Description of problem:

AMQP 1.0 qpid::messaging c++ client unable to GSSAPI authenticate - SIGSEGV deep in infinite (mutual) recursion involving
  qpid::messaging::amqp::ConnectionContext::canEncode()  and
  qpid::sys::cyrus::CyrusSecurityLayer::canEncode()

Backtrace looks like this:
  Core was generated by `/mnt/tests/distribution/MRG/Messaging/qpid_common/clients/c++/qpid-send --broke'.
  Program terminated with signal 11, Segmentation fault.

As result of above crash-dump, c++ client is unable to GSSAPI authenticate when protocol AMQP1.0 is selected, AMQP0-10 works as expected:

How reproducible:
100%

Steps to Reproduce:
1. prepare kerberosv5 infrastructure
2. start broker
3. qpid-send --broker <host>:53542 -a amq.direct --connection-options "{sasl_mechanisms: GSSAPI, protocol: amqp1.0, username: <user>}" --content-string "Hi"

Actual results:
client unable to authenticate and crashing

Expected results:
client able to authenticate without crashing
