Dimitri Stolnikov 0edfcfcba0 rtl: remove residue DC component introduced by RTL chip 
received from Juha Vierinen:

A student here noticed that there is dc bias even with the rafael tuner.
We looked into this issue and found that using 127.4f instead of 127.5f
removes this bias. I assume this is associated with a bug in the digital
downconversion of the RTL chip. This change fixes the problem.

Dimitri Stolnikov 3ce7c33981 fcd: add support for FUNcube Dongle Pro+ 
The gnuradio block https://github.com/dl1ksv/gr-fcdproplus must be
installed before building gr-osmosdr.

Available named gains:

Dongle Classic:

LNA: -5 to 30 dB, in 2.5 dB steps
MIX: 4 or 12 dB

Dongle Pro+:

LNA: 0 or 1, meaning off/on only. no information about real values.
MIX: 0 or 1, meaning off/on only. no information about real values.
BB: 0 to 59 dB, in 1 dB steps

This patch also introduces optional "device" and "type" arguments which
allow to override the values automatically picked by gr-osmosdr:

osmocom_fft -a "fcd,device=hw:2,type=2"

The "device" argument overrides the audio device used by the underlying
driver to access the dongle's IQ sample stream.

The "type" argument selects the dongle type, 1 for Classic, 2 for Pro+.

Thanks to Alexey Bazhin for the initial patch and Volker Schroer for
testing.

Dimitri Stolnikov 7a129238b7 hackrf: set the default sample rate to 10M 
this prevents a regression with early firmware who did not have 8M rate
but 5M instead. they both had 10M, so we use this as default.
