1. fixed NtCreateProcess to do some buffer checks and moved the
implementation to an internal function so it can be shared with
PsCreateSystemProcess(). Also don't leak so many resources on failures
2. processes should acuire a cid handle for their unique process id
3. fixed several instances in structures where process ids were
DWORD/ULONG instead of HANDLEs
