Dimitri Stolnikov b9489aecdf uhd: implement stream arguments for sample format 
cpu_format: sc8, sc16, fc32, fc64
otw_format: sc8, sc16
fullscale: specifies the full-scale amplitude when using floats.
peak: specifies a fractional sample level to calculate scaling with the
sc8 wire format.

example:

osmocom_fft -a uhd,otw_format=sc8,fpga=usrp1_fpga_4rx.rbf -s 16M

Dimitri Stolnikov 8ee05d3196 uhd: catch exceptions from dc offset & iq imbalance setters 
since dc offset / iq imbalance is not implemented for recent USRPs this
might cause undesired behavior in GRC. As a workaround we do not pass
them to the caller but print them to the stderr.

Dimitri Stolnikov ac95af24fa uhd: pass through only the requested number of channels 
B210 USRP appears as a 2-channel device by default. We prevent weird
application behavior by restricting the number of connected channels to
the value given via nchan= argument (1 by default).

Dimitri Stolnikov 7e55cb9224 introduce osmosdr namespace, remove _c suffix 
- the namespace conversion adopts the common gnuradio coding guidelines
- suffix removal is a preparation to support 8/16 bit complex data types

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 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());

Dimitri Stolnikov 52b5a8a4d3 uhd: added UHD as dependency for the gr-uhd based module 
this may be required for compilation since the gnuradio trunk doesn't
provide UHD's include path via pkg-config.
