Subject: Session resume support in client & broker: Client can resume a
 session 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()
