Log:
- Implement Phase 0 Ex initialization (Resource, Lookaside initialization) and generic Ex
initialization routine.
- Clear the crypto exponent on boot-up.
- Set default global flags for checked builds.
- Set NtSystemRoot (SharedUserData) to C:<NT BOOT PATH> on startup.
- Cleanup lookas.c file and implement routines to initialize the system lookaside list in
phase 0.
