RFC: Pass ReadFile and WriteFile requests on sockets to ws2_32.dll

[Erich Hoover]

Attached is a patch to take kernel32/ntdll ReadFile and WriteFile
requests on sockets and pass them to WSARecv and WSASend.  This patch
is part of a series I'm working on for the infamous C&C networking bug
(Bug #7929). The functionality added by this patch was requested by a
previous RFC response so that ReadFile and WriteFile requests will
have all the same filtering as WSARecv and WSASend.  Any and all
feedback is greatly appreciated.
