Clayton Smith 137c568c60 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.

Krzysztof Halasa 26f93e4687 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.

Steve Markgraf 8cbde92c94 rtl/rtl_tcp: add 2.56e6 as 'good' sample rate 
Several tests have shown that this is the
highest sample rate where no samples
are being dropped on rtl devices.
