(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.

sky at the time or not.
Increased the difficulty of the "gauntlet" that "hits" in the SETI mode
have to run through in order to be considered a hit. Hard to test :-)
Added intensity levels to SETI hit logging. This will allow post-facto
gaussian profile determination for any hits that are found.

continuous frequency-scanning, the continuum data will be invalid
anyway, and of little use.
This saves a little bit of CPU, so I've been able to get a 25Khz
FFT with a length of 32768 bins, for continued sub-1Hz resolution,
but with a wider instantaneous bandwidth. For some reason, though,
there's a "knee" in the curve, and running at 50Khz sampling increases
the CPU consumption by a much larger factor than you'd expect.

prereq in GNU make, implied source for pattern rule in BSD make)

add hints for pkgsrc (dependencies, how to link against them, avoid suggesing to install -devel)
adjust language to be more OS-neutral
change PYTHONPATH hint example to be 2.4 since that's more likely to be right if blindly copied.

logging is more directly plugged into the signal-processing chain,
rather than being a side-effect of plotting. For spectral data, had it
copy spectral bins into a data buffer that gets dumped once per second
in the UI, same as continuum data.
Added --calib_coeff and --calib_offset command-line parameters to scale
the output of the continuum detector.
