Please don't include changes to automatically generated files 
(server_protocol.h, request.h, trace.c).

Please get everything outside of SERVER_START_REQ()/SERVER_END_REQ except 
actual wine_server function calls and handling of returned result(s). Some 
functions can do their own server calls and you will have a deadlock.

This is wrong, you can't clear token user - it always have to be set, or you 
risking an assert in get_token_sid. Which means you have to validate the 
data user passes in.
