CodeWeavers did this work for supporting the optional HTTP connection
method of Outlook 2003/2007 (must be running with Windows versions set
to XP or higher to see this option).
This was written before Microsoft publicly released a specification
for the RPC over HTTP protocol and so was developed by examining
traffic flowing between a Windows client and an IIS server.
The actual sending of the request is still done in I_RpcSendReceive though.
Disallow the server from calling I_RpcSend and I_RpcReceive to allow
simplification of the code. The releasing of the connection is now done
in I_RpcFreeBuffer.
Implement I_RpcNegotiateTransferSyntax.
