Log:
- Implement loading of NLS data, SYSTEM hive data (just simple loading into memory,
without any kind of parsing or even checking if that data is correct)
- Add a function for creating a stub of hardware config (config consisting of only one
node - root)
- Implement two steps of LPB initialization (names Phase 0 and Phase 1 are used internally
by me, and doesn't correspond to anything)
- Implement a WinLdrSetupForNt, which allocates and initializes some specific structures
(PCR, TSS, GDT, IDT)
- Respectively enable calls to these functions from LoadAndBootWindows()
