[NTOS]: Minimal stubbed support for some large page functionality in case it gets implemented later and these things would've been ignored. One critical change is that now the MmProcessList is initialized, and the system process is added to it. Other processes should be added later.
[NTOS]: Add stubbed support for parsing the registry list of drivers that should have large pages enabled.
[NTOS]: Initialize the loaded module list before working set work.
[NTOS]: Reload the boot drivers much earlier, as part of ARM3 initialization.
[NTOS]: Start doing some minor MmResidentAvailablePages accounting during bootup.
[NTOS]: Start doing the math required for computing the appropriate MmSystemCacheWsMinimum on the booting system (based on RAM).
[NTOS]: Now that we use the HAL heap, add the code to scan it for I/O mappings. These are dangerous because we need to sync up caching attributes (not yet used in ReactOS, so not a problem for now).
[NTOS]: Add more header definitions, and helper definitions such as PDE_MAPPED_VA instead of doing the math by hand.
[NTOS]: Move MmPageEntireDriver and MmResetDriverPaging to sysldr.c since drvmgmt.c is more for Driver Verifier-style functionality.
