Class DLGInputStream defined in DLexerBase.h has a virtual method but no
virtual destructor.
This commit add an empty virtual destructor to avoid potential
memory/resource leak when an object of a class derived from class
DLGInputStream is deleted through a pointer to the DLGInputStream class.

For classes that contain dynamically allocated data members, copy
constructor and assignment operator should be implemented or both
operations should be prohibited to avoid freeing freed memory caused by
shallow copy.
This commit declares both copy constructor and assignment operator as
'private' for classes that contain dynamically allocated data members.
This will prevent freeing already freed memory.
