 - 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.

after voluntary suspend() or network failure. Frames lost in network
failure are automatically re-transmitted for transparent re-connection.

client::Session improvements:
 - Locking to avoid races between network & user threads.
 - Replaced client::StateManager with sys::StateMonitor - avoid heap allocation.

qpid::Exception clean up:
 - use QPID_MSG consistently to format exception messages.
 - throw typed exceptions (in reply_exceptions.h) for AMQP exceptions.
 - re-throw correct typed exception on client for exceptions from broker.
 - Removed QpidError.h

rubygen/templates/constants.rb: 
 - constants.h: Added FOO_CLASS_ID and FOO_BAR_METHOD_ID constants.
 - reply_constants.h: Added throwReplyException(code, text)
 
log::Logger:
 - Fixed shutdown race in Statement::~Initializer()

	  a shared_ptr to a heap-allocated AMQBody subclass, it holds the
	  body in-line in a boost::variant of all the concrete AMQBody
	  subclasses. Actually there are nested variants, the compiler
	  does not cope well with a single variant of 130-some types.

	  Creating, encoding and decoding a local Frame doess 0 heap
	  allocation apart from that done by the concrete
	  AMQBody::encode/decode - e.g. method bodies with std::string
	  fields.  for method bodies

	  All variants contain type boost::blank. This guarantees 0 heap
	  alloocation by the variant and represents the "uninitialized"
	  state. variant.h provides NoBlankVisitor to help write visitors
	  for variants containing blank. 
	
	* src/qpid/framing/MethodHolder.h, .cpp: Holds a variant
	  containing a method body. 

	* src/qpid/framing/Frame.h, .cpp: New Frame holds body in a
	  variant rather than via heap allocation.

	* src/qpid/framing/variant.h: Utilities for using boost::variant.

	* src/qpid/framing/amqp_types.h: Added FrameType typedef.

	* src/qpid/framing/AMQMethodBody.h: Friends with MethodHolder.

	* src/Makefile.am:
	 - Improved ruby generation rule.
	 - Run method_variants template.
	 - Added new source files
	 - Pre-compiled header rule for method_variants.h

	* rubygen/templates/method_variants.rb: Generate variants
	  to hold methods of each class, and MethodVariant to hold all
	  the class variants.

	* rubygen/cppgen.rb: variant, tuple methods.

	* MethodBodyClass.h.tmpl: Added default constructor to method bodies.

	* amqpgen.rb (AmqpRoot::merge): fix bug in merge.
