Dimitri Stolnikov 0ee591f163 netsdr: add support for RFSPACE NetSDR receiver 
- implements broadcast UDP based device discovery
- prints device information (serial/versions) on startup
- reads available frequency range(s) from the device
- integrity checks of IQ stream using sequence numbers
- automatic bandpass or a wideband lowpass selectable

The following named gain stages are available:

ATT: -30 to 0 dB, in 10dB steps

Known limitations:

- setting the sample rate is possible only before the
  flowgraph has been started

Dimitri Stolnikov dd7d584137 hackrf: implement device discovery 
Unfortunately libhackrf still doesn't offer a way to enumerate devices
*or* to open a specific device by index or it's serial number. Thus we
have implemented a rather hack-ish way to detect the presence of a
device by trying to open it and closing right after that.

Jon Szymaniak cbf791469c bladeRF: Refactored buffering scheme in sink 
Removed the use of an intermediate sample FIFO in the sink
implementation. Note the the FIFO has not been moved out of
bladerf_common --> bladerf_source_c in this commit.

work() now handles converting samples from complex to SC16_Q12, and filling
"transmit-ready" buffers. The callbacks are now only responsible for
marking the provided buffer free, and returning the next buffer.

It appears that a small deadlock issues remains in this changest, which
can be induced by:
 1: Using a small sample rate (160Khz)
 2: Switching back and forth between sinusoid <-> GSM burst

 In this case, it appears that work() is blocked waiting for a buffer to
 become free. More investigation here is required...

Dimitri Stolnikov e5f7b28093 bladerf: add support for nuand LLC bladeRF (WIP) 
This is based on the original work (https://github.com/Nuand/gr-osmosdr)
done by folks at nuand LLC for the gr3.6 branch of gr-osmosdr.

The following modifications have been done in this commit:

* port to gr-osmosdr master codebase (gr3.7)
* moved shared properties to bladerf_common
* added & verified IF filter bandwidth setters
* set LMS6002D registers with values taken from FAQ 5.27
* print device information (serial/versions) on startup
* added fpga= and fw= device arguments to program MCU/FPGA
* added bladerf=# dev. arg. to select a specific bladeRF
* grc gain field controls RF path VGA for RX/TX
* grc BB gain field controls BB path VGA for RX/TX

Usage example:

osmocom_fft -a "bladerf,fpga=/tmp/hostedx115.rbf"

The following RX named gain stages are available:

LNA: 0 to 6 dB, in 3dB steps
VGA1: 5 to 30 dB, in 1dB steps; nonlinear mapping done inside the lib
VGA2: 0 to 60 dB, in 3dB steps; not recommended to be used above 30dB

The following TX named gain stages are available:

VGA1: -35 to -4 dB, in 1dB steps, BB side
VGA2: 0 to 25 dB, in 1dB steps, RF side

Thanks a lot to the team of nuand LLC for this major contribution.

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.
