Will Glynn 4914b5d431 rtl_adsb: Fix invalid memory access 
single_manchester() considers both i and i+1, but the loop only
tests that i is in bounds. This causes undefined behavior, including
but not limited to a SIGBUS-related crash on Mac OS X.

(And also, we should not enter an infinite loop, caused by applying
an patch I sent that didn't also change the while condition.)

Steve Markgraf f1803fe10f lib: special handling of dongle disconnect for OS != win32 
libusb reacts differently to a device loss during runtime,
and sporadic errors can happen when starting a second
instance interfacing another dongle, thus we need to wait
for all transfers to fail before assuming the dongle has
been removed.

Steve Markgraf a943a2ed25 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).

Steve Markgraf fc5881d4cd 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.

Steve Markgraf 5f88049c0c rtlsdr_i2c_rad_reg: fix uninitialized variable

Thanks to Christoph Gommel for reporting this issue.
