rtl_tcp: Throw an exception if TCP connection fails
...
Currently, rtl_tcp_source_c repeatedly calls ::connect until it
succeeds. This can result in 100% CPU utilization and/or a lot of
network traffic. In addition, GUI applications like Gqrx freeze up.
To solve these problems, I've changed the code to report an error
if ::connect fails.

RTL-TCP: Convert to single class model
...
The existing RTL TCP driver is quite different from its brother RTL_SDR.
It's much more complicated, uses gr::blocks::deinterleave and
gr::blocks::float_to_complex, and generally doesn't work correctly
(e.g. https://github.com/csete/gqrx/issues/99
Spectrum is mirrored when filter or demodulator changes (rtl_tcp) #99 )
I've converted the RTL TCP driver to the model used by RTL_SDR,
simplifying it in the process, and fixing the GQRX issue.
