Steve Markgraf e1bf239a6d lib: add KWorld KW-UB450-T to device list 
The TUA9001 tuner it uses is unsupported
at the moment, though.

Steve Markgraf 3e17ef2b55 lib: don't detach kernel driver by default 
Since this feature also disconnects running instances
of librtlsdr that claimed the device, it is now disabled
by default and can only be enabled at compile time.

To enable it when building with cmake:
cmake . -DDETACH_KERNEL_DRIVER=ON

To enable it when building with automake:
./configure --enable-driver-detach

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 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.
