0961a76f26 Fix libusb usage for at least freebsd around the worker thread and transfer cancellation 
On at least freebsd-13 trying to cancel a transfer whilst the libusb thread
is not running results in the transfers not completing cancellation.
The next time they're attempted to be re-added the libusb code thinks
they're still active, and returns BUSY on the buffers.

This causes gqrx to error out when one makes DSP changes or stops/starts it.
You have to restart gqrx to fix it.

After digging into it a bit, the libusb code expects that you're actively
running the main loop in order to have some deferred actions run in the
context of said main loop thread.  This includes processing cancelled
transfers - the callbacks have to be run (if they exist) before the
buffers are properly cancelled and have their tracking metadata (a couple of
private pointers and state) removed from inside of libusb.

This patch does the following:

* separate out adding and cancelling transfers from the libusb worker thread
  create/destroy path
* create the libusb worker thread when opening the device
* destroy the libusb worker thread when closing the device
* only add and cancel transfers when starting and stopping tx/rx
* handle cancelled transfers gracefully in the USB callback

Whilst here, also make the libusb device memory zeroed by using
calloc instead of malloc.

This fixes all of the weird libusb related buffer management problems
on FreeBSD.

d8250c6396 Don't re-init bulk endpoints on every set_transceiver_mode call 
Previously the firmware would re-initialise the bulk endpoints on
every transceiver mode change including a USB data toggle reset,
which could cause the first bulk packet (512-bytes) to be dropped
by the host if the PID no longer matched.

ecd82e81c1 remove specific sample rate recommendations 
HackRF One supports arbitrary sample rates from 2 Msps to 20 Msps.  In
early development we had ideas about preferred sample rates that we no
longer consider valid.
