[NTOSKRNL]: Implement last bits of session space support (minus session pool). Processes now have a ->Session pointer! Implement and enable MmSessionId in a bunch of places.
[NTOSKRNL]: Set MiSessionSpaceWs address and use where needed.
[NTOSKRNL]: Initialize the session working set, and add support to MiLockWorkingSet and MiUnlockWorkingSet for session WS.
[NTOSKRNL]: Implement MiSessionAddProcess and MiSessionRemoveProcess which does the work required for this.
[NTOSKRNL]: Fix IoGetIrpRequestorProcess.
In my private branch, MmMapViewInSessionSpace is working fine for the user and GDI heaps. Will enable after TestBot tests.
