Dimitri Stolnikov eb76e35689 osmosdr/rtl/miri/hackrf: use 15 buffers by default 
folowing rtl-sdr commit 89f73b183f2dac9c0dd75beca4cf2f77f20c4a36

So far we had 32 * 256KB which was a bit overkill, 15 are more than
enough.

15 was chosen instead of 16 because at least on Linux there seems to be
a system-wide limit of 63 transfers (when they are 256KB large), so 4
dongles can be used on a single machine without lowering the default
transfer number.

Dimitri Stolnikov a71fbeeaa5 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.

Dimitri Stolnikov b3bbe0935e hackrf: don't set automatic bandwidth on samplerate change

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.

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.

To use the default (automatic) bandwidth filter selection, this should
be set to 0.

Dimitri Stolnikov 448206b2d2 hackrf: implement full control for RF/IF/BB gain stages
