basil00 e306d0058b WinDivert filter language improvements.
- Add "length" for total packet length.
- Add "timestamp" for timestamp filtering.
- All filter language numbers are now signed.
- Add new macros: TRUE, FALSE, TCP, UDP, ICMP &
  ICMPV6.
- Future-proof the WINDIVERT_FILTER struct.

basil00 d29688ea83 Redesign the WinDivert SOCKET layer.
- Socket (& flow) events are now associated with
  a endpointId/parentEndpointId pair that allows
  the tracking of socket operations.
- A single socket CLOSE event replaces the UNBIND
  and DISCONNECT events.
- A new flag addr.Sniffed indicates if the event
  was sniffed or not.  Some events (CLOSE) are
  always sniffed, regardless of the flags.
- All filter language numbers are now 128bit.
- socketdump.exe can now optionally block events.

basil00 8fcb4313b6 WinDivert 2.0 API, service & documentation fixes.
- Make WinDivertRecv() and WinDivertSend() arg
  ordering match the Ex versions.
- Put the WinDivertHelperParsePacket() protocol
  arg after the IP headers.
- WinDivert service handling is now protected by
  a mutex.
- Debug the "uninstall" command for windivertctl.
  It can now uninstall the WinDivert driver &
  not leave the WinDivert service in a "pending"
  state.
- Document WinDivert performance tips.

basil00 7fa04945c0 Various WinDivert improvements.
- Add UNBIND/DISCONNECT events to the SOCKET
  layer.  These events can only be sniffed.
- Remove the RECV_PARTIAL flag.  The user
  application can just ignore the error code
  instead.
- WINDIVERT_ADDRESS is now 64bytes.  Some extra
  padding added for future-proofing.
- Ignore SOCKET-layer REAUTHORIZE.
- The REFLECT layer returns the filter object
  directly (no IPv4 "pseudo" packet).

basil00 fd75e6d42a Add a new SOCKET layer to WinDivert (see #156).
Adds a new SOCKET layer for monitoring socket
events, such as BIND, LISTEN, CONNECT,
and ACCEPT.  These events occur before the
flow is established (and unlike the FLOW layer)
it is possible to block/drop SOCKET events.

Otherwise, this layer is very similar to the
FLOW layer, so the PID is available and injection
is not possible.  This commit should be
considered to be a WIP.

Other changes:
- New socketdump.exe sample.  Prints socket
  events.
- Improve IPv6 address parsing.
- New helper functions:
  * WinDivertHelperFormatIPv4Address
  * WinDivertHelperFormatIPv6Address
- Fix REFLECT bugs.
- The network 5-tuple can now be accessed at
  the NETWORK layer.
- Various cleanups.
