Dimitri Stolnikov 911f916b3b hackrf: don't set automatic bandwidth on samplerate change 
automatic bandwidth selection may be triggered by calling
set_bandwidth(0) after changing the sample rate

Jon Szymaniak a0b534d118 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 65e34f6863 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 7058fd6610 fcd: add support for FUNcube Dongle Pro+ 
The "3.6" branch of the gnuradio block https://github.com/dl1ksv/gr-

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 2d02ae9b83 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 ba5c6c8da6 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.

Dimitri Stolnikov a5bdb27240 hackrf: add TX support (wip) 
features:

- gain control for AMP & VGA
- frequency error correction
- automatic baseband filter
- up to 20M sampling rate

limitations:

- no DC offset correction implemented (yet)
- high sampling rates may not work on slow machines

the following TX named gain stages are available:

RF: MGA-81563, switchable 0 or 14dB
IF: MAX2837 VGA, 0 to 47dB in 1dB steps

Dimitri Stolnikov 37f6383c7c hackf: implement start & stop methods 
This allows a block to enable an associated driver to begin
transfering data just before we start to execute the scheduler.
The end result is that this reduces latency in the pipeline
when dealing with audio devices, usrps, etc.
