QPID-676: Jonathan Robie's C++ examples.

Made the following alterations for recent C++ API changes:
 - use arg:: namespace for Session keyword arguments.
 - removed trailing _ on session method names.

cpp/examples/Makefile.am calls make in each example directory with
flags to build examples from headers/libraries SVN checkout.

Examples themselves have a plain Makefile (not automake) which will
work as is if qpid is installed in standard places.
