Log:
Work in progress.  Converted hier_block2 class to not use 'define_component'
anymore.  This considerable simplifies both the internal code as well as
the user interface, which is now very much like the existing gr.flow_graph 
API.

The code is failing QA at the moment (tracking down a segfault, and one
failure case in 'disconnect').  Also, none of the Python code that uses
hier_block2 has been converted.
