Denys Berkovskyy 2c171630fa lib: add missing 'goto' in tuner detection code 
Add missing ‘goto’ to avoid checks for other tuners when
R828D tuner is found.

Steve Markgraf a2bc5b5117 lib/cmake: check for libusb_handle_events_timeout_completed() 
libusb < 1.0.9 doesn't have libusb_handle_events_timeout_completed(),
but libusb <= 1.0.8 doesn't have version.h, so we need to check
for the function.

The cmake-code was borrowed from UHD, which also checks
for libusb_error_name(), we add that as well since it might come
handy later on.

Steve Markgraf 3409c0315f lib: speed up exiting from async handler 
Now we're using libusb_handle_events_timeout_completed()
instead of the deprecated libusb_handle_events_timeout(),
and notify our async state machine when rtlsdr_cancel_async()
is called. This speeds up exiting from any program that uses the
device asynchronously.

Steve Markgraf 003bd51167 lib: check for validity of sample rates 
Thanks to Joris van Rantwijk for finding what seems to be
a hardware limitation/bug (bit 28 of the rsamp register being
forced to the value of bit 27).

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.
