Log:
[CSRSS]: Remove unneeded initialization code, and move Win32k.sys related initailization
to win32csr. Note that the "VDM IVT" stuff should move to videoprt's handler
for IRP_MJ_CREATE, and opening the "\\DISPLAY1" needs to go in Win32k.sys (under
NtUserInitialize I think).
[BOOT REGISTRY]: Cleanup subsystem entries to match Windows.
