cf34beebb0 Remove extra call to switchctrl_set and global switchctrl variable. 
This call is not required since the GPIOs are already configured in
rf_path_pin_setup(). The global switchctrl is not used anywhere else.

eec6963759 Initialise RF path GPIOs to safe settings. 
Previously these calls were leaving the amplifiers on, since the
control settings passed were missing SWITCHCTRL_NO_TX_AMP_PWR and
SWITCHCTRL_NO_RX_AMP_PWR. Use the predefined SWITCHCTRL_SAFE here.

Also move these calls before setting the GPIO pins to output mode,
to avoid driving them to the wrong states briefly first.

e53b9d5717 Fix hang in TX when a libusb error occurs. 
Where our callback is called with a status other than COMPLETED,
something abnormal has happened and we no longer want to either
submit further transfers or await a flush. So clear the streaming
and flush flags, and proceed to transfer_finished.

Do the same in the case where libusb_submit_transfer fails when
called to submit the flush transfer.

f4202d1163 hackrf_transfer: Don't skip preload stats in RX 
Fixes a bug introduced in 8a9af7a: Statistics skipped for initial
buffers not only when preloaded in TX mode but also in RX mode with no
preloading.

The total bytes transferred may appear inflated in RX mode when
receiving a small number of samples with -n, but the stats represent
data transferred over USB, some of which may have been discarded by the
host.

f1e34b7cea Correct the calculation of dBfs signal level. 
dBFS is defined in AES Standard AES17-1998, IEC 61606, and ITU-T Recs.
P.381 and P.382, such that the RMS value of a full-scale sine wave is
designated 0 dBFS.

A full scale sine wave on HackRF has the range -127 to 127.

We calculate the full scale ratio relative to a signal in which both I
and Q are held at 127. This represents a signal with sqrt(2) times
the amplitude, and thus twice the power, of a full scale sine wave.

Therefore to obtain dBfs by the above definition, we add 3dB.
