AMQFrame contains a boost::variant of AMQHeaderBody,AMQContentBody,
AMQHeatbeatBody, and MethodHolder. A variant is basically a type-safe
union, it can allocate any of the types in-place.
MethodHolder contains a Blob, a less sophisticated kind of variant,
which can contain any of the concrete method body types.
Using variants for all the method types causes outrageous compile
times and bloated library symbol names. Blob lacks some of the finer
features of variant and needs help from generated code. For now both
are hidden to the rest of the code base behind AMQFrame and MethodBody
classes so if/when we decide to settle on just one "variant" type
solution we can do so.
This commit touches nearly 100 files, mostly converting method
signatures with shared_ptr<FooBody> to FooBody* or FooBody&, and
converting stored shared_ptr<AMQBody> to AMQFrame and
share_ptr<AMQMethodBody> to MethodHolder.
There is one outstanding client memory leak, which I will fix in my next commit.

- Wiring (declare/delete/bind) is replicated via AIS.
- TestOptions includes all logging options.
- Logger automatically parses env vars so logging can be enabled
for any program linked with libqpidcommon e.g. by setting QPID_TRACE=1.
* src/qpid/cluster/SessionManager.cpp: Handle frames from cluster
- Forward to BrokerAdapter for execution.
- Suppress responses in proxy.
* src/tests/TestOptions.h (Options): Logging options, --help option.

Logs are initialized either in TestOptions or automatically from env vars,
e.g. QPID_TRACE,
* src/qpid/QpidError.h (class QpidError): Initialize Exception in
constructor so messages can be logged.
* src/qpid/framing/ChannelAdapter.h: Made send() virtual.

* src/qpid/cluster/Cluster.cpp: Refactor - expose 4 handler points
for all traffic to/from cluster. Removed HandlerUpdater functionality,
separate class. Cluster only deals with membership and connecting
the 4 handler points to CPG multicast.
* src/tests/cluster.mk: Dropped newgrp ais wrapper scripts, its
much simpler if the user just does "newgrp ais" before building.
* src/tests/ais_check: Test script to check if users gid is ais
and give clear notice if not.
* src/tests/Cluster.cpp: Updated for changes to Cluster.
* src/qpid/cluster/Cpg.cpp: Better messages for common errors.
* Handler.h: Remove nextHandler() minor convenience is outweighted
by risk of undetected errors if handlers that expect next() to be
set are called when it's not set.
* src/qpid/cluster/Cpg.cpp: Added logging. Replaced boost::function
with traditional virtual interface (nasty stack traces.)

- Improved plugin framework and HandlerUpdater interface.
- Cluster handlers for traffic to/from cluster.
- Cluster HandlerUpdater configures channel chains for cluster.
- Cluster PluginProvider registers cluster objects with broker.
* src/qpid/framing/AMQFrame.h: Made data members public. Handlers
need to be able to modify frame data, getters/setters are just a
nuisance here.
* src/tests/Cluster.cpp: Updated for cluster changes, using
handlers instead of friendship to hook test into Cluster code.
* src/qpid/framing/amqp_types.h: Added CHANNEL_MAX and
CHANNEL_HIGH_BIT constants.
* src/qpid/framing/HandlerUpdater.h: Renamed ChannelInitializer,
broke dependency on broker channel types.
* src/qpid/framing/Handler.h: Added constructors and nextHandler()
* src/qpid/framing/AMQFrame.h (class AMQFrame): Inlined getChannel()
* src/qpid/cluster/ClusterPluginProvider.cpp: Provider for cluster
plugins.
* src/qpid/cluster/Cluster.cpp: Use ChannelManager. Factor out
plugin details to ClusterPluginProvider.
* src/qpid/cluster/ChannelManager.h: Insert cluster handlers
into channel chains, route frames between cluster and channels.
* src/qpid/broker/BrokerAdapter.cpp (startOk): use CHANNEL_MAX
constant.
* src/qpid/broker/Broker.cpp:
- Refactored for new plugin framework.
- Added getUrl().
* src/qpid/Url.h: Added constructor from Address.
* src/qpid/Plugin.h: Generalized plugin framework, broke
dependency on Broker interfaces. We may want to use plug-ins for
clients also at some point.
* src/tests/run_test: Fix bug when VALGRIND is not set.

* src/generate.sh: add cluster.xml to codegen.
* src/tests/Makefile.am:
- Generate individual "sudo -u ais" wrappers for openais tests.
- Drop "unit" directory, all unit tests in "tests" directory

* src/qpid/sys/posix/Socket.cpp:
* src/qpid/sys/posix/PosixAcceptor.cpp:
* src/qpid/sys/posix/EventChannelAcceptor.cpp:
* src/qpid/sys/apr/APRAcceptor.cpp:

* src/tests/.valgrind.supp-default: Suppress benign valgrind
warning in libcpg.
