basil00 4f7ff88664 Add batched recv/send to WinDivert (#156). 
This change allows multiple packets to be
received/sent at once, reducing overheads.  To
exploit this feature, applications need to use
the WinDivertRecvEx()/WinDivertSendEx()
functions with the new addrLen parameter.  The
passthru example has been modified to use
batching.

The DEBUG flag has been retired since it
conflicts with batching, and was not very
useful anyway.

basil00 6250568974 Add a new FLOW layer into WinDivert. 
Adds a new WINDIVERT_LAYER_FLOW layer that can:
- Track when flows are established
- Track when existing flows are deleted

basil00 822dca9c3f Use snprintf() instead of sprintf_s(). 
The latter does not seem to work for MINGW.

basil00 1543e958e6 Dual-license WinDivert under the LGPLv3 and GPLv2. 
This allows projects that are strictly "GPLv2
only" to use WinDivert without licensing issues.
See the FSF's compatibility matrix here:
https://www.gnu.org/licenses/gpl-faq.en.html

This change does not affect existing projects
that can continue to use the LGPLv3 as before.

Also, bump the WinDivert version to 1.4.1.

basil00 aea3a3a858 Add support for pseudo IP/TCP/UDP checksums. 
Most NIC cards support checksum offloading,
meaning that it is not necessary to calculate the
full IP/TCP/UDP checksums for injected packets.
WINDIVERT_ADDRESS has been extended to include 3
extra flags that indicate if the packet has full
or pseudo checksums.  This is a WIP.

Streamdump demonstrates how to handle streams using WinDivert.

This is a WIP.
