storing bound queues, the exchanges store "bindings" which are
managable constructs.
M cpp/src/qpid/broker/Broker.cpp
Broker now explicitly enables the management agent. Also sets the
management parent (vhost) in the exchange registry.
M cpp/src/qpid/broker/Vhost.cpp
Updated constructor to be more defensive in case the management
agent has not been enabled.
M cpp/src/qpid/broker/Queue.cpp
Same constructor update as vhost. Moved accounting of dequeues
into "pop". Implemented management method handler (purge).
M cpp/src/qpid/broker/Deliverable.h
A new method was added to extract the content size of the
deliverable content (if appropriate). The method is not pure
virtual and returns zero if not overridden.
M cpp/src/qpid/broker/DeliverableMessage.h
M cpp/src/qpid/broker/TxPublish.cpp
M cpp/src/qpid/broker/DeliverableMessage.cpp
M cpp/src/qpid/broker/TxPublish.h
These derivatives of Deliverable were updated with overrides for
contenSize.
M cpp/src/qpid/management/ManagementAgent.h
M cpp/src/qpid/management/ManagementAgent.cpp
An "enable" method was added to prevent inadvertent creation of a
management agent when not desired.
Adding and deleting management objects is now protected by a
mutex.
Make sure that deleted objects get reported even if neither their
configuration nor instrumentation is changed.
M specs/management-schema.xml
Minor cosmetic updates. Additional parent linkage.
M cpp/managementgen/schema.py
M cpp/managementgen/templates/Class.cpp
Added generated code to publish schema details for methods.

- Uniform holder for all body types, replaces MethodHolder.
- Uses in_place constructors to avoid avoid body copy.
framing::AMQFrame:
- Holds body in heap-allocated intrusive_ptr<BodyHolder>
- Uses in_place constructors to avoid avoid body copy.
Removed/downgraded to TODO many redundant FIXME comments.
