Merged eb/binstats -r3848:3906 into trunk. These changes
(1) fix a problem with gr_feval* where when called from a live flowgraph, they resulted in the call back into Python occuring without holding the Global Interpreter Lock causing a SIGSEGV. (2) add gr_bin_statistics_f which combines statistics gathering with a control state machine that allows spectrum sensing or related applications that need to step through the spectrum to be built. (3) usrp_spectrum_sense.py which ties all this together in an application which steps through the spectrum a chunk at a time and gathers statistics. In the current version, the stats are gathered by nothing is done with them. Think of this as the framework for a real application. This code may require tuning of the --tune-delay and --dwell-delay timeouts to ensure that the samples being processed are associated with the given center frequency. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@3907 221aa14e-8319-0410-a670-987f0aec2ac5
