Dimitri Stolnikov 5943919828 hackrf: introduce bias=0|1 and bias_tx=0|1 parameters
... to support antenna/phantom power via a new device argument "bias"
(to match Airspy's existing bias power syntax). 0=disable and 1=enable.
I also added a device argument to control bias power at transmit time. I
named this option differently - "bias_tx" - to avoid accidentally
enabling bias power in transmit mode when an LNA may be attached in an
input amplifier configuration.

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 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
