2be1612e60 lib: Use GPIO P0 to toggle an (optional) bias-t 
At least one distributor of rtl-sdr dongles (rtl-sdr.com) added
a bias-t to their dongles which could be toggled via GPIO P0 of the
RTL2832U chip.

d892279085 Allow setting bandwidth for R820T 
This improves SDR performence for nearby channel interference.
As a sideeffect also improves dynamic range becase ADC is not overloaded
by onwanted singlas.

c5dc459fc5 Correct return code of e4k_reg_write(). 
In contradiction with the documentation, e4k_reg_write() was
returning the value 2 upon success (the number of bytes written),
not zero as documented.
Patched to return zero upon success.

As a consequence, this corrects also the return value of
e4k_reg_set_mask() and e4k_dc_offset_calibrate().

89f73b183f lib: change default number of transfers to 15 
So far we had 32 * 256KB which was a bit overkill,
15 are more than enough.

15 was chosen instead of 16 because at least on Linux
there seems to be a system-wide limit of 63 transfers
(when they are 256KB large), so 4 dongles can be used
on a single machine without lowering the default transfer
number.

5b0137abaf lib: handle events after canceling transfers 
Otherwise the new transfer status does not propagate
into the xfer->status and we try to cancel all transfers
twice.

Also replace the ifdefs with a single macro for backwards
compatibility.

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.

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.
