4031d6ed04 tuner_fc0012: use new cleaned-up driver 
The driver was taken from http://git.linuxtv.org/ and adapted
for librtlsdr. Manual gain will be added in a follow-up commit.

75548c8bf3 tuner_fc0013: improve tuning resolution 
We now use Hz instead of kHz for the internal
calculations, and thus improve the tuning resolution
to ~50 Hz (tested with DAB).

505f40d9a0 introduce api function to read usb string descriptors 
This API allows to read manufacturer and product names as well as the
serial number advertized by the device on the bus.

fdc7bc978b add an initial version of rtl_test 
This tool allows to check for lost samples (and thus check the USB
connection), as well as benchmark the Elonics E4000 tunable range.

bad6fb080b introduce api to configure crystal oscillator frequency 
Usually both, the RTL and the tuner ICs use the same clock. Changing the
clock may make sense if you are applying an external clock to the tuner
or to compensate the frequency (and samplerate) error caused by the
original cheap crystal.

This commit covers all tuner drivers except of the Fitipower FC2580
