[IMP]

- IsUndefined returns const bool& now.
- Replace kUndefined with kNull now.
- Remove ML_ from macros in newstd.hxx.
- Rename NSyscall to NSyscallInterface, which is a ref counted class now.
- Rename MBCIType to PowerID
- Update ToDos.
- Update NewFS root catalog name.
- Fix JSON 'null' initialization.
- Add Json to variant object.
- Replace kPointer with kBlob in variant kinds.
- Add Leak() method to variant.
