Code cleanup, especially casts, lambdas, data types, encapsulation (#952)
* 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
