Found with modernize-use-nullptr
NULL in C++ is 0 whereas it is a void pointer in C. Avoids implicit
conversions.

Most of the times each class has an associated constant so
allows to be able to define the constant at declaration time.

This allows to:
- reuse reference counting;
- avoid having to manually call g_free to release item memory;
- assure item is initialized;
- avoids some manual casts.
It will also allows to use smart pointers.

The patch seems pretty huge but mainly are mechanical steps:
- remove GObject declarations
- do not inherit from GObject
- add SPICE_CXX_GLIB_ALLOCATOR to avoid using C++ allocators
- CLASS_init and CLASS_constructor code goes into C++ constructor
- CLASS_dispose and CLASS_finalize code goes into C++ destructor
- g_object_new is replaced by new operator
- class members goes into virtual methods
- class parameters became argument to constructor
- use push-visibility.h and pop-visibility.h to limit visibility
- temporary use XXX_CAST for old GObject casts, they will
be replaced
- g_object_get is replaced by accessors

Make all RedChannelClient hierarchy a C++ class.
This allows to use virtual methods.
Added a normal contructor instead or properties and g_object_new.
As we remove GObject conversion macros I added a macro XXX_CAST
to create a function to replace the old macro.
They will be removed when more type safety is introduced.
There's a new SPICE_CXX_GLIB_ALLOCATOR macro in red-common.h.
This macro, added to a class define the class allocator allowing
to use, in this case, GLib for allocation. This to avoid C++ library
dependency and to initialize all structure to 0 (not all fields
are manually initialized, will be improved with more encapsulation).
Currently the methods are mainly public, access will be modified
when more encapsulation (all functions in method) are done.
Some classes are now defined in the header, C++ uses access to
limit accessibility but for efficiency and type safety/inline and
other features require types to be defined in the headers.
Some fields were moved from XxxPrivate structure to class, C++
has accessibility.
Many destructors are defined as protected to forbid the use of
stack, this as these objects uses internal reference counting
to have normal pointers. Maybe in the future pointers like
std::shared_ptr could be used instead.
Reference counting is now implemented very easily using atomic
operations.
