Support remote operations in wineserver

They provide another kind of interprocess communications.
We should force another process to execute desired operation.
Added requests help to supply parameters and obtain the result.
If we would use service thread (that was removed from wine
long ago, do not mix with service thread i'm going to introduce in
service subsystem), win32 api would be enough.

No.
Services is another story. I'm not going to use RPC as windows does.
Now it's essential to get local services working and RPC will only
obstruct the code.
