Dimitri Stolnikov dee9d3e696 update available samplerates for rtl devices 
250k didn't work for TETRA and GMR, 2M has.

Steve Markgraf 0f25daec61 rtl: add direct_samp as device parameter 
This can be used to enable the direct sampling mode
of an rtlsdr stick, e.g.:

For input 1 (In-phase ADC):
rtl=0,direct_samp=1

For input 2 (Quadrature ADC):
rtl=0,direct_samp=2

Dimitri Stolnikov 86ec5d3b73 add if gain setter API for rtl-sdr 
and OsmoSDR devices

Observations lead to an useful gain
range from 15 to 30dB, a value of
24dB is used by default.

Dimitri Stolnikov 3ea0b38810 introduce device discovery api 
This API allows to acquire a list of devices connected to the host and
creates an argument string ready to be passed to a source object for
cunstruction.

Each device_t entry contains a "label" entry, which holds the generic
device name which may be shown to the user for device selection.

For certain radio hardware extended entries ("name", "serial", "type")
may be available to make bijective device addressing possible.

The argument string for target types "rtl_tcp" and "file" might be
constructed using the osmosdr::device_t class facilities.

Example:

 #include <osmosdr_device.h>
 #include <osmosdr_source_c.h>

osmosdr::devices_t devs = osmosdr::device::find();

BOOST_FOREACH(osmosdr::device_t &dev, devs) // try to create each dev
  osmosdr_source_c_sptr src = osmosdr_make_source_c(dev.to_string());
