* Unit test updates * Lambda syntax cleanup * Use new-style casts * Use std::none_of when saving the cache * Use to_integer instead of casts * Use accessors for getting CDB data * Made ctrl_t private * Improved encapsulation * Replaced pointers by references * Removed all remaining occurrences of DWORD and BYTE, making os.h obsolete
