Dimitri Stolnikov ccff99ea4f uhd: add lo_offset argument 
This might be used to tune away from the noisy center region caused by
direct conversion receiver principle. The offset shall be choosen within
receiver (daughterboard) bandwidth.

Thanks to Marcus Leech & G0HWW for the original idea.

Dimitri Stolnikov c51b04ee74 don't throw exceptions inside a gr_hier_block2 ctor

been informed.

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());
