tuner_fc001x: check if PLL values are within boundaries
...
This fixes the issue of the FC0013 locking up at frequencies
between 928.0 and 950.0 MHz, which happened because
the numerator of the fraction exceeded its 5 bit limit.
For the tuner to behave normally again, the dongle needed
to be replugged.
For the FC0013 this now results in a small gap between
948.6 MHz and 950.0 MHz, where no valid PLL values
are existant.
For the FC0012 tuning is aborted when the maximum
frequency has been reached (948.6 MHz).

add support for direct sampling mode
...
This commit adds the function rtlsdr_set_direct_sampling()
which can be used to enable/disable a mode where the
RTL2832 acts as a direct sampling receiver.
This mode disables the tuner, and by attaching a long
wire, or better, a 50Ω to 200Ω transformer and a lowpass-
filter to the In-phase ADC input (pin 1 or 2 of the RTL2832,
whereas pin 1 is at the molded dot) it is possible to listen to
shortwave radio stations. The coupling capacitors can be
left in place, but for better results they should be removed.
Tuning in this mode is done with the DDC, and since the
ADC samples with 28.8 MHz, tuning is possible from 0 to
28.8 MHz.
