- Towards WinDivert 1.1:
* Re-brand "DIVERT" to "WINDIVERT" throughout the code-base.
* New flags:
  > WINDIVERT_FLAG_PASSTHRU: Do not drop nor capture packets.  Useful
    for injection-only handles.
  > WINDIVERT_FLAG_NO_CHECKSUM: Do not guarantee that diverted packets
    have a correct checksum.
  NOTE: Not yet tested!
* New default values and limits for various WinDivert parameters,
  including WINDIVERT_PARAM_QUEUE_LEN, WINDIVERT_PARAM_QUEUE_TIME, and
  the maximum filter length.
* New extended WinDivert functions that support asynchronous I/O:
  > WinDivertRecvEx(..)
  > WinDivertSendEx(..)
  NOTE: Not yet tested!
* The WinDivert driver now services reads (receives) out-of-band.
  The motivation is because WFP callouts are run at DISPATCH_LEVEL, so
  we should not be doing expensive work in the ClassifyFn.  This is also
  the same reason why the filter length has been restricted.
