gnuradio-examples, gr-audio: moved audio Python and C++ examples into gr-audio

This begins a transition of examples from a separate gnuradio-examples component
into an examples directory with the component they go with.  In this commit:

gnuradio-examples/c++/audio/   => gr-audio/examples/c++
gnuradio-examples/python/audio => gr-audio/examples/python

The system installation directory remains $PREFIX/share/gnuradio/examples/audio

- * be used in any way a regular pointer can.  Shared pointers created this way
