Log:
[AFD]
- We really do need to count the outstanding send IRP in our pending send count (with a
detailed explanation of the reason included in the code)
- Wait on an outstanding send IRP to dispatch the disconnect
- When we receive a FIN from the other side and our receive comes back with 0 data, only
close receiving on the socket because sending is still legal in this state
- Fixes many bugs on the ws2_32_winetest sock and likely lots of other partial disconnect
related stuff
- Retest network related hanging bugs after this please (ftp dir hang is fixed)
