RTL-SDR: convert _lut to float[] to reduce size by a factor of 256
...
The _lut is being indexed by I + Q (16 bits = 65536 entries), however
both samples can be processed independently, resulting in 8-bit LUT.
Saves a bit of RAM and CPU cache.

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

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