Log:
Refactored kernel MCB management:
- Splitted existing functions in two files largemcb.c and mcb.c
- Stubbed (from win2k3) FsRtlInitializeBaseMcb, FsRtlUninitializeBaseMcb,
FsRtlResetBaseMcb, FsRtlTruncateBaseMcb, FsRtlAddBaseMcbEntry, FsRtlRemoveBaseMcbEntry,
FsRtlLookupBaseMcbEntry, FsRtlLookupLastBaseMcbEntry, FsRtlLookupLastBaseMcbEntryAndIndex,
FsRtlGetNextBaseMcbEntry, FsRtlSplitBaseMcb
- Implemented FsRtlNumberOfRunsInBaseMcb
- Added missing definitions to ntifs.h
