0 is csrsrv.dll, and it's used by the other servers (ie, base and 
console connect to server 0 (but they use server-to-server calls which 
are much faster, see my ntdll/csr changes that you have)). 3 is 
winsrv.dll and it's what user32.dll connects to. winsrv handles all 
sorts of misc stuff (like exitwindowsex) and also has some connections 
with win32k.sys. After commiting csr I'll probably work on 3 inside 
winsrv, since it's easier to implement then basesrv.dll (which is huge, 
since it handles all SxS stuff too now).

winsrv.dll.

Oh, and I made a slight mistake, i said that the Console Server was 
inside basesrv.dll, it's not. It's inside winsrv.dll, my apologies.
Here are the functions, for information:

@8 of course since they are all CSR APIs (IN PCSR_API_MESSAGE, OUT ULONG 
Result)

And, as KJK stated, the APIs for Server 3 are:

SrvExitWindowsEx
SrvEndTask
SrvLogon
SrvRegisterServicesProcess
SrvActivateDebugger
SrvGetThreadConsoleDesktop
SrvDeviceEvent
SrvRegisterLogonProcess
SrvCreateSystemThreads
SrvRecordShutdownReason

(Note that winsrv handles WM_DEVICE event or changed APIs, with 
SrvDeviceEvent)

Oh, and before I forget, basesrv is also largely responsible for VDM.
