Removed the linked list structure, locking, and malloc/free on each USB callback. Replaced it with a non blocking ring buffer for performance. This resulted in a large performance improvement when using an Raspberry Pi or Raspberry Pi Zero W as a rtl_tcp server. The sample rate could be doubled and instead of wired ethernet wifi could be used. Frequnecy change lag was reduced greatly also. Signed-off-by: Stephen Blinick <stephen@stesoft.com>
