Minor API improvements.

- addr.Pseudo*Checksum flags replaced by simpler
  addr.*Checksum flags.
- WinDivertHelperParsePacket() can now handle
  batched packets.
- WinDivertHelperParsePacket() can now return the
  transport protocol.
- WinDivertHelperCalcChecksums() can now handle
  batched packets.
- WinDivertHelperCalcChecksums() now sets address
  checksum flags that were calculated.
- A bunch of WINDIVERT_* macros have been moved
  to windivert.h for windivert_device.h.
