Include broker status and ID in (almost) all logging messages.
Makes it much easier to track broker state and interactions.

Sundry other logging improvements including:
- Demote noisy messages to trace - connections from rgmanager status checks, searching for primary.
- Rationalise start-up messages.
- Improved queue state detail replicating subscription and queue guard initialization.
- Fail to prepare TX is error.
- Collect all primary TX errors into one.
- Fix status of catchup brokers in primary membership for logging.
- Add process name/PID info to client connection messages.
- Various minor message tweaks.

PrimaryTxObserver::prepare used to block pending responses from each backup. With
concurrent transactions this can deadlock the broker: once all worker threads
are blocked in prepare, responses from backups cannot be received.

This commit generalizes the async completion mechanism for messages to allow
async completion of arbitrary commands. It leaves the special-case code for
messages undisturbed but adds a second path (starting from
SessionState::handleCommand) for async completion of other commands.
In particular it implements tx.commit to allow async completion.

TxBuffer is now an AsyncCompletion and commitLocal() is split into
- startCommit() called by SemanticState::commit()
- endCommit() called when the commit command completes

TxAccept no longer holds pre-computed ranges, compute fresh each time.
- Avoid range iterators going out of date during a delayed commit.

Added TransactionObserver interface, called at each point in a transaction's
lifecycle. Currently only a single observer can be associated with a
transaction.

Added startTx, startDtx to BrokerObserver so plugins can observe transactions
starting and set a TransactionObserver.

- Replicate DTX state to new members joining.
- Use cluster timer for DTX timeouts.
- Incidental: quote nulls in qpid::Msg messages (XIDs often have null characters)

constants.rb: generate type code constants for AMQP types. Useful with Array.

framing/Array:
 - added some std:::vector like functions & typedefs.
 - use TypeCode enums, human readable  ostream << operator.

rubygen - fixed error in generation of exceptions for bad codes.

Patches from Manuel Teira.
It's not clear at this point whether there is a compiler problem with gcc that it does find
the symbols in the namespaces or SunCC that it doesn't!
