services: Fill in the functions between implemented functions in svcctl.idl so that it our remoting code is wire-compatible with NT.

Add the necessary stubs for these in services.exe.

Make the functions that deal with the service database more object-oriented.

Add a finer-grained locking architecture.

services: Remove dependency on service name being determined correctly in order for the two ends on the control pipe to meet up.

Instead use the mechanism used by native which uses 
\\.\pipe\net\NtControlPipeN.

Also remove the service startup event set by StartServiceCtrlDispatcher 
as we wait for the service status to change instead.

This also changes the architecture such that services.exe is the server 
end of the control pipe and the service is the client end.

services: Move CreateService, OpenService and DeleteService implementations from advapi32.dll to services.exe.

wined3d: Add a depthstencil flag to the formats table and make use of it in CheckDepthStencilCapability.
