grc: rework the probe blocks and how they fit into grc
Removed the source on all probe blocks.
Advertise the probe-able function in the docs.
Added missing signal probe block.
Removed probe function and variable sink blocks.
Removed all supporting grc_gnuradio python files.
Added variable_function_probe block that can probe arbitrary functions on a block.
All the code needed by the function probe is available is the make tag.
To display the value of a probe block, use the variable probe block, and a gui widget.
To disply the value of a stream, do the same but use the signal probe block.
Simple see :-)
If more types other than floats need to be read from the stream,
the signal probe should be extended.
