Support for the original FUNcube Dongle used to live in GNU Radio's
gr-fcd module, which was removed in version 3.8. As a result, gr-osmosdr
lost support for both FUNcube Dongle and FUNcube Dongle Pro+.
The gr-fcdproplus out-of-tree module subsequently added support for the
original FUNcube Dongle, meaning that it now supports both types. As a
result, FUNcube support can easily be restored in gr-osmosdr. The
now.

XXX
The gnuradio block https://github.com/dl1ksv/gr-fcdproplus must be
installed before building gr-osmosdr.
Available named gains:
Dongle Classic:
LNA: -5 to 30 dB, in 2.5 dB steps
MIX: 4 or 12 dB
Dongle Pro+:
LNA: 0 or 1, meaning off/on only. no information about real values.
MIX: 0 or 1, meaning off/on only. no information about real values.
BB: 0 to 59 dB, in 1 dB steps
This patch also introduces optional "device" and "type" arguments which
allow to override the values automatically picked by gr-osmosdr:
osmocom_fft -a "fcd,device=hw:2,type=2"
The "device" argument overrides the audio device used by the underlying
driver to access the dongle's IQ sample stream.
The "type" argument selects the dongle type, 1 for Classic, 2 for Pro+.
Thanks to Alexey Bazhin for the initial patch and Volker Schroer for
testing.
