Review request for qpid and Gordon Sim.

Summary (updated)

QPID-4710: [AMQP 1.0] Support for transactions in qpid::messaging C++ client.

Repository: qpid

Description (updated)

- the basic interop_tests are passing on qpidd, not on active or java broker.
- this branch requires the proton examples branch, won't work on proton master till all the
blocking proton JIRAS for QPID-4710 are fixed.
- several tests are still failing including ha_tests, swig_python_tests, interlink_tests

QPID-4710: Added descriptor list to Variant with support in Encoder and PnData.

Required to support transactions, need to be able to create described lists.
Variant changes are source and binary compatible.

A Variant now has a Variant::List of descripors which can be numeric or string.
Nested descriptors are implemented by putting multiple descriptors in the list.

Other minor changes:
- Variant refactor: don't delete impl on every assignment.
- Add Variant constructors that take a string encoding.
  (new constructors, not defaulted arguments, so the change is binary and source compatible.)
- Growable buffer support for Encoder.
- Printing described Variant prints descriptors in form @descriptor value

QPID-4710: [AMQP 1.0] Support for transactions in qpid::messaging C++ client.

Implements the "transactoinal retire and settle immediately" option for
transactions as specified in AMQP 1.0 in the qpid::messaging C++ client.

Added messaging/amqp/Transaction.h,cpp: transaction logic
- communicate with coordinator, send declare/dischange messages.
- add tx state info to transfers and acknowledgements.
- Sync session after discharge.

Added interop_tests.py: transaction tests that can be run against any broker (env QPID_INTEROP_URL)

Fixes to existing client code:
- Fix use of pn_drain API in C++ client to work with C++ and Java brokers.
- amqp::Exception derive from qpid::Exception

Fixes to existing broker code:
- Incoming.cpp fix: start async completion before processing message.
- Delay accept of dischage message till commit is complete.
- newSession - handle failover during session creation.

QPID-4710: Additional transaction tests

Enable transaction tests in ha_tests over AMQP 1.0.

Minor fixes
- Only run interop tests if AMQP built.
- Skip interop tests if no URL.
- brokertest.py don't set default logging if QPID_LOG env vars set.
- brokertest.py Pass kwargs to broker() create function.
- qpid-receive: capacity should never be larger than message count.
